What seatpost diameter does a Cube Agree C:62 use?
The seatpost fitment standard on a Cube Agree C:62, and how to pick the right part.
| Frame | Cube Agree C:62 |
|---|---|
| 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 Cube Agree C:62 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.
The 27.2 mm figure is the mainstream disc-road interface; many of these frames ship a proprietary aero-shaped post, so confirm the exact part. The bottom bracket is covered on its own page.
