Storm Crux Prime Bowling Ball

(35 reviews) Write a Review
The design almost every Storm PBA tour player was demanding to be brought back. With the Catalyst Core, you, too, will bear witness to unprecedented power, increased entry angle, and a greater margin for error with its dynamic asymmetrical design and vertical cavity technology. The benefits of SPEC Solid Reactive can be truly appreciated on heavier conditions, especially when they begin to transition. When this coverstock encounters midlane friction, it digs in harder, unlike anything Storm has produced to date. In the heart of the ball lies the innovative Catalyst Core. The genius the design is in the cavity which lets the driller remove less mass with most layouts. No more second guesses or shots in the dark. The ease of drilling is self-evident in this design.

    Here today to do a ball review on the storm crux prime.The storm crux prime is using s-pec solid cover stock with a 2000 grit finish.After drilling one I can see where this ball can fit in alot of bowlers bags.I was really liking the original crux the roll and shape this ball had when is was going down the lane,now with the prime you can tell this ball is alot sooner but down lane alot smoother shape,not to jumpy of the dry as the original crux.Plus I really like how colourful this ball is when going down the lane you can tell from anywhere in the bowling ally that's a crux prime lol.Great ball to start with and very good for more volume patterns,ive also took it down to 1000ab and you can tell this cover stock likes to chew threw the oil with ease.Bowlers with little more speed can benefit with a ball like this.

    Storm Crux Prime – 50 x 6 x 50 – 14lbs. Spec solid coverstock – 2000 grit – 6" plus flare The final ball added to my new 14lbs. arsenal is the Storm Crux Prime. Drilled for SPL and Brunswick lane panels I have been practicing on since my return to the sport a few weeks ago since my accident last year. I started with weaker stuff and working my way up to stronger stuff and found that this ball was WAY too much on the THS I bowled on normally. My home center is older HPL and a hard cliff at the end of the pattern, there is 2 other centers I like to bowl at and one has newer SPL and the other has really new Brunswick panels. With the RA value of the SPEC cover, it cuts through all the heavier oil and still has plenty of energy left to recover on the backends. To see conditioner sit on this ball for several seconds and it NOT soak into it was COMPLETELY amazing. Best heavy oil ball I have used in a while that has not diminished in performance over the past 30 games I have used it.

    The Storm Crux Prime is Storms newest Premier Line bowling release. The Crux Prime contains the Catalyst Core which is found in all of the Crux line of balls. The Prime is covered by Storms newest cover stock called the SPEC Solid Reactive cover. The ball is factory finished at 2000 grit. First off I want to talk about the new SPEC cover stock. The SPEC cover is designed to fit the new USBC rules for oil absorption. This cover is amazing. I've thrown a few practice sessions and 5 games at the USBC Open with it already and the cover still looks and feels dull like it did brand new. I can't wait for this cover to be available on future bowling balls. I drilled my prime pin down and stacked below my bridge. I drilled it specifically for Nationals. I wanted a good strong ball that can handle oil but with a layout that will roll earlier and stay smoother down lane. This is exactly what I got. This layout combined with the cover really helped me control the back end reaction on the tough USBC Open conditions. I found some success early with the Prime but when I started to have to migrate left, the ball because to strong in the front part of the lane where I had to ball down to get more backend reaction. On house shot conditions I've found the Prime to be very strong and the ball hits like a tank through the pins. Despite my layout choice I still find the Prime to have a good amount of backend reaction which makes it great for medium to long patterns and heavier volume of oil. For me the Prime is quite a bit stronger compared to the original Crux and Alpha Crux. I recommend this ball for anyone looking for a ball that can handle oil and who is not afraid to get left and loop the lane. This ball will cover may different types of oil patterns except maybe short patterns but its very versatile.

