    Roto Grip Rubicon UC2 Cover Stock: eTrax Pearl Reactive Core: Rondure Core My review of the UC2 will be different than any other you will read. When the UC2 was released I was very happy with the mid-strength pearls in my arsenal and was worried about overlap, so I drilled my UC2 for very little flare. I drilled my UC2 60x5x50, looking for a urethane like roll with a little more punch through the pins. Long pin to pap layouts are similar to short pin to pap layouts for me. Anything 5" or more or 2" or less will have very little flare. With this layout, my UC2 looks just a touch stronger than my Fast Pitch...not what it was intended to do for most people but it's something I didn't have in the bag at the time. It's not for everyone but it is a useful situational ball for me.

    The new HP4 ball in the RG line is the Rubicon UC2. RG took the very successful Rubicon and added a pearl cover (eTrax-S20 Pearl Reactive). I drilled my with the standard pin up above fingers and MB an inch right of thumb. When first throwing the UC2 I was like wow a lot of backend reaction. Super clean and angular downlane. A "Quick Ball". On the fresh it was really too much down lane, where the UC2 shines is later in blocks or 2nd or 3rd game of league when the heads burn up a little. I have added a little surface to cover to help slow it down a little on sport patterns. Very popular balls with the PBA guys and league bowlers. Definitely a home run from the Schlem and Utah guys!

    I'm a big fan of the E-trax cover and could not wait to throw this beast. First love the colors on this ball really looks good going down the lane. Now lets talk about the ball motion really clean through the fronts really picks up mid lane and boy does it go on the backend and through the pins with authority. This ball def meet by expectations and I am loving it .. Grab one today you will not be disappointed

    Ball Specs Cover Stock: eTrax Pearl Reactive Finish: 1500 Grit Polished Core: Rondure Core RG: 2.49 Diff: 0.052 PSA: .011 Layout: 35 x 4 3/4 x 15 Drilled the same as my 900 Global HB Intensity and Revival, I was looking for the same shape but more snap. With the slightly lower rg and higher differential I could easily see more of an angular motion at the breakpoint than than the HBs. After 21 games I am able to use the UC2 more as a game 2 ball after the Intensity and before the Revival. I was pleased with the pearl covers performance during breakin period as pearls usually take a longer time for me to use consistently. Overall a very complimentary ball to the solid or first ball out the bag depending on your preference. Pick up one at your local VIP Proshop or 12 IN A ROW PROSHOP at JIB Lanes

    Rubicon UC2 - Ball Specs Cover Stock: eTrax Pearl Reactive Finish: 1500 Grit Polished Core: Rondure Core Layout: 65 x 4 1/4 x 40 RG: 2.49 Differential: 0.052 Intermediate Diff: .011 Review The HP3 line Rubicon UC2 has the Rondure Core which was developed to increase the ball's motion throughout the lane with the absence of the balance hole. The UC2 is very clean through the front part of the lane, reads the midlane well and turns the corner hard on the backend. As a mid to low rev player the UC2 eTrax Pearlized cover stock will flex its muscles during transition especially on longer house patterns to help get the corner pins out. I tested this ball on 44 feet typical house pattern with a lot of down lane transition. This ball will be in my bag for league and tournaments. This is a great ball for all levels of bowlers.

    I am a player that matches well with his rev rate (380) and speed (17mph) Sport average : 190 House shot : 220 Right handed - one handed Woah! This ball pretty much speaks for itself. I drilled this ball 45 x 4 1/2 x 45 with my PAP at 4 1/2 right and 1/2 up. Please if you don't understand these numbers, go to your pro shop operator and ask questions! This ball is very continuous for me once it finds friction. Very Responsive! Watching this go down the lane, if you are looking for the Skid- Snap (down the lane and then hook motion) this is it! I'll start around board 15 (3rd arrow) and get the ball down lane around 5-7th board. Bowlers who have a lot of hand and want to see the big hook, you will get it! A lot of hook, for a mid performance ball.

    LANE CONDITION Length:41 Volume:Medium Type (THS, Sport Pattern etc):THS COMMENTS Core: Rondure Cover: eTrax-S20 Pearl Finish: 1500 Polish RG: 2.49 Diff: 0.052 The Rubicon UC2 is everything I expected and then some. For me the UC2 will be a great THS ball or a later in the day tournament ball. Its so clean down the lane, but once it hits the friction it just goes. The backend reaction is really where this ball shines, as you can just keep moving left with your feet, the ball drives harder and harder off the dry. I was a little worried that for me this ball would go to long before making the turn, and leaving a lot of corner pins, that was not the case. The pin action is something that is most impressive with the UC2. This is a ball that will be in the bag for a long time.

