Roto Grip is doing something different with the Rubicon upper-mid performance balls in their HP3 line of balls. Like the original Rubicon the Rubicon UC2 (Ultimate Concept 2) uses the asymmetrical Rondure Core which was designed to provide more ball motion overall without the need for the now-banned balance hole. This performance core is wrapped in Roto Grip's eTrax-S20 Pearl Reactive coverstock which was formulated to offer a response on various lane conditions due to its ability to clear the lane then react powerfully on the backend. Out of the box this ball is ideally used on medium to medium/heavy oil conditions.

Color: Cosmic Black/Purple Sky
All colors do vary somewhat from the picture shown
Core: Rondure Core (Asymmetrical) (14-16#)
Coverstock: eTrax-S20 Pearl Reactive
Finish: 1500-grit Polished
RG: 2.49 (for 15# ball)
Differential: 0.052 (for 15# ball)
Recommended Lane Condition: Medium to Medium/Heavy

Roto Grip Rubicon UC2 review by Trevor Roberts

Lane Condition
Length: 40
Volume: Medium
Type (THS, Sport Pattern etc): THS

After drilling two Rubicons, I was very excited for the pearl version, the Rubicon UC2. I just threw it for the first time yesterday and I’m already impressed by the motion. The cover is even cleaner than I thought it would be, giving me a nice compliment to the Nuclear Cell. In my YouTube ball review you will see how the Rubicon UC2 is a little bit cleaner through the fronts than the Nuclear Cell, giving it a sharper down lane motion. This ball will be great for house shots and for any time you need to move left with your feet. Oh and have you seen the colors of this ball? The pink lettering on top of the shiny, dark cover looks great! I might have two or three of these, it’s that good!

The Roto Grip Rubicon UC2 brings a shiny pearl version of the original Rubicon to the line, and it's everything you expect and then some! An updated version of eTrax Pearl (Idol Pearl, Halo Pearl) with the same mildly-asymmetric Rondure core from the original Rubicon. The overall shape feels very reminiscent of the original Rubicon just getting further down the lane and turning harder once it sees friction - which also brings it to feel VERY familiar to the legendary Code Black from the Storm catalog. It's a great skid-flip piece for later in a block that brings a lot more control to the picture than most balls in the category, and mine is a permanent fixture in my travel bag!

Cover: eTrax Reactive Pearl
RG: 2.49
PSA: 0.011

This ball is awesome!! I liked the Rubicon Solid a lot when it was released. However, I have been looking for a pearl ball with this ball motion since I switched companies. This ball was a pleasant surprise for me. The layout is 60 X 3 ¼ x 45. The UC2 is cleaner down lane and picks up and drives through the pocket. I was surprised how well it blended out the house shot I bowl on when the lanes broke down. When others were leaving corner pins, I was carrying the pocket and the ball was still getting through the pins. I can create shape with the UC2 and trust it will turn the corner. I did hit it with 3000 which made it a bit smoother and doesn’t’ jump of the friction. Lately this has been the first ball out of the bag!! I highly recommend the UC2 if you are looking for that stronger Asymmetrical ball that will fit pretty much all styles of play you won’t be disappointed.

The Rubicon UC2 features the etrax pearl cover and mild asymmetric Rondure core.  The eTrax formula has been used in several iterations in the HP3 and HP4 lines over the last few years, and this version of the formula is the pearl version of the Idol Synergy cover.  The Rondure core comes in at a 2.49 RG, .052 differential, and .011 split or intermediate differential in 15 pounds, the idea again being to mimic a stronger symmetric ball with a weight hole.  The original Rubicon was already pretty quick on friction despite being a solid, with the cleaner eTrax base formula on it, it definitely punched a lot, and the UC2 takes that up to 9000.  It’s very quick on friction and very easily controlled and manipulated with physical adjustments, I can play virtually anywhere I want to with this ball as you’ll see here in a few seconds.  It’s becoming a favorite of both Angel and mine because it’s very easy down the lane and turns quickly on friction, while being a lot more consistent than you might expect it to be.  It gets easy length for Angel and more punch than she gets out of literally anything else in her bag, and for me it’s something I can float out of and still get a sharp and visually comfortable move on the backend.  In addition, if I need to get deep, there are no angles it won’t recover from, at least if you’re on the right conditions for it.  The Rubicon UC2 is a ton of fun, it’s moved its way into both of our main league bags, and paired with the Rubicon, they’re a pretty devastating combo.  I give the Rubicon UC2 a 7 for hook, 7 for length, and a 9 for backend strength.

