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!