    Roto Grip Rubicon UC - e-TRAX pearl coversotck - Rondure Core 1500ab grit with factory polish - layout 55 x 2 1/2 x 55 The next step in ball motion is here - the Roto Grip Rubicon UC2. The Rondure core is a edgy core design, making the core asymmetrical, but very close to a symmetrical after drilling. On mine Bret at Bowlers' Supply laid it out to miss a majority of the spikes on the core to keep the integrity of the core in place. Even with short pin layout, the ball still went down farther down lane then the Roto Grip Idol Synergy and the Nuclear Cell with longer pin layouts. The "wobble" that the ball produces allows it to pack a powerful punch off of the dry and packs power through the pin deck. Used the ball on older HPL with a 44ft THS with a HUGE amount of volume and the ball rode through the front part of the pattern like a ninja sword slicing through watermelons. Best additional for a step up from the RST X-1 and the Idol Synergy. Thanks to Bowlers' Supply, Inc and Vise Inserts for their continued support and teaching more about this awesome game of bowling!!! #SquadRG #3Gshoes

    Ball Specs: Roto Grip Rubicon UC2 Coverstock: 1500 Polished eTrax™ Pearl Reactive Weight Block: Rondure™ Core (Asymmetrical) Color: Cosmic Black/Purple Sky Review: The Rubicon UC2 continues the greatness of the Rubicon line giving you a ball to transition to as the lanes change. Because of this, you see a lot of seasoned veterans and tournament bowlers transitioning to this piece deep in a block. For the average league bowler or someone looking to expand their bag, the price point offers a look into strong backend motion with incredible continuation. Overall, this ball is a very versatile piece of equipment and there is no doubt you will be seeing a lot of purple and black on TV.

    Rubicon UC2 Versatile – Motion – Controllable These are the three words that comes to mind to me when I think about how the Rubicon UC2 rolls for me. Versatile because I can play straight down 10 board or if I need to open my angles I can play left and somewhere around 20 board out to 5 and still have the hitting power through the pocket. Motion of this ball is crazy! Everyone I know compares this ball to the Idol Pearl and I loved that ball which made this choice a no brainer. Controllable is the last word I would say about this ball because even with the snap and quick turn off the spot this ball has it is constant and predictable. Highly recommend if you want a ball that is going to move more in the backend and if you are looking for a ball that help you open your angles.

    The Roto Grip Rubicon UC2 is the Pearl Compliment To the Solid Rubicon, Although i did not have a chance to throw the original Rubicon i can see why the reviews were outstanding on it. This Ball Reminds me of the old school Storm/Roto Reaction, this ball Really Corners hard down lane and has recovery for Days. When i need to get left and throw it right this is my go to ball. This ball is perfect for when the lanes break down a bit as it glides down the lane effortlessly.

    Rubicon UC2 The Rubicon UC2 is a pearl small asymmetric ball (cores with low intermediate differential) and pearl version of the original Rubicon solid. First blush is that the UC2 is amazing, and it is already making BIG waves on the PBA tour and in leagues throughout the country. The Rubicon UC2 out of box is very clean and because of the low int. diff. is a med-med/fast response reaction down lane. I am really impressed with how versatile the UC2 is for as clean and responsive it is.

