Slotted steel Rainbow Chain idler arm 8mm tk. x 20mm x 34mm

This Rainbow arm can hold an idler pulley with or without the included spring-loaded swing arm. Subject to your design preference.

To operate properly the Rainbow arm must be mounted on 2 chain stays in a straight-line vertical position in order to line up with the drive chain. Your bike frame may or may not be compatible with this idler bracket.

Check out the fit requirements first before ordering as cost to return is expensive and not worthwhile.
