The headset fitment standard on a Bianchi Sprint, and how to pick the right part.
| Frame | Bianchi Sprint |
|---|---|

The Bianchi Sprint 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.