    The Rubicon UC2 is the pearlized version of the ever popular Roto Grip Rubicon. The cosmic black/purple sky color eTrax pearl cover has an old school type color combination, but brings it to a modern era and feel with the bright pink lettering. The 15lb Rubicon UC2 numbers are 2.49 Rg, 0.052 diff, and 0.011 intermediate diff. The UC2 uses the same Rondure core as with the solid Rubicon. The Rondure core was designed by Roto Grip based on the new USBC no balance hole rule to give bowlers the reaction shape of a symmetrical bowling ball with a balance hole (that alters the core shape and final drill numbers), making it stronger than the same ball drilled without an extra hole. This helps bridge the gap between symmetrical, and big asymmetrical bowling balls. I drilled the UC2 with a 4.5 X 3 X 4 layout, the same as my pin down Rubicon. Comparing the two balls in the respective box finishes, the UC2 clears the fronts and mids much easier by a few feet, and has a much more defined change of direction. The overall board coverage of the UC2 is a few boards less than the solid version, both in their respective box finishes. I polished my Rubicon with Storm step #2, to the same 1500 grit finish as the UC2 for comparison. With the Rubicon polished, the UC2 still has a much more defined breakpoint, and out hooks the polished Rubicon by a few boards. The UC2 finds the perfect line of being controllable and just on the verge of (without being too skid-flippy) a hockey stick type reaction. The UC2 likes some friction on the lane to help it slow down and go through the pins the right way. As always, a little surface can help with controlling when the UC2 wants to slow down, to produce the right amount of roll through the pins. I like the UC2. Not only is it a great looking ball, the reaction shape is very usable for most conditions that have some friction to throw to. There would be a place in any bowlers bag to have both a Rubicon and the new UC2, with no overlap. The differences of the two are great enough, that I could see a hybrid version possibly coming to market, at least that would be my wishful thinking. Stop by your local certified pro shop, and drill a Rubicon UC2, and OWN IT!

    Roto Grip Rubicon UC2 Bowlers Info: RH tweener, PAP 4-1/2 x 7/8 up, 365 RPM, 17* of Axis tilt, 60* of Axis Rotation Ball Layout: 50 x 5.5 x 50 Finish: OOB For anyone that has enjoyed success with the Rubicon and the Halo Pearl, you will really like the UC2!!! I drilled this similar to my old Halo Pearl wich was a 5.5" pin over middle finger and PSA kicked right. For me, the UC2 is very skid/flip motion, cleaner than the Halo Pearl was but generally quicker off the spot. I can see using this in the later games where my angles need to get steep and I need the quick recovery. Amazing piece that allows me to open up the lane and tear 'em up!!!

    Orientation: Right Handed Rev Rate: 400 RPM Speed: 16-17 MPH PAP: 4 ½ over and ½ up Location: Enterprise Park Lanes, Springfield MO Pattern: High Volume THS VLS Layout: 5 x 4 x 2 1/2 Dual Angle Layout: 50 x 5 x 40 The UC2 is the pearl version of the OG Rubicon and the pearl mild asym replacement for the Idol Pearl. It's amazing. It's exactly what I wanted this ball to be. It's clean, hits the midlane plenty but not so much that it stops like the BIG asyms. I have a pin down one that I throw a ton and I can throw it on the fresh and get in quite a bit before switching. It acts an awful lot like my pin down Idol Pearl with a weight hole that I threw on everything and loved. The UC2 is a must have from Roto Grip.

    The Roto Grip Rubicon UC2 is the ball to get if you like the Rubicon but need more length and backend. This HP3 line ball is an asymmetric that feels like an HP4 line ball. It skids nicely through the heads when there is oil like on fresh and delivers a strong backend motion. Just make sure you have some head oil or it will start a little early and be super strong on the backend. It reminds me of the Idol Pearl just stronger overall. It will jump off the dry as most reactive pearls should and will do. It's great compliment to the Rubicon. Hitting Power is great like every Roto Grip Ball I've thrown. I can play pretty much any line but it seems best around 3rd to 4th arrow. Any deeper in the oil ill need to slow the ball speed for it to pick up if I don't pitch it to the dry. My PAP is 5-1/8 and 1/8 up. Usually around 15-16mph, I'd probably be classified between a tweener and a cranker. I drilled this one 5.5x4x2 See my ball review video on YouTube here: https://www.youtube.com/watch?v=Yh336yW4Uyc

