The goal here is not saving grams on the climbs but holding high speed for kilometre after kilometre in an aero position.\u003c\/p\u003e\n\u003cp\u003eIt is supplied on its own, with no hub or spokes, to build a custom TT front wheel or rebuild an existing one. It is not an SL version: the 77|88 series focuses on very deep profiles and a construction geared towards stability and speed rather than minimum weight.\u003c\/p\u003e\n\u003ch2\u003eA 77 mm profile: speed and control in the wind\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThe Turbulent Aero programme grew out of two years of wind measurements on American roads, later replicated in the wind tunnel: the shape is optimised for real gusts and real angles of attack.\u003c\/li\u003e\n\u003cli\u003eIn the 77|88 pairing the front stays shallower than the rear: 77 mm delivers a big drag reduction while keeping the steering manageable in a crosswind.\u003c\/li\u003e\n\u003cli\u003eThe wide profile, 31 mm externally, suits modern tyres and works well with the recommended widths.\u003c\/li\u003e\n\u003cli\u003eCompared with 57 or 64 mm front rims, it gains speed on long, steady-paced legs where only watts and position