    My name is Doug Cutler and I am a Storm Staffer and I have had drilled 2 Crux primes and man both of these balls are awesome. My First Crux Prime I drilled 70 x 4 1/2 x 35 and the surface is 4000 grit. This ball I tried out of the box but man it was really strong and for the shot we were bowling on I had to bring the surface up to 4000 grit and man this is the ball I use right out of the bag. I am able to stay left early and keep my ball speed up and I am able to use this ball for about 2 1/2 games and then I go to my Pin down Crux prime and move right and open my angles up. This ball with this layout I can use it on THS, and Medium to Heavy Oil Patterns. My Second Crux Prime I drilled 45 x 4 1/2 x 70 and the surface is 3000 grit. This Crux I really like when there is carry down and man this balls does not read to early and it save more energy in the back and has a lot of shape and man it hits hard. I use this crux on Medium to Heavy Oil Patterns and you can use it on THS. I would say that this would not be a ball for short oil patterns. I have used these 2 crux primes a lot and if you liked the original crux you will love this crux also. This is a ball you will definitely need in you ball, so get to your local pro shop and purchase your Crux Prime if you have not gotten one yet. Storm hit another home run with this ball. #stormnation #cruxprime #bowlupastorm Doug Cutler Storm Staffer PBA Regional Champion

    PAP: 5 over 3/4 up Layout: Pin above bridge I was looking for a strong AYSM ball, that I could get left with, and not lose energy. With how I roll the ball, I typically can't get left of 20 with an ASYM without losing energy. Let me tell you, the Crux Prime is STRONG. I am able to play every part of the lane with this ball. I was extremely impressed with this piece. I can play 10-25 with this ball, and it will have plenty of energy going through the pins. It does read earlier, with it being a solid, but it still retains enough energy to get left with it. This is a must buy for your bag! #StormNation

    Layout 65x6x70 Went for smooth reaction, was not disappointed Bran New Spec cover with the tested Catalyst Core The Crux Prime is a very strong asymmetrical bowling ball. I like to use it on higher volume patterns for tournament play or on a fresh house shot. This ball reads the front part of the lane very quickly meaning you will more than likely want to open your angles when throwing this ball. Slightly more front to back than my physix. But overall smoother than the physix. This ball compliments The Phase 2 quite well as a 1,2 punch combination overall perfect piece to the bag if you are missing a solid asymmetrical ball.

    Layout: 25 x 5 x 40 My PAP: 4 7/8" x 3/4" up Axis Tilt: Between 3 and 8 degrees High Track Player Intent for this ball/layout: Wanted a strong midlane read that also blended out the backend from ver reacting but still with plenty of energy and angle into the pins. What I got: I was not disappointed. This ball motion is STONG and will read in the heaviest of oil patterns. When it exits the pattern it doesn't run out of gas like most big asym solids. The new Spec cover stock really helps this ball continue through the pins. • House Shot: The fresh cover is STRONG. And in my opinion need to be adjusted to play on your typical house shot. This thing needs oil, so if your intent is to use it in league then you will need to bring the cover up to at least 3000 to account for the lighter volume house condition. • 2019 PBA 41ft Marshall Holman oil: The heavier volume pattern is what I originally wanted this ball for and it did not let me down. I was able to move right into the track area and the balls strong cover and core read the midlane beautifully creating the exact shape that I needed for this pattern. Once the pattern started to break down I was able to move left with it and it not run out of gas as long as there was oil in the heads to keep it from hooking too early. Get this ball in your bag ASAP. You will not be disappointed. Bowl up a storm! #StormNation

    Crux Prime Layout 1: 50 x 5.5 x 30 Layout 2: 90 x 2 x 55 Info: PAP 4 5/16 x 1/4 up, Speed 16-17, Rev Rate 400 The Prime has the brand new SPEC solid cover wrapped around the Catalyst core. I have drilled 2 and I LOVE them both. The first was a pin up 50 x 5.5 x 30. This ball is super slow off the friction which makes it very readable and predictable. I didn't think a ball this slow would carry so well, but it does. I have thrown it on all kinds of patterns except super short and it looks good on almost everything. With as controllable and slow as my pin up is, I decided to drill a low flare 90 x 2 x 55. Normally, I only throw these layouts on short, hooking sport patterns to control the lane, much like urethane. This one is good in that setting but also handles hooking house patterns pretty well too. If you are in the market for a amazingly smooth, controllable piece, give this one a try! If you want an angular, downlane hook monster, this probably isn't the ball. If that is what you want, give the Physix a try. Chris Freeland Storm Amateur Staff