    Roto Grip Rubicon UC2 Ball Specs: Cover stock Etrax Pearl Reactive Rondure Core (Asymmetrical) Color Dark Purple Finish 1500-grit Polished Bowler Specs: Right Hand. PAP 5" Over 1/2 up Rev Rate 300. Tilt 20. Rotation 50. Speed at cameras 15.5 Review: The Roto Grip Rubicon UC2 has been very popular at our shop. We did a Matchmaker Ball Demo and sold a good number of these balls. The UC2 gives a ball motion most bowlers are looking for. It is clean enough through the front with a very nice angular move to the pocket. I feel that Roto has created an Asymmetric ball that does not read too early and we are getting balance hole fine tuning without the use of the now banned extra hole. I have been really impressed with how this ball can master a house shot but is strong enough when you are playing a flatter more heavily oiled pattern. The Rubicon UC2 has plenty of bite in it for traction. The UC2 is stronger in reaction than my Trend but just a bit weaker than my Nuclear Cell. This is probably due to my Nuclear having a stronger mass bias. I did have a bit of trouble leaving ring 10's when I first rolled the UC2 on our house shot but after a teammate suggested I slow it down a bit the ball seemed to carry everything. This effect could also, I feel be achieved by hitting it with a 2000 or 3000 pad. I used to be uncomfortable sanding pearl balls but over the last 6 months or so I adjust with no worries because I feel the new covers are so good and made for adjustments. I can trust this ball to come back if I miss to the outside. On a lot of the newer Asymmetric balls I am drilling the Mass Bias closer to the thumb but on the Rubicon UC2 I have put the Mass Bias next to the thumb or out on the VAL with great success. I feel this ball will be a strong seller for Roto Grip. Summary: The UC2 is a very strong pearl with control. The entry angle and hit are very good. The surface takes adjustments easily for fine tuning. Video Link: https://youtu.be/ZiJr1sJd_t8 Glenn Wendel PBA Member Storm Pro Shop Staff gwendel@comcast.net www.stormbowling.com

    IM GOING TO SAY IT NOW!!! BALL OF THE YEAR!!! Ladies and gentlemen, Roto Grip has hit a home run with this release; Rubicon UC2. Same core featured in the original Rubicon with the Idol Pearl Coverstock. By far the best asymmetrical pearl bowling ball I have ever thrown hands down! If you need a ball that's clean through the front part of the lane with some serious angle downlane, this is the ball to have in your bag. I was very surprised at first at how much angle this ball creates off of the friction and it really burns up and goes forward, like the usual asym bowling ball shape. I can stay right and throw this ball hard or I can get in and create a ton of shape with this piece. Either way, this ball sends pins flying. In a three-month span, I have 4 300's and 3 800's with this ball. I cant say enough good things about this ball. Only thing left to say is get your as soon as possible at your local storm vip proshop if you want to keep up with the competition.

    First, some stats about me. I am a medium speed (15-16 MPH) player and slightly rev dominant. Last I checked, rev rate around 380 RPM. My A game is playing the middle part of the lane on a house pattern (between 15 and 20 at the arrows) but do not have a problem moving to either extreme if the pattern calls for it. My PAP is 4 7/16 over by 5/16 up. The layout used on the ball is a 40 x 4 3/8 x 20. I wanted a piece in my bag that was effortless through the front but plenty of engine downlane for a sharp backend reaction. It has a 1500 Grit polished finish on the eTrax pearl reactive coverstock. I'm a big fan of darker color bowling balls going down the lane so I was very excited to try this one out. The lane surface at my home house, Port Huron Lanes in Port Huron, MI, is Brunswick ProLane with a 42' house oil pattern. For the house pattern, I always start with my feet on 25 and just aim at 15 to get the ball to 6-7 at the break point. I drilled this ball with the idea that it would get plenty of use when I need to get steep with my launch angle and this ball definitely fits the bill. On the fresh, this ball reads the end of the pattern very aggressively so I do not think it will get much play until the lane breaks down a bit. In game 3 of a standard 5 man league, I was able to stand on 40, hit 17-18 at the arrows, go out to the dry and watch it boomerang back. If you need something to help get you through the front part of the lane, this shiny coverstock does that effortlessly and the strong core all but guarantees that it will read the end of the pattern properly. Very reliable and a perfect compliment to the original Rubicon!

    Ball Specs Rubicon UC2 Cover: 1500 grit polished, eTrax Pearl Reactive Weight Block: Roundure Core (Asymmetric) Color: Cosmic Black/Purple Sky Review: I never had the opportunity to the original Rubicon but after throwing the Rubicon UC2 I can see why the original Rubicon was like so much. I drilled my Rubicon UC2 pin down with the purpose of using it on our house shot for league. This ball did not disappoint in anyway. It was clean though the fronts and gave me a nice mid lane reaction while storing all of it's energy for when it hit the pins. I see the ball not only performing well on the typical house shot by also managing to make it's way into my tournament bags for when I need a reliable ball that I can trust will not over react on me when I need something controllable. This was another fantastic bowling ball put out by Roto Grip. If you haven't already picked yours up I wouldn't highly suggest you making sure you get yours sooner rather then later because you will not regret it.

