Chain Keeper is a terrible product for (modern) thru-hole axle bikes . The instructions for using this adapter are non existent. There are videos online but they dont provide any close ups of how the adapter attached to chain keeper or the axle itself. I think i finally figured it out but when using it it will poke the grommet ( plastic end cap cover - part of the bike) out on the other side. Not really that big of a deal but youll most likely need to buy new grommets to replace existing one as they wear out over time. Basically product is wirth it 100% for quick release but better to buy a $9.00 thru axle roller and use your existing thru axle to connect. One last thing. chain Keeper is advertised as being compatible out of the box with thru hole and quick release. My chain keeper did NOT come with the thru hole adapter and after many hours of trying to figure out how to get this to work properly with thru hole , relaized the adapter never came with my chain keeper.
