The Thru Axle Chain Keeper is a must have investment for cycling enthusiasts. 3D printed using a high-quality PETG (Polyethylene terephthalate glycol) material. This is an ideal cycling accessory to keep your bike chain secured during washing, tune-ups, and traveling. It fits perfectly on a 12mm thru-axle dropout system and no tools are required to use it. By keeping the chain tension at the right amount, you won’t have to worry about rear derailleur drop out from loosening during travel / washing. Even worse, you will not have any accidental damages/scratches to the frame caused by loose chain.
