Winspace has unveiled its new C6 bike at Rouleur Live in London. It bills the C6 as a performance endurance bike, saying it offers 40mm tyre clearance and endurance geometry, with vertical compliance at the rear of the frame.But while designed for longer rides and with a more upright ride position, Winspace says the C6 has racy handling with a performance-oriented steering geometry.Announcing the new bike, Winspace CEO Stephen Cai said: The C6 represents our belief that performance and endurance should work together. Weve taken our experience developing high-performance road bikes and applied it to a platform designed for riders who want responsiveness, efficiency, and the freedom to ride farther and faster. The C6 has 40mm tyre clearance, but Winspace says it still offers a performance-oriented ride. Winspace says it has engineered endurance comfort into the frame through its bowed seat tube and dropped seatstays, while a D-shaped seatpost is designed to increase the suppression of vibration from the road surface. There's in-frame storage in the down tube for your long-ride extras.Winspace also sells its Lun Hyper aero wheelsets and in September launched the G5 gravel bike, which retails at around half the price of competitors and offers 58mm front and 53mm rear tyre clearance. Winspace claims the rear of the C6 frame is engineered for comfort, while there's in-frame storage for ride essentials. We reviewed the Winspace M6 aero bike in September, commenting on its fantastic value for money and the broad range of customisation options available, which enable you to choose everything from the wheelset to cockpit dimensions and even crank length.Winspace is one of a number of Chinese bike brands making inroads into the Western market, while Chinese groupset brands are starting to nibble away at Shimano's dominance. At the end of October, the second-tier Team TotalEnergies announced it was swapping to Pardus bikes from Cube for 2027, along with a team-name change to XEFI as a new title sponsor takes over.Winspace says it will provide further details of the new C6 on 18 November, including specs, pricing and availability, so well update this post once we know more.
