The Feedback Sports Chain Keeper is an essential accessory for professional and DIY mechanics alike. When cleaning your bike, removing the rear wheel provides access to the backside of the chain and rear derailleur, and the inside of the seatstays and chainstays. Doing so removes tension in the chain, making cleaning difficult and awkward. A Chain Keeper installs on the rear driveside dropout to re-tension the chain without restricting access. Additionally, this device is helpful to keep the chain from getting tangled when storing or shipping a bike when the wheels must be removed. This modern, premium tool is manufactured from aluminum with a low-friction delrin roller, and is compatible with both quick release and thru axle dropouts. In typical Feedback style, the Chain Keeper is elegantly finished in anodized red with a laser-cut logo. Feedback Sports tools are covered by a 3-year warranty.
