Removing the rear wheel for cleaning or travel leaves your chain dangling against the chainstay where it scrapes paint and shifts unpredictably when you rotate the cranks to work on the drivetrain. The Feedback Sports Chain Keeper mounts into the rear dropouts to maintain chain tension and protect the derailleur when the wheel comes off. The Delrin roller spins freely as you backpedal through gears during chain cleaning, without the grinding metal-on-metal contact that happens when the chain drops onto the frame.

Feedback Sports machines the body from aluminum with tool-free clamping that adjusts to your frame by hand. For quick-release dropouts, the threaded clamp closes down on 9mm spacing with finger pressure. For 12mm thru-axle frames, swap to the included adapter that passes through both dropout tabs and secures without threading. The single-hand operation means you're not fumbling with wing nuts or separate tools when you're trying to get the bike washed before a ride.

The Delrin roller positions where the lower chain run would normally contact the cassette, keeping tension on the rear derailleur cage. This stops the chain from swinging into the chainstay during transport and allows you to shift through the full cassette range when you're degreasing and re-lubing the chain. Works with road, cyclocross, mountain, and e-bike drivetrains using standard dropout spacing.... Read More
