Shimano Hollowtech (stages) crank arm to TruVativ crankset? FSA Gossamer?Adapter?...
So I have the following problem:
Bike 1: Road bike with Shimano Ultegra crankset (hollowtech) with my stages PM on the non-drive side (my "regular" bike)
Bike 2: Road bike with TruVativ Elita GXP GigaXpipe 30/39/52T (my trainer bike)
Bike 3: Road bike with FSA Gossamer (travel bike I use out west)
Anyone know if there is an adapter(s) so that I can swap the Stages PM crank arm between bikes? or do I need a new crankset (will I need to get a new BB as well)?