    Catalyst core, need I say more?? Since you asked.. If you need a ball for heavy oil, don't bother looking any further. I have never thrown a ball that literally just never stops. The deeper inside I get the better the ball reacts. I drilled mine pin up as anything drilled pin down for me is too strong on your THS. My first look with this on a sport pattern was nothing short of amazing. It allowed me to throw the ball more comfortably and not feel the need to manipulate ball roll with my hand or speed quite as much. Having a low/medium rev rate, manipulating the ball roll with such things is something I have grown accustomed to, so this was a nice change. Knowing how long the Crux Prime will be able to remain in my bag do to the new SPEC cover technology I am extremely excited, it's just an added bonus. Definitely a great fresh heavy oil ball for when my Physix just isn't quite enough.

    The new Crux Prime by Storm picked up right where the Alpha Crux left off giving Storm that dominate asymmetrical ball at the top of their line. Having never thrown the Alpha Crux or Sure Lock, I choose to Compare it too the Roto Idol Solid, the Crux Prime actually gives me a similar motion as Idol but in a stronger motion. If you loved any of the Crux's and especially the Alpha Crux, you will absolutely love this ball.

    Storm Crux Prime Layout: 55 x 4 5/8 x 55 The Crux Prime has surprised me, in that it has become of my favorite bowling balls that I have thrown in years. I did not expect this super strong high end ball to be as usable at it is. I did hit the ball lightly with some polish before using it, so that I could mimic the lane shine that would usually show up after 20-30 games. My intent with doing this was to conserve the energy through the front part of the lane better, which it did. This ball is still quite strong, even with the surface adjustment, but I have no qualms with moving left and circling the lane a bit when the lanes break down. Having said that – this ball is in no way at home on drier lanes, but as long as there is some oil in the front part of the lane, this ball is a treat. Out of box it could handle the heaviest of heavy oils. The midlane traction is very strong, but the ball continues through the pins very well. Amazing ball on anything medium oil or heavier!

    rev rate 537 -tilt 21- Rotation 59* - ball speed 17- rev dominate layout 80 x 3.5 x 45 no extra hole 757 out of the box with this gem. It is strong but a different type of motion for me. For me the shape was more rounded than my Physix and I had to keep my angles closed a bit more. It hits like a truck and keeps the pins extremely low which has increased the carry percentage for me. I have thrown it on a house shot, 50 foot sport pattern ,39 foot Masters pattern and the Original CHeetah pattern. it was great on House , Masters and Cheetah . on the 50 foot pattern i typically use pearls for more backend reaction so it didnt shape like I like on the 50 footer. The cover seems very durable and not an oil soaker. Ball will always have a place in my bag for sure Jim Wollschleger Storm Pro Shop Staff #STORMNATION

    Layout 52x4-3/16x59 pin in the ring PSA out about 2 inches. RPM 400 Axis tilt 10 degrees As someone who was disappointed in seeing the sure lock get retired, I was skeptical of this ball would replace it. The sure lock still has it's on motion but the new crux prime is much more versatile. The new SPEC cover has not given up after over a month of solid bowling. With an absorption rate vastly slower than other cover stocks I am not shocked to see the ball making the turn. A slower absorption rate means it will not need to have the oil removed nearly as often. For myself I was looking for this to be my ball for heavy oil, as one of the house shots I bowl on is heavily flooded. Only having 400 Revs I need all the help I can get. If you are looking for a good ball on heavy oil then you are looking for this ball. It is not a skid-flip motion however, it digs into the lane early reading the midlane with a smooth and continuous motion into the pocket. I believe this ball will be good for a lot of different bowling types as it is versatile and forgiving. I can say however I shot 300 and 800 my third set with it.

    The Crux Prime by Storm is hands down one of the first balls out of my bag for tournaments or anything with longer patterns. The all new SPEC coverstock (Storm Performance Enhanced Coverstock) is one of the strongest and most forgiving I have ever seen. This added with the proven Catalyst core make for a very heavy, smooth rolling ball. I matched this with my favorite layout of 60x5x40 (PAP 5 3/8 up 3/8) and was blown away. This ball not only looks amazing going down the lane but hits like a tank. With the way I have my arsenal set up my Physix (same Layout) is a perfect ball to ball down to. The Crux Prime just seems to get better and better the more games you have on it. Of course with any dull ball it is very important to make sure that you stay on top of your surface management. I already have another one coming and cannot wait to throw it with my favorite pin down layout.

