De Rosa 838 (2026)

endurance road · carbon · sizes 46–56 · tyres up to 32 mm Manufacturer’s website

The manufacturer doesn’t publish stack and reach, so I can’t work out where the bars would be.

Good to know: Integrated cockpit · Configurable build

Integrated cockpit (a one-piece bar and stem) on at least one build. Changing the length means replacing the whole cockpit, and not every length exists. Check which length the bike actually ships with before you buy.

Configurable build (at least partly: the cockpit or bar width, for example). The stock build below is only one of the options.

Are you the manufacturer, or do you sell this bike? I’m missing 6 values for this model’s stem and bars. Add them
