Incolor SR Frameset
Meet the Incolor SR Frameset, 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.
Incolor SR Frameset — Features & Benefits
- Aero, Verified: LES CFD + wind-tunnel data; ~3 W less drag at 45 km/h (≈21 s/100 km gain).
- Ultra-Small Frontal Area: ≈626.64 cm²—smaller than leading aero frames.
- Pedal Stiffness: up to 175 N/mm in SR layup for punchy acceleration.
- Offset Steerer & Narrow Head Tube: 28.6 mm steerer with ~40 mm head tube width for stiffness/compatibility.
- Handling DNA: Short 405 mm stays and size-scaled trail for stability at speed and agile sprints.
- Real-World Versatility: Fits up to 38C slick (≈46 mm inner width at fork/frame).
- Quiet, Serviceable Routing: Transportation-friendly cable guide; flexible spacer set for easy installs.
