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 and all other square taper cranksets & bottom brackets using 8mm (M8x1mm) fixing bolts.

Pro tip: put a drop of blue thread locker on the threads before installing to keep them from backing out on you and needing constant adjustment.
