Why Keep the GXP Self-Extracting Crank Bolt on Hand?

The SRAM GXP self-extracting crank arm bolt is OEM-spec hardware for any GXP crankset, built with an integrated extraction mechanism that lets you pull the crank without a separate crank puller. Thread it in, apply torque, and the arm pops free cleanly without additional tooling or risk of damaging the spindle interface. Available in both M15 and M22 threading to cover the full range of GXP-compatible cranks across SRAM and Truvativ product lines. Alloy construction keeps the part light while meeting the torque spec requirements the GXP interface demands.

This is the part that makes crank removal a straightforward task rather than a toolbox scramble, and replacing a worn or stripped bolt before it becomes a problem is cheap insurance for any drivetrain running on GXP spindle architecture. Proper bolt engagement drives correct crank retention and bearing preload, so running a compromised unit is a risk not worth taking. One rounded or cross-threaded bolt and the crankset is stranded mid-ride or stuck on the workstand. A smart, simple spare for any home mechanic o
