Seka Spear RDC Frame

Road performance frameset with advanced aerodynamics.

The SEKA SPEAR RDC FRAME KIT is a high-end road bike frame designed for cyclists seeking lightweight, stiffness, and high performance on the road. Made with advanced carbon technologies and wind tunnel-optimized design, this frameset offers a combination of aerodynamics, vertical comfort, and precise control. The frame includes standard mounting points and features a construction that balances structural rigidity and responsiveness. It is compatible with a wide range of high-quality components and can be customized with various accessories and integrated components.

The geometry and construction have been optimized through CFD analysis and wind tunnel testing, with the goal of reducing aerodynamic drag and improving the frame's overall efficiency. The "Wind Eye" design on the seatstays helps reduce turbulence and increase vertical compliance, improving comfort over long distances and variable surfaces.
