INCOLOR SR / SR+ — “Speedster” — the pursuit of the quintessential road bike: aerodynamic, stiff, light and unmistakably elegant. Designed through advanced CFD and wind-tunnel testing, with an offset steer-tube, progressive geometry and full cockpit-to-seatpost integration, the Speedster turns every watt into forward motion.
SR or SR+ — two builds, one platform
- SR — M60 + T800 carbon · ~758 g frame · 175 N/mm bottom-bracket stiffness. The Speedster at its sharpest value.
- SR+ — T1100 + 80T pitch-based carbon · 720 g frame · 181 N/mm stiffness · titanium 3D-printed accessory pack (−45 g). The lightest, stiffest expression of the Speedster.
- Geometry and aerodynamics are identical across both — choose your weight, stiffness and budget.

SSR = the aero halo frame. SR+ = the lightest, stiffest all-rounder. SR = the same shape and aero for less. VOYAGER = drop-bar gravel for everything off the smooth stuff.
Engineering
- Ultra-low frontal area: 626.64 cm² — 3.2% smaller than the Cervélo S5 and 1.7% smaller than the Tarmac SL8.
- Proven aero — LES-CFD plus Silverstone Sports Engineering Hub (UK) testing: ~3 W less drag at 45 km/h vs the Tarmac SL8, roughly 21 seconds saved over 100 km.
- Offset steerer — a 40 mm head tube on a standard 28.6 mm steerer: narrower frontal area with no loss of stiffness or cockpit compatibility.
- Asymmetric T47A bottom bracket — +10% stiffer than T47-68, fully power-meter compatible.
- Future-proof — up to 38c tyres and a UDH derailleur hanger.
What’s included
- INCOLOR SR/SR+ frame & fork · aero integrated cockpit · Speedster aero seatpost · accessory package (thru-axles, headset). SR+ adds the titanium 3D-printed pack (−45 g).
