How to Fix a Mountain Bike Chain: A Step-by-Step Guide
To fix a mountain bike chain, first, shift the chain onto the smallest chainring and smallest rear cog. Next, locate the broken or damaged link and remove it by bending the chain sideways so that the pin slides out. To fix the chain, use a chain tool to push the pin back in and reconnect the chain. If the chain is too damaged, it may need to be replaced.
