The Serpent 500522 41T aluminium idler gear is a straightforward metal alternative for the SRX2 MH that helps reduce wear and provides steadier rotation under race conditions.
The 41-tooth profile keeps meshing uniform to limit premature wear and maintain effective power transfer. Aluminium keeps the idler light while adding structural resilience versus softer materials.
This idler is appropriate for club and competitive drivers who want a tougher, more consistent idler component to support precise drivetrain behaviour.
