I was really struggling with the Campagnolo 12s UT crankset on my frame. It wouldn't spin as freely as my other Shimano drivetrains and I honestly tried everything. The shims worked a treat, and your YT video about experimenting with different sized shims worked perfectly. Its spinning freely and there's no lateral play. Thanks so much for helping me solve this issue.
I will not hesitate to recommend this fix to my Campy friends.It does exactly what it says it will do by eliminating the WW. The only difference I discovered is that works better on the DS cup, after all that's the side the WW is on. I tried it the way the video suggests and it puts the crank too close to the chain stay.
Yes, it takes a bit more effort than just screwing everything together, but is it well worth it. Nice set of shims and good instructions.
I used this kit to accommodate for the inner ring of a 53/39t bottoming out on the chainstay - the frame builder hadn't dimpled the tube to account for this, so only a compact would clear. This shim kit allowed me to push the DS cup out by 0.5mm, allowing the standard Campy UT crank to clear. Perfect. Customer support was excellent: I asked about my particular problem and got a personal call to discuss it.
Shim Kit for Campagnolo Ultra Torque - English. I appreciated the video showing installation of the sims. It was very detailed and allowed me to get a perfect fit. The shims were carefully packed and labeled for ease of use. I would order again.
