Introduction

Chain tension is important for the proper operation of your bike.

If the chain is too loose, then the derailleur may not function optimally, and the chain isn't as coupled with the bike's gears.

This guide shows you how to tighten your chain by simply nudging the rear wheel farther back in its housing, placing more tension on the chain so that it is no longer loose.

Shift the rear derailleur into its outermost gear, and the front derailleur into its outer gear.
