Блок передних звезд SRAM GX Eagle DUB 1x12-speed 55mm chainline 32T

DUB technology delivers the lightest, stiffest and strongest crankset available.

SRAM CARBON TUNED crank technology provides extreme stiffness and light weight.

The X-SYNC 2 chainring provides significantly quieter performance, with better mud clearing and extraordinary durability.

colorway is matched to work with XX1 Eagle AXS enabled componentry.

TECHNOLOGIES

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 est 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features 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 520%, 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 - The relationship between bottom bracket spindle and bearing is the core of DUB technology. It's where stiffness meets durability. We 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.

CARBON TUNED - Strength and stiffness where you need it. Lightweight like you want it. Proprietary SRAM carbon lay-up design increases thickess and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.
