Rogue Mechanic Shim Kit for Campagnolo Ultra-Torque Bottom Brackets- English

3 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.

Amazing magical shims

If your Campagnolo bottom bracket is creaking along like a mother-in-law, these shims are an absolute must have. Why suffer with every revolution and needlessly destroy cups and bearings? Order now and quality, silent, smooth riding is on the way to your door step.

Excellent quality & service

Ultra Torque shims were of high quality. A little spendy but worth every penny. My order shipped immediately and arrived in perfect condition.

Well designed product!

This ultra torque shim kit works exactly as it should. It eliminated the wave washer that campy designed and sets the bearings up properly with just enough preload. This is how campagnolo should have designed the ultra torque in the first place! My bottom bracket now turns quietly even under heavy load like an out-of-the-saddle steep climb. I am very happy with this product!

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

This shim kit is very high quality and well made. The shim kit instructional videos provided by John on the RogueMechanic web site were exceptionally detailed and helpful!

I have used the Campagnolo ultra torque crank/bottom bracket system on my road bike for many years with no issues. Recently, I noticed a slight, intermittent clicking noise coming from the bottom bracket when climbing. I decided to replace the wave washer, the old washer appeared to be worn, re-greased the bottom bracket cups, and the noise went away.

In the event the clicking returns, I will use the shim kit to eliminate the pre-load provided by the wave washer. This option seems to be a great permanent solution to remedy potential noise issues associated with the ultra torque system!
