Incolor SR Frameset
Meet the SR, a fast, quiet aero frameset that’s easy to live with. By slimming the head tube, seat tube and fork blades, plus shaping the BB area and cockpit, the SR achieves an ultra-small frontal area (smaller than flagship aero frames like S5 and SL8). In wind-tunnel testing at 45 km/h it cuts about 3 W of drag—roughly 0.12 km/h faster or 21 s saved per 100 km.
The smart offset steerer and internal cable guide let the head tube narrow to 40 mm while keeping a standard 28.6 mm steerer, so you get crisp steering, strength and broad compatibility without weird standards. A lower BB, calmer head-tube angle and short chainstays give the SR confident straight-line stability with that lively, sprint-ready snap.
Practical touches seal the deal: a T47A threaded bottom bracket for easy service and extra stiffness (about +10% vs T47-68), a UDH hanger for precise shifting and durability, and clearance for 38C slicks (≈46 mm internal width) so you can ride fast on smooth tarmac, rough roads, or both.

Build Notes
- Use a T47A BB matched to your crank spindle (24 mm / 30 mm / DUB).
- Confirm bar/stem compatibility if using third-party integrated cockpits.
- For mixed surfaces, start with 30–34 mm tires and tune pressure to terrain.
