Born to race, the generation 2 T1550 takes everything to the next level. It retains the aggressive geometry and performance focus, but with further optimisation. Italian design meets our expertise in carbon fibre, creating a perfect blend. The T1550 2nd Gen. is a bike builder's dream. Fully UCI certified, it's ready to compete at the highest levels.

T1000+T800 Carbon Fiber One-Piece Molding Process
The Winspace T1550 2nd Gen. frameset features a T1000 + T800 carbon fiber One-Piece molding process, which ensures higher-quality stability and lightweight construction. This process also results in a seamless frame, allowing for more direct force transmission and a sturdier frame structure.
Aggressive Yet Optimized Geometry
Building on the extremely aggressive design of the previous generation, we've optimized the T1550 to be more ergonomic without sacrificing performance. This refinement makes it less aggressive and more user-friendly, striking the perfect balance between performance and comfort.
ACR Headset
The Winspace T1550 frameset comes with an ACR headset that features a fully hidden internal cable routing design. This design not only enhances the bike's appearance but also protects the cables from damage, ensuring that they function properly for years to come. Additionally, the internal cable routing design reduces air resistance, further enhancing the bike's aerodynamic performance.
Flexible Handling Performance
The Winspace T1550 frameset has been designed to provide flexible handling performance, allowing you to maintain optimal control over the bike at all times. The frame's geometry and fork design work together to provide excellent handling, making it easy to navigate even the most challenging terrain.
