What front derailleur mount does a ENVE MOG gravel use?
The front derailleur fitment standard on a ENVE MOG gravel, and how to pick the right part.
| Frame | ENVE MOG gravel |
|---|---|
| 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 ENVE MOG gravel uses a IS42 integrated upper headset (integrated, 42 mm), a 27.2 mm class seatpost, a 12x100 mm front thru-axle at the front (12 mm x 100 mm, front) and a braze-on front derailleur.
Gravel builds are often 1x, so the front-derailleur mount can go unused. The 27.2 mm post is the class default; confirm the exact part before buying. The bottom bracket is covered on its own page.
