What front derailleur mount does a Orbea Oiz XC use?
The front derailleur fitment standard on a Orbea Oiz XC, and how to pick the right part.
| Frame | Orbea Oiz XC |
|---|---|
| Front derailleur mount | Braze-on (direct-mount) front derailleur (braze-on tab) |
| Mount / band size | no clamp, bolts to a frame tab |
| Typical class | carbon and higher-end aluminium road, gravel and MTB frames with a moulded or welded derailleur tab |
The Orbea Oiz XC uses a ZS44 zero-stack upper headset (zero stack, 44 mm), a 30.9 mm class seatpost, a 15x110 mm Boost front thru-axle at the front (15 mm x 110 mm Boost, front) and a braze-on front derailleur.
Most builds are 1x, so the front-derailleur mount note applies only to 2x setups. The rear is typically Boost 12x148; confirm your generation. The bottom bracket is covered on its own page.
