Paul Component Engineering Chain Keeper is a simple, overbuilt solution for keeping your chain on the ring when the trail gets rough or the road gets rowdy. Machined in the USA fro m aluminum, it mounts to the seat tube and holds your chain in place without the bulk of a full bash guard setup. Paul Component Engineering has been making hardware like this for decades — tight tolerances, clean aesthetics, zero compromise on material quality. The Chain Keeper is designed for single-chainring drivetrains where chain retention matters and extra weight doesn't. Whether you're running a 1x setup on a gravel bike or keeping a dedicated single-speed tidy, this is the kind of component that installs once and stops being something you think about.
