Shimano 2010 Ultegra FC 6700 Road Bicycle Double Crank Set

Sure your bikes one curvy, confident, carbon beastbut dont 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 bikes new attention whore. We all learned in kindergarten that what really counts is whats on the insidestill true, and in Shimanos case its 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 siblingwithout the mind-blowing cost.Product Features: margin-left: 25px;"Material: [Arms] Aluminum; [Ring(s)] steal; [Spindle]steal; [Bolts] AluminumArm Length: 170mm (include if not an option)Gear Ratio:[Crank Arm Length] 39 x 53TBottom Bracket: IncludedBB Type/Threading: External Bolt Circle Diameter: 130mmWeight: [no BB, 170mm] 1.56lbs (706g) Recommended Use: Road cyclingManufacturer Warranty: 2 Years
