Great product to effectively preload bearings
I put an older campag super record 11 crankset in a 2015 cannondale synapse carbon with a bb30a bottom bracket. There was some play. It rode alright, but was hard to keep a consistent chain line, so shifting was occasionally poor, and i got some creaking and clunking from time to time. I tried to come up with a solution from home bench, including pulling the bearing cups, and putting a 42mm inner diameter spacer between the cup and the frame (not a great idea).
Then I found this shim kit, ordered it, problem solved! After tinkering with different combinations, it turned out I had approx. 1.63mm of play to correct. No more inconsistent chain line. No more creaking or clunking. Great product, highly recommend! This bike is MUCH more pleasurable to ride now
I go the shims a few weeks back and waited to do my Biachi's overhaul. Cleaned up everything and started with a .75 mm shim. That worked fairly easy, but was a little too tight. Popped the crankset apart and put a .5 and .13. I was prepared to take the .13 out, but it was fine. The total time for assembly, disassembly and then torque took 15 minutes. Most of that time was to get the axle splines aligned and the binding bolt installed. Let's see how it does in a thousand miles.
These shims are essential at sucking up any excess gap between the mated UT cranks and the bottom bracket. No clunk, and perfect centerline set mean no noise. In my case no noise in any gear ratio. I highly recommend these if you are a campy addict
One of the .75 mm thick shims in the kit solved the Ultra-Torque clicking on the 2013 Bianchi Sempre that I commute back and forth to work on a couple of days a week.
Anyone who’s experienced the annoying Ultra-Torque click will easily fix the issue using the RougeMechanic’s Shim Kit!
