Bottom bracket and compact chainset queiry
I am looking to go from a 53/39 chainset to a compact as quite frankly I'm push on hills. At the moment I have a 105 octolink but don't get a octolink compact 10spd. I have been looking at both shimano and sram but not sure on sram bbs. Is the gxp bb a standard English thread or not as it's going on a ribble frame?
