Good to know: Integrated cockpit · Future Shock

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.

Future Shock (travel 20 mm) is already part of the published stack, so I sit the stem directly on it, with no more than 30 mm of cover and spacers underneath. This is an estimate: once the unit sags under your weight, the bars end up a few millimetres lower.
