Lighter
Made from Toray T800 and M Series carbon,
top-tier materials offer enhanced load-bearing
capacity while reducing weight by 115g.
Steadier
Retains the high stiffness of the first generation, with optimised geometry and a longer RC and larger Trail for more stable handling.
Faster
The downtube, front fork, and seat tube have
been widened for a more aerodynamic design.
Wind tunnel testing
Wind tunnel tests show: C5 Aero is 4.6W more efficient and 5 minutes faster over a 100km ride with a 40km/h crosswind.
X-ray Inspection
We use precise X-ray inspection to ensure
quality, with interlayer gaps smaller than
1x10mm for dependable durability
