Good to know: Configurable build
Configurable build (at least partly: the cockpit or bar width, for example). The stock build below is only one of the options.
Geometry ?
Berk Cesta 2026 geometry in sizes S–L: stack 542–579 mm, reach 378–405 mm, head angle 73–74°.

| Reach | 378 mm | 390 mm | 405 mm |
| Head angle | 74° | 73° | 73° |
| Seat angle | 74° | 74° | 74° |
| Seat tube (?) | 520 mm | 535 mm | 550 mm |
| Head tube | 130 mm | 140 mm | 160 mm |

(?) by the seat tube length: the manufacturer doesn’t say whether it’s measured centre to centre (c-c) or centre to top (c-t).

Spotted a mistake or a missing build? Let me know.
Are you the manufacturer, or do you sell this bike? I’m missing 5 values for this model’s stem and bars. Add them
