Rook/Colt Derailleur Hanger

Replacement derailleur hanger for Surface 604 Rook, Colt, and V Rook eBikes. The derailleur hanger is a sacrificial component designed to bend or break in a crash to protect the more expensive frame and derailleur.

If your shifting has suddenly gone haywire after an impact or tip-over, a bent hanger is almost always the cause. An inexpensive part that every rider should carry as a spare.
