Putting the power to the pavement: the stiff, smooth, and strong SRAM Red Crankset is poised to dominate. Fatigue, flex, and friction, enemies all, and they'll rob you of speed and performance over both the short and the long hauls. The SRAM Red Crankset does its part to keep them from affecting your ride. The integrated carbon spider's design is lightweight and extremely stiff, allowing for instant, efficient power transfer. The Red Crankset virtually eliminates it with new hybrid ceramic bearings housed within the GXP™BB's case. Ceramic bearings ride in a stainless steel race, are more efficient, use a lighter seal, and are lighter, stiffer, and longer-lasting than normal bearings. Red PowerGlide™ chainrings are designed to professional-grade shift, stiffness, and durability standards. English threaded cups only.

VumaQuad Bottom Bracket sold separately

Zipp's new bonding system yields a featherweight crankset capable of passing the rigorous new CEN crankset fatigue standard. The four-arm spider integrates the fourth chainring bolt into the crankarm for improved stiffness. NoNuts chainring bolts eliminate the inner chainring bolt for a more positive chainring/crankarm interface. 30mm aluminum axle spindle rides on precision Grade 10 hardened bearings. Includes crankset, standard bottom bracket and installation tool. 110mm bolt circle.
