A precision-machined replacement for the derailleur hanger on Cervelo R.A.T.-equipped bikes, matching the stock hanger's geometry and construction for crisp shifting. Combine it with a Robert Axle Project Lightning axle for a complete threaded thru-axle system, or fit it alone to replace a bent or worn R.A.T. hanger.

Compatibility & fit

Fits Cervelo R.A.T.-equipped bikes; a direct replica of Cervelo's own DRH-WMN112 hanger. Installs with a standard 6mm hex key. The Tune workshop can fit a new hanger and check derailleur alignment.
