About this product

A Chain Keeper (dummy hub) compatible with both QR and 12 mm thru-axle dropouts without switching of parts or adapters.

Featuring a free-spinning and side-shifting pulley wheel, allowing shifting of the derailleur and a high polymer spacer providing abrasion protection against dropout surfaces, this is a quick and easy tool to have on hand for routine cleaning and maintenance work.

Pulley wheel is compatible with single -13 speed chains.

If the handle comes loose, clamp on to the tool with a 14 mm wrench, then tighten the handle.

All tools should be stored in a dry environment.
