Shimano Crank Arm Protector Boots

Anything that helps minimize the impact of rock strikes is a plus. Appreciate that Thunder Mt stocks these and has them listed next the the crank arms that I bought…this takes real effort from the product page builders.

Only crank boots that work and last on Shimano cranks. Never ride without them!

These are the best crank boots, use them on all my Shimano cranks.
