Winspace has officially launched the SLC5, its latest high-performance road bike frame, claiming the title of “All-Terrain Master” at Eurobike 2025. They introduced it alongside the new HYPER 5 wheelset, G3 gravel bike, and T1600 aero frame. The SLC5 targets riders seeking a lightweight, yet aerodynamic frame.
At just 705 grams for an unpainted size Medium, the SLC5 is one of the lightest production frames Winspace has ever made, just slightly heavier than the SLC3 climbing frame. Considering the tubing, it’s a much lower weight than I would expect.
It is designed to compete with (and benchmarked in a wind tunnel directly against) the Specialized S-Works SL8; the SLC5 should bring elite-level performance to a broader audience. The wind tunnel data have not been published yet, though.
The frame features a BSA-68 bottom bracket, offers 32mm tire clearance, and comes in five sizes. That tire clearance is today’s standard for road bikes. The frame is made of premium materials, including T1000, T1100, M65, and M46.
A fully built SLC5 with HYPER Light wheels and Shimano Ultegra Di2, weighted around 7.5 kg without bottle cages and pedals.
Positioned as the all-around sibling to the more aggressive T1600 aero frame, but more aggressive and performance-oriented Agile, the SLC5 rounds out Winspace’s lineup of road frames.
Design-wise, it’s similar to the SL8 mentioned above, especially in the rear end, which seems similar. The head tube has a relatively sharp leading edge, similar to the T1600. This is a feature Winspace wants to implement on their future frames to unify the lineup. Of course, it also has sealed through axles, like the other Winspace frames.
Pricing and availability will be announced soon, but Winspace told me that this one will be a more premium frame, so I expect a price tag above $2000. I will update this article once I learn more details.

By the way, Winspace skipped the SLC4 naming because number 4 is considered unlucky in Chinese culture.
