Paul Component Engineering Chain Keeper

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 from 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.
