Designed specifically for Eagle chains and drivetrain systems, it delivers a seamless, responsive ride with optimal gear engagement.

Technology & Compatibility:

The SRAM DUB spindle interface provides a lighter, stiffer, and more reliable crank connection, compatible with DUB bottom brackets (sold separately). The Boost-compatible design (141/148 spacing) ensures perfect alignment with modern 29-inch and 27.5-inch wheel setups, optimizing wheel placement for better clearance and improved handling. The crankset's 170mm crank arm length is ideal for mountain biking, offering a balanced combination of control and power.

Style & Use Case:

With its sleek black finish, the SRAM XX1 Eagle Carbon Boost Crankset combines high-performance engineering with a clean, minimalist aesthetic. Perfect for trail, enduro, and all-mountain riders, this crankset is designed to withstand the rigors of aggressive riding styles while delivering precise power transfer and reliable performance across varied terrains.
