How to Put a Mountain Bike Chain Back On: A Comprehensive Guide
To put a mountain bike chain back on, first, shift the chain to the smallest chainring in the front and the largest cog in the rear. Then, lift the rear tire off the ground and use your hands to guide the chain onto the chainring and cassette. If needed, use a chain tool or pliers to hold the chain while guiding it. Finally, double-check the chain’s position and use your hands to spin the pedals and make sure the chain runs smoothly.
