SRAM Apex 50-34T Road Bike Crankset with GXP Bottom Bracket - Lightweight Performance Chainset for Road Cycling, Commuting & Endurance Rides

I purchased 3 of these to replace the 53/39 cranks on my bikes. The GPX BB fits the 68mm shell perfectly and sets up the crank with a perfect chain line. There is very little deflection even under significant force such as standing to climb in a higher gear. Because it spins true, front derailleur rub is not present except for when on the 39 with the smallest gear on the cog (you should not be in that gear anyway). I have tested with both 10 spd SRAM and 9 spd Shimano chains, no issues shifting in either case. My average review score on bike components is about 3 Stars, I am not an easy grader, this is a great component and reasonably priced. I have SRAM Force on my Carbon Frame bike, this works just as well, just a slightly higher mass.