    The Crux Prime is the latest high performance bowling ball in the premier line from Storm. The Prime uses the same Catalyst core that was in the previous Crux balls, but this time, wrapped with an all new to the industry cover stock formula called Spec. This new formula of solid reactive material produces a lot of hook, with less oil absorption than other formulas and comes from the factory with a 2000 grit abralon finish. In a nutshell, the Crux Prime is a big hook ball that is also built to last. The Prime has an Rg of 2.50 with a differential of 0.052, and intermediate diff of 0.017, in 15lb bowling balls. I drilled my Crux Prime using a 4 x 4 x 3 layout. Comparing the Prime to a Physix with a 4 x 5 x 3 layout, both balls were in their respective factory finish, although the Physix has about 35 games on it. I drilled the Prime and went to league the next night with an open mind and no expectations. I had been using the Physix, and been doing very well on this higher volume house condition, and posting a 300 with it a little bit back. I started with the Prime, which I had to move in about 3 & 2 with my feet/mark, to keep the ball holding pocket, compared to the Physix. All I could say was WOW! The Prime read the pattern perfectly for two games, posting a 279 and 245 without moving my feet. Then game 3, 168. I stayed in one spot WAY too long, and by the time I moved, I was playing catch up the rest of the game which turned into Splitsville. The next set I threw the Prime, I learned from my previous mistake of staying put. I decided to gradually move in with it as the 3 game set went on, shooting 258, 237, 278 for a 773. What I learned about the Prime, is that this ball will be a beast for me when I can use it in PBA where we move every game, and generally don't see as much traffic as the right side of the lane gets. When bowling on high traffic conditions, know when to move with it, or just put it away and grab something else. The Prime also rolled great for me on the 2012 PBA Detroit Open pattern that is 42 feet long, with total volume of 25.5ml. I was able to stay put for three games on this pattern, and not see that huge breakdown at the breakpoint like I saw on the league condition, posting blocks of 673, 653, and 664, on the fairly flat sport pattern. I polished the Prime with Storm step #1 to see how it rolled with less surface, and it looks great on USBC White pattern #2. In summary, the Crux Prime has a very unique ball motion. It takes changes to the cover very well, and doesn't seem to lane shine as quick as other super strong covers can. The biggest thing with the Prime, is to know when to make a move, or when to go to a different ball. The motion that it makes can sometimes trick a bowler into thinking they can stay in one spot longer, then they really should. This will be a great ball for bowlers who watch what is going on with the lanes throughout the night, but could possibly mislead a bowler who isn't watching for transition. Thank you for taking the time to read my review of the Crux Prime. As always, bowl up a Storm!

    My stats are in my profile. I laid the CRUX PRIME out 65x5x35. This is my preferred initial layout on big core asymmetric bowling balls. I have been touching the surface up with 2000 when it shows a little lane shine. For me I have mainly been throwing the PRIME on a sport condition league that is 45' this half. The PRIME can be very slow off the spot if I am lazy with my release. Compared to a PHYSIX that has 45x4x30 layout, the PRIME was slow at the point. I went ahead and put a balance hole 6 3/4" from my pin down the VAL. Different bowling ball with the balance hole. The PRIME is more responsive at the break point and can be a little sharp. The strong cover does let me play the hold on this longer pattern which is better for my game as I tend to miss left more than I do right. I have been balling down with either the PHYSIX or new RG HALO PEARL depending on how much we chop up the track with surfaced balls. Drill this one if you want a strong ball that responds to your grip pressure. If you hit it the PRIME will hook. If you lay off, the PRIME will stay online and be predictable. All in all, this should be a good sport shot type ball because it is controllable and does not naturally break loose at the end of the pattern even on the fresh unless you "get on it" at the bottom and make it hook sharply.

    The new Crux Prime with the Spec cover is so good!! This ball has a smooth and heavy roll motion that is controllable and continues through the pins. It is a heavy oil ball that can be used on multiple patterns from medium up to heavy oil. I've used the Crux Prime in a couple tournaments and have loved the motion I have seen so far. I am a high rev, higher speed player so I like to use balls that get in to a roll sooner and the Crux Prime is perfect for it especially on flatter patterns. This ball is a must have in the bag!!

