No more creaking!!

I've used it several times

Exactlt as described. Was able to move my dura ace ceankset onto the TT bike and don't have that annoying creaking anymore.


Will this fit a 1x11 sram crankset?


Will this work on new R2 and Ultegra 6800 crankset?


Will this fit/work on a 2015 AR5?

Yes, your frame fits BB30, just make sure you need the 24mm reducer.

How does it install? Are the bearings radial or angular-contact?
