AERODYNAMIC STIFFNESS LIGHTWEIGHT AESTHETICS

SPEEDSTER

SPEEDSTER symbolizes our pursuit of speed and our exploration of design aesthetics

Thinner Top Tube for Enhanced Comfort

The top tube features a subtle taper and curvature, ensuring a friendly stand over height while delivering a sleeker, more aesthetic profile.

Integrated Cap with Less Performance Loss

Delivers a fully integrated look without compromising the performance of the carbon fiber.

Thinner Seat Tube

New UCI regulations now permit thinner seat posts.

Horizontal Edges

Head Tube only 40 mm width

Achieving the slimmest profile possible in a standard layout. This design exhausts every structural possibility to cut through the wind with minimal resistance.

More Refined Design

The seat tube is shifted rearward and utilizes the seat stay junction to fill the gap between the seat tube and the rear wheel as much as possible.(不确定）

Greater Aerodynamic Gains

At 42mm, the down tube is slimmer than most aero bikes. When paired with INCOLOR aero bottles, it delivers superior aerodynamic efficiency.

Enhanced Aesthetics

No-hole design for a cleaner aesthetic

626.64 cm²

Minimized Frontal Area

Narrowed Head Tube Design

With a narrowest point of just 40mm, this design directly reducese the frontal area at the front end.

Slimmed Downed Tube

Reduces the frontal area at the frame's midsection to minimize impact drag from airflow.

Aerodynamic Bottom Bracket

Shaped to follow airflow trajectories, this design prevents turbulence and extra drag while reducing the frontal area.

Thinner Seat Tube & Seatpost Design

Reduces the longitudinal frontal area at the rear of the frame to minimize airflow drag.

Fork & Integrated Cockpit Aero Design

Dual optimization at the front (slim profile + aero shaping) to significantly reduce aerodynamic drag.

High-Precision Algorithms

Delivering superior numerical precision and flow field fidelity, validated by wind tunnel data.

Unique Offseted Steer Tube Design

The unique offseted design of the steer tube, combined with the cable guide inside the head tube, allows the head tube could be narrowed to only 40mm. While the steer tube diameter remains at 28.6mm.
Compared to special-shaped steer tubes, it provides better stiffness, strength and compatibility.

UNIQUE GEOMETRY

With a 72-78mm bottom bracket drop, smaller head tube angle, 405mm short chainstays, and 58mm fork trail, all of these make INCOLOR SPEEDSTER have excellent cruise stability.This geometry minimizes body roll and enhances steering tracking during seated pedaling, ensuring superior stability on both climbs and descents. Meanwhile, the short chainstays and trail tuning preserve an agile, responsive feel when out of the saddle.
