Derailleurs are of no use with one
Accidents are unavoidable on the trail, and as a result, an all-too-common symptom is a bent or broken derailleur hanger. Sadly, even the almighty Yeti SB-66 Carbon is prone to the occasional disruption of service. So, regardless whether you're preparing for your own future crashes, or you're simply replacing the hanger that you've already broke, the SB-66 Carbon Rear Derailleur Hanger is what you've been looking for. Remove, replace, and get riding again.
The SB-66 Carbon Rear Derailleur Hanger is available in One Size and is intended for use with the Yeti SB-66 Carbon frame.
