What front derailleur mount does a Trek Emonda SLR (2024 on) use?
The front derailleur fitment standard on a Trek Emonda SLR (2024 on), and how to pick the right part.
| Frame | Trek Emonda SLR (2024 on) |
|---|---|
| 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 Trek Emonda SLR runs an integrated IS42 upper headset with a 28.6 mm steerer, a 27.2 mm class road seatpost interface, a 12x100 front thru-axle and a braze-on front-derailleur mount.
The 27.2 mm figure is the mainstream disc-road interface; Trek's own aero posts are proprietary in shape, so confirm the exact Trek post part. The bottom bracket on this frame is a threaded T47 shell, covered on its own page.
