Chain Guide for Thru-Axle FEEDBACK SPORTS Thru-Axle Chain Keeper

The Feedback Sports Thru-Axle Chain Keeper Chain Guide is an extremely practical maintenance and protection tool for all modern bikes equipped with disc brakes and thru-axles (Thru-Axle). It fits in place of your rear hub when the wheel is removed.

Its role is twofold: it maintains constant tension on the chain to prevent it from derailing or rubbing against the rear stays of the frame, and it allows you to spin the crank arms freely. It is the ideal accessory for thoroughly cleaning and lubricating your drivetrain without getting your rear wheel dirty, or for securing the chain when transporting your bike in a car boot or travel bag.

Does this tool come with its own axle? No, this clever model uses your bike's original 12 mm thru-axle directly. Simply remove your rear wheel, slide the Chain Keeper onto your axle, then reinsert the axle into the frame and tighten it as normal.

Can you shift gears on the derailleur when the tool is installed? The plastic roller keeps the chain on a fixed straight line (generally aligned with the middle of the cassette space). You can slightly actuate the rear derailleur to adjust the ideal alignment, but the tool is designed to hold the chain in a stable position for washing or transport, not to simulate shifting through all gears.

How to clean the roller after a heavy chain degreasing? The high-quality composite plastic does not absorb impurities. After rinsing your chain, simply wipe the roller with a clean cloth to remove excess dirt or degreaser. It requires no specific maintenance.
