SPEEDSTER RADICAL

INCOLOR SSR ABOVE AND BEYOND

FAST STRONG ELEGANT

SPEEDSTER RADICAL represents a further exploration of optimizing frontal area. We have incorporated a dual-steerer design into the lightweight frame and achieved weight reduction through an ISP seatpost structure.

A Narrower Frame
A Smaller Frontal Area

Shared load between inner and outer steerers ensures superior stiffness and fits standard integrated cockpits.

34mm

Outer Steerer

28.6 mm

Inner Steerer

586.59 cm²

Frontal Area

45km/h Proven in the Wind Tunnel. Built to Break Limits.

Compare to SR+

During 0-5° yaw angle, the Aero Drag of SSR was 5.35w lower than SR+ at maximum.

Compare to S5

During 0-20° yaw angle, average power saving of 3.99w compared to S5.

Integrated Seat Post, Surface Area As Low As 3325cm²

Lighter, yet Stiffer.

The inner and outer steerer tube construction delivers optimal aerodynamic performance. It is the ideal solution for creating a lighter frame with a superior stiffness-to-weight ratio.

By repositioning the primary T1100 fiber overlap to the sides rather than the top and bottom, we have enhanced lateral stiffness while simultaneously improving ride comfort.

We’ve utilized triple the amount of 80T pitch-based carbon fiber. This reinforces the frame’s foundational stiffness at the material level, effectively offsetting any stiffness loss caused by the narrowed structure.