Roto Grip continues cultivating innovation with the release of the Rubicon UC2 (Ultimate Concepts 2). The mildly asymmetric Rondure core combined with the latest eTrax (Enhanced Traction) pearlized coverstock makes the Rubicon UC2 a pin crushing monster for your arsenal. Let’s take a look!
The “mildly” asymmetric Rondure core introduced with the Rubicon is a game changer for a straighter and more down and in player like me.  I found “mildly” asymmetric to mean the best of two cores in one, if you will.  This core rev’d early in the mid-lane with the precision of a symmetric core and simply continued to roll like a freight train down lane! Starting from fresh oil straight up 7, to after the transition where I was able to look 15, the Rondure core was impressive all night.  This hard rolling asymmetric core explodes at the pocket and maintains a strong continuation through the pins regardless of entry angle and keeps rolling its way through the pin-deck.
The eTrax Pearlized coverstock completes the UC2 quite nicely. Out of the box, the 1500 grit polished surface performed smoothly all night. On fresh oil, the cover cleared the heads easily and maintained a strong turn off the pattern.  The eTrax pearl cover read the mid-lane section throughout the night with a smooth and predictable motion and stayed consistent.  As the shot broke down I appreciated this cover’s ability to blend the deteriorating condition without “jumping” off the spot. I found the eTrax “pearl reactive cover” to be exactly as written. It’s a pearl but it is reactive!
In closing, I found the Rubicon UC2 to be a hard-hitting, strong rolling weapon! If you’re a more down and in player like me who counts on that extra hitting power, look no further. This ball is the right choice! The Rubicon UC2 belongs in your bag! Have your local pro shop operator drill yours up today!

UC2 will be 1 if those balls that stays around for a long time. It's that good and that useable. The ease it gets threw the front with along with it's strong recovery will not only make it into everyone's league bag but it will also be a must for tournaments. The ball is not only useable but it's fantastic from many different angles. You can't ask for much more!

Roto Grip Rubicon UC2

Rev Rate: 325 rpm, 7 degree of axis tilt, 40 degree of axis rotation
Testing information: 41 foot THS (medium to light volume)
Bowling Center: Fulton Bowling Center

The Roto Grip Rubicon UC2 utilizes the Rondure Core and newly formulated eTrax pearl coverstock. Wow! What a clean ball through the fronts then a big back end motion.  The backend recovery is really impressive.  The UC2 will be a house shot wrecker and one of your first options if you need to move left and throw it to the right.  The UC2 is already becoming a favorite on the PBA tour. A great color scheme just adds to its appeal.

Rubicon UC2
Layout - 55 x 5 x 30

Holy smokes this ball in impressive!  Super clean thru the front and all the backend you'd ever want.  I was not one that matched up well with the Idol Pearl and feel I've been missing that ball in my bag.  Boy is this one a home run!  Great looking ball, super versatile cover, don't be afraid to knock the shine off if you want to smooth it out a bit.  I've drilled one pin up and one pin down and both are very usable!  I would say its cleaner and longer than a Zen and Nuclear Cell.  If you are looking for a phenomenal all purpose ball, look no further!  She good!

Length: 42ft.

Volume: medium

Type (THS, Sport Pattern etc): THS


Likes:  The Rubicon UC2 is one of the strongest Pearl balls I have personally ever thrown!!!! It complements its predecessor very well. Where the original Rubicon was the typical smooth solid shape the UC2 gives you that easy length with a strong change of direction down lane. I compared the UC2 to a couple other pearl asym balls, the Nuclear Cell and AstroPhysix. To me, the UC2 is a combination of both of those 2. I get the length of the Astro but with the strong change of direction of the Nuclear. For the typical league pattern, the UC2 will allow you to play in the oil and feed the ball to the friction without worrying about the ball not finishing. I didnt have to force the ball up the lane as it just floats through the fronts and middle part of the lane with ease. This is going to be a very popular ball for all types of bowlers and will be a must have in your league and tournament bag.

After throwing this ball instantly knew that this was going to be a must in the bag. For being an asymmetrical bowling ball this ball gets straight through the fronts and has pop off the spot. The ball reacts more like a symmetrical then an asymmetrical bowling ball. The UC2 is a house shot monster. Great for fresh or if you need to move in and open your angles it will be very versatile to play on the burn. Visit your local pro shop and grab one of the best balls out on the market today!

Roto Grip Rubicon UC2 Ball Review by PJ Haggerty

The Roto Grip Rubicon UC2 is the newest addition to the HP3 line and I LOVE it.  I’m a big fan of the original Rubicon and when a pearl version was released, I was pumped to be able to throw it.  The UC2 provides numbers of 2.49 and .052, respectively.  Along with a pearl coverstock, the UC2 is a clean, quick-responsive, asymmetrical ball that is a perfect addition to the current lineup of equipment. 

I’ve only needed to drill one UC2 and I think it’s a home run.  When the original Rubicon starts to bog down and I need to open my angles with a quick response time, the UC2 is a perfect ball to go to.  Also, I’ve had the most success with the UC2 on medium-longer patterns.  The RG suggests it should be very good on those types of patterns with higher amounts of volume too.  Lastly, when patterns blend and break down, the UC2 is a perfect ball to go right-to-left with a quick response time. 

If you need a ball that does the right thing when you need it, especially if you need to cover some boards, the Rubicon UC2 could be a perfect fit!

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.

Type (THS, Sport Pattern etc):THS


Core: Rondure
Cover: eTrax-S20 Pearl
Finish: 1500 Polish
RG: 2.49
Diff: 0.052

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!
