PEDRO'S Pro Chain Keeper — 12mm thru axle, yellow

The Pro Chain Keeper replaces the rear wheel to maintain chain tension and protect the frame when the wheel is removed for cleaning, storage, or transport.

• Takes the place of the rear wheel to provide tension on the chain and protect the frame during maintenance or transport.
• Quick, one-handed installation on standard QR-style dropouts; removable pulley wheel designed to work with 12mm thru axles.
• Stainless-steel and aluminum construction with a heavy-duty, solvent-resistant plastic pulley for long life.
• Compact and lightweight for easy storage and transport while keeping the chain secure.

Use it for safe, simple maintenance and to prevent frame damage when the rear wheel is off.