    This ball has gotten a lot of hype due to the core inside and it has not been a disappointment. I went with a longer Pin from Pap than other Asymmetrical Solids (Halo, Sure Lock) which allows this ball to get through the front part of the lane and a little more angular than normal for me. This ball is a perfect replacement for the Alpha Crux but it does more than that ball. I see it tumble through the front but continue on the back which will be the perfect shape I want for flatter patterns. I have seen success with this ball with added shine but I have decided to keep mine at 2000 to compliment other pieces in my bag. Layout: 60 x 5 x 40

    PAP - 3 5/8 up 1 1/8 Speed - 16 Tilt - 17 RPM -400 Storm's new ball in the premier line is the Crux Prime. It comes with all new coverstock called SPEC with the same core that is in the Crux line - Catalyst. I drilled mine 5.25 x 4.5 x 4.5 pin down. For me the motion of the Prime is very strong overall. But for a solid ball it still gives me good backend motion and just keeps going through the pins. Some bowlers are comparing the Prime to the Alpha, but for me the Crux is 3-5 boards stronger. I think the Prime will be a very good choice for S/D at Nationals this year. I have drilled a lot of these balls for all types of styles with great results. Brian Watson Pro Shop Staff

    Storm Crux Prime Ball Review by PJ Haggerty If you need a ball for heavier oil conditions, the Crux Prime is the ball you need to drill. With the same engine as the Alpha Crux and a brand new coverstock (Spec), the Crux Prime is designed to dig in the mid-lane and not stop hooking. After drilling two of them, I've seen first hand it does exactly that. The first one I drilled is mapped out as 5 ½ x 5 x 60 @ 3000 with water. With that layout and surface, I've seen the response time get quicker. Since so much urethane is going down the lane these days, I think the Crux Prime can help by still going through the pins the right way. The second one I drilled is mapped out as 6 x 4 x 70 with a very tall pin above my bridge and the mass bias right by the thumb. I hit it with a 2000 pad and this layout gives me a very controllable and forward motion. My response time is slower on this ball, but it doesn't slow down through the pins. All in all, if you need a ball to fight through oil and dig in the mid-lane, the Crux Prime should be the next ball in your bag. #StormNation

    The Crux series has been very good to me. I've had all of the worldwide releases and one of the overseas releases. Each Crux I have has a very specific and distinct reaction. The covers are so diverse between them, I'm able to usually find one that works on many patterns. Enter the Crux Prime with the Spec cover. Same fantastic core, new coverstock. Used one of my go-to layouts for big asyms and have not been disappointed. I've used it on a variety of THS patterns in many houses and this cover may make it the most versatile of all worldwide releases (Crux series). Out of box, my reaction was great. It gave me the normal 'stand left throw right' look on most house patterns. This core rolls through the pins better than most for me. It just seems to match my game really well. As it began to lane shine, after about 15 games, it was getting additional length, so I started tweaking the shell to see what else I can get out of it. I've had it as low as 1000 and high as 3000, but have yet to shine it up. This iteration of the Crux rolls great like all of the series, but I believe the new Spec cover may last longer than the GI-16 or ERG covers from the previous releases. I'm going to continue to put games on this one and see how long that cover will last. Since drilling, I've carried this ball to every tournament that I've rolled and there aren't many times that I haven't been able to use it at some point. I'm going to enjoy rolling every game I can with this one.

