Size Guide & Compatibility
Size Guide & Compatibility
Choosing the right size is important for comfort, handling and riding efficiency. If you are not sure which size to choose, please send us your height, inseam, riding style and current bike size. We can help recommend a suitable frame size.
Please also confirm component compatibility before ordering, including groupset type, bottom bracket standard, crankset, wheelset, thru-axle size, brake rotor size, tire clearance and electronic/mechanical shifting setup.
If you are planning a custom build, contact us before purchase so we can help reduce compatibility mistakes.
Custom Paint Notice
Custom Paint Notice
Most carbon frames are produced or finished after the order is confirmed. Standard production time is usually 15–25 days, depending on frame model, size, color and current production schedule.
Custom paint requires additional time. Chameleon paint, ice-crack finish, gradient colors, pearl colors and special logo designs may take longer because they require more painting and quality-check steps.
Custom paint may slightly increase frame weight compared with matte black or standard finishes. If your main goal is lightweight performance, we recommend choosing matte black.
For custom colors, please provide a Pantone color code or clear reference images. We will confirm the design details with you before production.

Took a while to arrive in post due to chinese new year.
But well worth the wait.
Great quality.
My fully fully built bike now only weighs 7kg
Très satisfait du cadre hormis la qualité de la quincaillerie. Dommage par la finition du cadre même à l'intérieur est très bonne.
Perfect frame! Great paintjob, build went smooth
