Good to know: Fit any cockpit you like · Configurable build
Fit any cockpit you like. Fairlight sells either the frame alone or a build you configure when ordering. The stem and bars are conventional (mostly FSA on the website) and the cables run externally, so you can fit whatever stem and bars you like. I’ve done about 20,000 km on my own Fairlight Strael 3.0, and the 4.0 is barely different.
Configurable build (at least partly: the cockpit or bar width, for example). The stock build below is only one of the options.
