Morgan Blue Chain Keeper for Thru-Axles
The thru-axle version of the popular Morgan Blue chain keeper.
We advise to take out the rear wheel for better cleaning. Install the chain keeper to maintain the pressure on the rear derailleur. If you want to transport your bike in a box or in your car and you want to take out the rear wheel, we advise to install the chain keeper so that the rear derailleur stays in line.
