evo.com | SRAM Crank Sets > The SRAM X01 Eagle Crankset is not only likely lighter than what you're riding, but it's likely stronger too. By only putting material where it'll add strength, SRAM have created a carbon crankset that's extremely light and durable. With a direct mount chainring saving even more weight, there's almost no more efficient way to turn your rear wheel without a motor. X-SYNC(TM) 2 Eagle Chainring Aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. DUB(TM) Technology Compatible with all existing BB sizes and frames. BOOST BOOST specification opens up the opportunity for improved frame geometry with shorter chainstays, wider and stiffer suspension pivots, a wider range of chainring options, and bigger, wider tires. Carbon Tuned Crank Arms This proprietary SRAM carbon layup design removes weight where it's not required for strength. The result is an extremely lightweight and durable crankset. | SRAM X01 Eagle Crankset 2022 - 170mm,32t Size 170Mm32T
