The SRAM XX1 Eagle DUB Crankset is one of the most lightweight cranksets on the market for cross-country focused mountain bikes. It features DUB technology which provides better sealing at the bottom bracket and creates the strongest, stiffest, and lightest crankset available. This version also has a Boost-specific design to support 12 x 148mm rear axles. The crank is made with a reengineered carbon layup which is lightweight and incredibly stiff. This layup is tough enough to handle aggressive terrain including rocks and roots without sacrificing any weight. A new X-Sync 2 chainring technology was designed for Eagle chains and drivetrain, providing quiet performance with great mud clearing and durability. This crankset is an excellent choice for riders with a lightweight build who want to hit the highest speeds on the trails.
