To serve riders progressing to the next level, Chermin R strikes a refined balance in the "impossible triangle" of stiffness, aerodynamics, and weight.
It reflects our deep understanding of what a true progression in advancing bike design should be.

Parabolic distribution in geometry based on size 54 ensures consistent ride feel across 7 frame sizes, fitting riders from 156–195 cm.

(Parabolic Geometry: Human limb proportions don’t increase or decrease proportionally with height. To maintain consistent riding posture, STR is progressively increased in both larger and smaller frame sizes)

Chermin-R delivers WorldTour-level performance to advancing riders, with strategically engineered tube profiles tailored for every section of the frame.

Aerodynamics

Head tube, down tube, and seat tube are shaped to minimize drag.

Stiffness

Bottom bracket area and chainstays are reinforced to maximize power transfer.

Vertical Compliance

The lower seat tube near the bottom bracket and the seatstays are tuned for road-smoothing comfort.

Developed in partnership with the HKUST Aerodynamics Lab, our CFD simulations and wind tunnel testing incorporated real rider dynamics.

Why we choose HKUST

HKUST features a high-precision closed-loop wind tunnel (turbulence <0.12%) and a rotating-wheel test rig that simulates real-world riding conditions.

The entire frame is built using a monocoque mould, with no bonded joints. This enhances stiffness, reduces weight, and delivers superior climbing and acceleration performance.
