Sure your bike’s one curvy, confident, carbon beast—but don’t expect that same arrogance when it sees you pull a new Shimano Ultegra FC-6700 Crankset out of the box. Once you slide the stupidly stiff axle into a free-spinning bottom bracket, this Ultegra crankset will become your bike’s new focal point. We all learned in kindergarten that what really counts is what’s on the inside—still true, and in Shimano’s case it’s nothing. Using the same mind-blowing Hollowtech chainring construction as Dura-ace, the dead-sexy Ultegra shares the insane stiffness-to-weight ratio and crispy shifts as its higher-end sibling—without the mind-blowing cost.