    The Rubicon UC2 is one special ball I really liked the original Rubicon so when i seen this got releases I couldn't be more excited. I always tend to gravitate to Pearl reactive cover stocks mainly letting me play straighter for longer. More of my comfort zone for sure if I can stay playing 2/3 arrow I will have good sets in league. The UC2 for me is about 3 boards weaker then the OG Rubicon but obviously much different shape for sure. OG is super slow and controllable as the UC2 is more skid flip for me.

    Layout: 40 x 4 3/16 x 35 Similar to how I could not put down the Idol Synergy as soon as I drilled it, the same thing has happened with the Rubicon UC2 – I have hardly thrown any other ball since I put holes in this purple beauty. It is super clean in the fronts but has a good bit of midlane traction to go with the strong backend that it possesses. I purposely drilled this ball with a stronger layout than I normally would, to make sure that the ball would not be too skid-flip. What I am left with is a strong arcing pearl ball that I can use on anything from medium-heavy to medium-dry lanes, with a ton of energy left when it goes through the pins. As you'd likely guess, the original sanded Rubicon is a perfect ball to use when the lanes are too oily for the UC2.

    Core: Rondure Cover: eTrax-S20 Pearl Finish: 1500 Polish RG: 2.49 Diff: 0.052 ME: Right-Handed Tweener Speed: 12-13 mph Rev Rate: 315 PAP: 4 7/8 Right 3/8 Up Ball Layout: Pin over ring 55 X 4 1/2 X 30 The Roto Grip Rubicon UC2 is the latest release in Roto's' HP3 performance line. The Rondure core that was so popular in the original Rubicon has this time been wrapped in the very clean etrax pearl cover. A clean coverstock combined with a powerhouse asymmetric core has a predictable result. Power off the friction. The UC2 is the quickest ball for me in the current SPI line-up. When it sees the friction, IT GOES. I first threw it on a broken down house shot. I had taken the time to watch a few of the staffers who got it before me and was excited to see it move. The first couple of shots were quick but not what I'd expected. I was confused until I threw my hy-road pearl in the same spot and watched it barely wiggle when it hit the back-end. There was so much carry-down on the pair I was amazed that the UC2 had been coming back. I didn't take it out again until the second game of league that week. I started to see my earlier ball slow down too much so I figured I'd give the UC2 a shot. I moved a few left and completely lost the ball off my hand. As I put my hands up to say oh no, the ball peeled back and ran over the 8 pin. Our house shot is pretty cliffed but I had no expectation of the ball hitting the head-pin. As a result my next shot I moved another 5 left and made a better shot. The angle this ball creates when going around the lane is fantastic. This ball is perfected designed to compliment the original rubicon. It's the skid/flip motion for newer lane patterns and e-trax was a great choice for cover. As a pro shop operator its always important to have these down-lane hook monsters available for the bowlers who judge ball strength by what the ball does in the back end.

    introducing the newest addition to the HP3 Line the brand new Roto Grip Rubicon UC2! The brand new Rubicon UC2 is the Pearl version of the Rubicon! The Rubicon UC2 features the eTrax Pearl Reactive Coverstock wrapped around the Roudure Core which was previously seen in the Rubicon! The Rubicon UC2 is very clean throughout the front and, mid part of the lane with a very smooth continuous motion on the backend which is unique for a shiny pearl ball! The Rubicon UC2 will come in handy for when I need to clear the front, mid part of the lane and, will be a good compliment to the Rubicon for when it starts to hook to early. The UC2 is a must for anyone and, found a spot in my bag immediately!

  • Roto Grip Rubicon UC2 review by Mike Craig

    Posted by Roto Grip Rubicon UC2 review by Mike Craig on Mar 7th 2021

    I drilled my RUBICON UC2 up 60 x 4.5 x 30. I have thrown it at box finish which is polished and also hit it with a 2000 pad lightly. The intent was to have a cleaner cover version of the RUBICON in my bag for when the RUBICON started to slow down or get lazy at the spot. I have thrown the UC2 on mostly house as it came out right after the holidays when tournament play slowed down here in Ohio. On house it is nice to pull out when the dry starts to get sharp and my ZEN and AXIOM PEARL are getting to be too much off the spot. The UC2 is smoother than both of those and is a good compliment to sequence off of either of those balls. Drill the UC2 up to get a cleaner option when the typical first stronger pearls out of the bag are too much and it is too early to go to the weaker core pearls.
