SEKA : Exceed RDC : Bike Frameset – White XS

EXCEED RDC is a fully integrated aerodynamic frame, fork and handlebar combination which has been designed to slice through the air with the minimum effort from the rider. Lighter and more stiffer than normal EXCEED series.

High performance composite processes to ensure stiff, light and compliant frame

One piece handlebar included to ensure the lowest system drag

Fully integrated cable routings for both mechanical and electronic shifting

2 eye catching finishes available

Weight – 775g (Medium unpainted)

Feature Technology

HPC – HIGH PERFORMANCE COMPOSITE

The HPC process starts with a high-quality carbon fibre material. Our engineer started from scratch to fundamentally redesign a bike frame that challenge the norm to exceed the expectation of today rider.Using Finite Element Analysis to optimize lamination, geometry and cross-sectional contour of our bikes to delivering a perfect balance between stiffness, lightweight and compliance.

HPC is applied to the whole process of design, simulation analysis, production, testing until the final product hits the road.

ATS – ASYMMETRIC TRANSMISSION STRUCTURE

The frame has several areas which are asymmetric – bottom bracket, fork, chain stay and bottom of the seat tube. By using different tube types, material lay ups in the higher stress areas the SEKA team have managed to balance the forces between left and right side of the frame and fork. This improves the overall transmission efficiency and helps build a more stable and balanced structure.

AERODYNAMICS

Using airflow dataset and know-how from National Advisory Committee for Aeronautics (NACA).Our frame designer develops our Exceed series frame to provide gain in aerodynamic to provide unfair advantage gain. Using latest computational fluid dynamics ( CFD ) analysis to develop our most Aero frame.

FRAME STRENGTH

By optimising the material usage and layups the weight can be kept low but still ensuring it exceeds the stringent requirements of the ISO standards. For example one of the ISO4210-6 tests requires 100,000 cycles of 120N at 120 times per minute and this exceeded by 20%. The optimisation results in a head tube stiffness of 143N/mm and a bottom bracket stiffness of 215N/mm which results in more power from each pedal stroke going to the road.
