Orbea Terra, Avant OMP and Orca OMR Through Axle Rear Derailleur Hanger
This derailleur hanger is compatible with the following bikes:
Orbea Terra 2017/2018 carbon (SRAM e-Tap and hydraulic disc, Di2 and hydraulic disc, SRAM Mechanical group and hydraulic disc, SRAM e-tap and hydraulic disc)
Orbea Avant OMP 2017/2018 carbon (both mechanical and hydraulic disc brake)
Orbea Orca OMR 2017/2018 (both Di2 and mechanical hydraulic disc versions)
This is always a useful part to have a spare as they tend to be bike specific, the derailleur attaches to this and the hanger will break before the derailleur or frame :)
Orbea call this part a Pata de cambio 142x12mm-17
Colour: Black
If you are not sure if this is the right derailleur hanger for your bike - go to the Orbea spare parts section of their website and enter your bikes serial number.
