SRAM GX Eagle Carbon DUB Boost 曲柄组 1x12

Day in, day out, this is the Eagle ecosystem at its best. GX Eagle combines the full-featured capability of Eagle technologies, in a group that realizes the potential within every build.

This is where you’ll find the best aluminum MTB crankset SRAM make. GX Eagle has its own version of their new, 520-percent range, 10-52t cassette, for more top end speed or a more comfortable climb - should you choose to run it. If not, GX Eagle is backwards compatible, making replacement parts at the ready. Like other Eagle groups, it gets its own group master colorway as part of SRAM`s new Eagle Colorsystem, allowing for full group or fully curated builds. It’s the simplest, most trouble-free drivetrain system ever made, offering the freedom to mix and match with any component within the expanded Eagle ecosystem.

The SRAM carbon GX Eagle crankset delivers consistent performance every time out. Featuring SRAM's X-SYNC 2 tooth profile chainring, the Carbon GX crankset is engineered for complete chain control. Each tooth's thickness is precisely toleranced and controlled to work seamlessly with the chain's inner and outer links. DUB technology features a better-engineered bottom bracket and a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of durability.

BOOST™
BOOST is the standard wheel and drivetrain specification that opens the opportunity for improved frame geometry with shorter chain stays, wider and stiffer suspension pivots, wider range of chainring options, as well as more clearance for bigger tires and wider, stiffer wheels.

Eagle™
Eagle technology represents our newest 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 500%, which is equal to 2x11 drivetrains.

X-SYNC™ 2
SRAM X-SYNC 2 Eagle is the next evolution of SRAM X-SYNC technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC 2 Eagle design reduces friction and the accumulation of mud, grit and grime.

DUB Technology
The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler - better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.
