Sugino CPB 8mm hex crank arm bolts
Super nice 8mm cro-mo crank arm fixing bolts with machined aluminum dust shields and o-ring seals to keep water out of places you don't want water to be.
Compatible with Sugino 75, Sugino RD2, Sugino RD4 and all other square taper cranksets & bottom brackets using 8mm (M8x1mm) fixing bolts.
ⓘ Put a drop of medium-strength (blue) thread locker on the threads before installing to keep them from backing out and needing constant adjustment.
Specifications
• chrome plated steel bolts with aluminum dust shields
• sold in pairs
• colors: black, gold, red, blue, silver
Recommended torque
Proper tightening is crucial to prevent the crank from loosening and damaging the crank arm.
The recommended torque spec for square taper crank bolts is generally 35-45 Nm (300–400 in-lbs) for most setups.
Tighten bolts in stages to 35-50 Nm, alternating sides, or until securely seated. Do not over-torque, as this can deform the crank/spindle interface.
Be sure to check the bolt tightness after the first few rides, as the arms will typically settle on the spindle and the bolts will require slight re-tightening.
