SRAM XX1 Eagle DUB Crank Arms
The SRAM XX1 Eagle DUB Crank Arms are the lightest, stiffest and strongest SRAM MTB carbon crank arms to date! These feature SRAM’s 8-bolt DUB mounting interface and require the use of a SRAM DUB bottom bracket. Designed to be run with 8-bolt power meters and chainrings, this crankset provides reduced drivetrain noise and improved mud and debris clearing.
Key Product Details
Compatibility:
This crankset uses SRAM’s 8-bolt chainring interface and is compatible with DUB bottom brackets. See Compatibility tab for more information.
Key Features:
Carbon fiber construction, designed to match XX1 Eagle AXS components, available for Boost and Super Boost MTB frames. See Specs tab for more information.
Advice From Our Staff:
This crankset is made 8-bolt power meters and chainrings and is designed for riders who are looking for maximum weight savings and performance gains.
Options
Crank arms: 165 mm | 170 mm | 175 mm
Chainline: Boost 52 mm | Super Boost 55 mm
Other Versions to Consider
SRAM XX1 Eagle DUB SL Crankset: SRAM also manufactures the SRAM XX1 Eagle DUB SL Crankset which uses SRAM’s 3-bolt interface.
Compatibility
These crank arms use SRAM's 8-Bolt interface, meaning compatible power meters or chainrings must also use an 8-Bolt interface.
If you are looking for the 3-bolt version which can be used with a standard chainring (non-power meter), please see: SRAM XX1 Eagle DUB SL Crankset.
