What seatpost diameter does a Canyon Inflite cyclocross use?
The seatpost fitment standard on a Canyon Inflite cyclocross, and how to pick the right part.
| Frame | Canyon Inflite cyclocross |
|---|---|
| Seatpost diameter | 27.2 mm |
| Diameter | 27.2 mm |
| Typical class | the de facto standard on modern road and gravel frames, and many hardtail and lightweight full-suspension frames |
The Canyon Inflite cyclocross 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.
