Used SRAM RED E1 crankset with 175 mm crank arms and DUB axle standard. Non-Wide road version, suitable for SRAM RED / Force / Rival AXS road drivetrains. Compatible with 1x12 or 2x12 setups depending on chainring configuration. Very nice condition with minimal signs of use. THERE IS A SLIGHT RATTLE IN THE INSIDE OF THE LEFT CRANK ARM, but it is not noticeable while riding.