    Layout: 15x5.5x45 Surface: Box Lane Condition: THS mediumvolume Lane Surface: Brunswick Anvilane Tester: Sabrina Average: 220 Dexterity: Right PAP: 4 9/16>, 3/8U I drilled up a Crux Prime for our fresh league shot. I chose this layout because of my high axis tilt and need a ball to help me read the fresh oil better. I have one more that will be drilled that will be used for tournaments. So far I am really liking what this ball gives me down the lane. I am able move my feet left during the 4 game set without losing carry. I used this ball during our Wednesday scratch league and had a good look the first game and a half when playing just inside 2nd arrow out to 7/8. As the lanes transitioned I moved into my "weak 10 zone" that I see with some of my other equipment. This is where the Crux Prime really shined! I continued to carry the deeper I got, which for me is not that usual. Overall, I am liking what this ball is giving me to start the night and end the night. It is not jerky down lane when it hits the dry. It is smooth in the front part of the lanes and gives a good back end motion down the lane. I can't wait to see what this ball will give me with tournaments! Sabrina Groves Round Holes No Grips Proshop Storm Advisory Staff www.stormbowling.com

    The Crux line has always been a favorite to me. With the release of the Crux Prime I was really excited to have this option back in my bag. I drilled mine 50 x 5 x 30 out the box this ball was super early for me. Changed the surface to 3,000 and allowed me to see better results! It's a nice step up from my Physix when I more ball in my hand. Great ball to add to your lineup if you're looking for a high performance ball!

    Orientation: Right Handed Rev Rate: 375 RPM Speed: 16-17 MPH PAP: 4 5/8 straight across Location: Enterprise Park Lanes, Springfield MO Pattern: High Volume THS Layout: 50, 5 ¼, 70 I really liked the Crux series, especially the Alpha, so I was ready for the Prime. For me the Crux Prime is the perfect update in the Crux series. The Alpha was a little strong and slow for me, I needed something a touch cleaner and more on the backend. The Crux Prime is PERFECT for that. The SPEC cover does roll like a solid but it gives me backend and angle I never thought I could get with a solid. I have no trouble using in during a set. It's early smooth enough that I can throw it on the fresh but it's definitely got enough backend for me to use it later in a league session. If you're a fan of the Crux series, this on is a no brainer.

    Storm CruxPrime Review Thank you for checking out our review of the new Storm CruxPrime. The Prime brings to us the return of the Catalyst asymmetric weight block which was popular in the original Crux line up from a few years ago. The cover, on the other hand, is brand new and team Utah calls it SPEC, which stands for Storm Performance Enhanced Coverstock. The goal behind this new cover is to increase durability and performance over the lifespan of the bowling ball. We all have drilled a bowling ball, used it for a few months and got to a point where we are wondering where the reaction went. SPEC was designed to combat the, maybe until now, unavoidable downward spiral of performance drop off. I suppose we will see in the upcoming months how SPEC holds up. I drilled two CruxPrime's for our review, the first is a five inch pin down with the PSA 3 inches from my axis and the second is a 4 inch pin up with the PSA five inches from my axis. I bowled on our challenge pattern which is 39 feet with a five to one ratio, we named this shot in the memory of my Grandfather Bud Callahan. He was tough and fair but had an easy going side that people loved. That explains this shot, a bit tough, very fair but, not too difficult to overcome. When I've tested on this pattern before I had to keep my angles pretty tight. Mind you, I have an average rev rate with a bit higher ball speed and lower-ish tilt. If you know about ball reaction with my type of stats than you know that I need some help at the breakpoint. Typically, I have to wait for the pattern to develop before I get comfortable with moving my target in. After rolling the CruxPrime for just a couple shots, I thought I put the wrong pattern out. I instantly had between three and five more boards to miss by and trust me, I miss often. The Prime never seemed to quit! The pin down was smooth with a round mid-lane roll and the pin up had a touch more quickness coming off the dry boards. I say a touch more because of how strong this SPEC cover is, both balls were reacting within feet of each other, the only noticeable difference that I could see and maybe I'm imagining it, was the pin up seemed to tip over faster. With that said, I liked the way the block went through the pins better on the pin down. In comparison to the PhysiX, which is my current favorite ball, both CruxPrimes are about three boards stronger overall. I have my PhysiX drilled like the pin up Prime and between the two, the Prime is around two or more feet earlier than the PhysiX. In closing I am excited to get the CruxPrime into the hands of my lower rev rate players. I can think of a few gals and guys who are going to love rolling this ball. I am planning to do a second video after release to see how Spec is holding up so, keep a look out for that. Again, thank you for your time! I am Fred Callahan of Callahan's Performance Bowling and Bowl-O-Rama in Ct. Go grab a CruxPrime from your local Storm VIP Pro-Shop and go bowl up a Storm!
