RogueMechanic Shim Kit for Campagnolo Ultra-Torque Bottom Brackets- English

2 items left

This is the RogueMechanic Shim Kit made to solve the problem of axial movement in Campagnolo Ultra-Torque bottom bracket systems.  This movement sometimes manifests into noise in the form of clicking and/or knocking.  This side-to-side movement also accelerates the wear of components.  This shim kit is machined here in the Cleveland area from high-quality, US-made 18-8 stainless steel with the help of my father-in-law.  The shim kit has a total of eight shims (four different thicknesses) so that you can precisely dial in the correct stack height.   

This set of shims is specifically made for BSA/English threaded bottom brackets.

Here's a video explaining the installation process.

Worked beautifully!

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.

Works as advertised!

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.

Fixes Campy's Poor BB Design

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.

Michael Kuredjian (San Francisco, US)

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.
