Fit A Shimano Hollowtech Crankset On A Bike

Step of 3: Replace A Shimano Hollowtech Crankset On A Bike

Introduction

Modern bikes usually have cranks made of aluminium, they are mounted on an axle made of harder material, usually steel. If there's any play between the cranks and the crank axle the soft aluminium will soon get worn to the point where it's impossible to lock the cranks. If the cranks are loose don't ride the bike.
