Have you been maxing out spinning on a 50T chainring? Are you getting so fast that your twitter handle should be "bigringpusher88?" If this sounds like a dilemma, it's not; you're just more awesome than ever and you're about to start dropping people like never before when you start pushing a new 53 x 39 Shimano Ultegra 6800 crankset. Like Shimano's pro-level offering Dura-ace 9000, this crankset uses the new 4-bolt spider which is compatible with compact rings or big rings--together with the lightweight tubular aluminum design and Hollowtech II spindle, this crankset is a great way to go race-level 11-speed, shave some weight, and not break the bank.
4-bolt spider BCD is the same for compact rings, so you can run any chainring combo you like
Lightweight tubular aluminum design is responsive and ultra strong
Hollowtech II spindle construction adds stiffness for better output
