Just a note of warning. I had no issues at all with the adapter cups when running with my UT compact chainset (which I rode on for the first couple of months as I was out in San Francisco (lots of hills) but found when I got home (less hills, more racing), I couldn't fit a standard (39/53) crank on there at all, the bolts on the back of the crank (specifically the "extra" one that goes through the crank arm) wouldn't clear the chainstay. Moots were (as always) fantastically helpful and sent me a replacement frame (some issue with the chainstays on early RSL's not being "squashed" enough I think) but even then the clearance was so tight it wasn't workable. In the end (again thanks Moots) the only way I could find to run a 11spd campag standard crank was to swap the frame again for a custom one with a standard threaded BB. (Other options may have been to run a Cannondale or SRAM crank with my campag groupset but I didn't really want to go that route). Even with the threaded BB, the clearance is tight, but the bike has been riding faultlessly for 6 months now and I cannot give high enough praise to Moots after sales service for sorting it out.
