Scicon Chain Keeper
Scicon Chain Keeper protects your bike frame from damage when your rear wheel is removed. Whether you're packing your bicycle for travel, doing maintenance work or hanging your frame for storage, Scicon Chain Keeper holds your chain in place and prevents frame damage. Simply mount it onto the drive-side's rear dropout. Your chain rests on the keeper rather than left dangling and ready to damage or scratch your bike. Compatible with all road and triathlon frames.
