SRAM X01 Eagle Boost 148 DUB 12-sp. 170mm Cr-set 170mm in Lunar Polar

Brand:Sram

Code:CW8603000LUNARPOLAR

Strength is how the X01 Eagle DUB crankset takes capability to places never before reached. It is the strongest crank in the entire Eagle ecosystem.

Featuring industry-proven DUB technology to radically simplify the relationship of spindle to bottom bracket, this crankset delivers unprecedented simplicity, compatibility and durability. The X01 Eagle DUB Crankset comes with the Eagle Colorsystem, in the X01 signature colourway to complement other cassette and chain colours. With a raw aluminium finish on the X-SYNC 2 chainring teeth, it maintains a fresh appearance throughout its long lifespan.

Eagle technology represents a 1x drivetrain solution that is lighter, simpler, and more durable, providing an expanded gear range of 520%. The X-SYNC 2 design provides better chain retention for a smoother, more efficient pedal feel while reducing friction and the accumulation of mud, grit and grime. DUB technology better integrates the relationship between the chainring, crank, spindle and bottom bracket for improved performance. Proprietary CARBON TUNED carbon lay-up design increases thickness and stiffness at critical stress areas, while BOOST technology allows for improved frame geometry with shorter chain stays and wider suspension pivots.

Features:

  • Strongest crank in the entire Eagle ecosystem.
  • Signature X01 colourway as part of the Eagle Colorsystem.
  • Raw aluminium chainring teeth for a long lifespan.
  • Precision CNC machined direct mount ring.
  • DUB technology for simplified spindle to bottom bracket integration.
  • CARBON TUNED architecture for weight savings and strength.
  • BOOST specification for improved frame geometry and clearance.
