GEO
With endurance road geometry, the S5D offers a blend of comfort with aerodynamics and speed. It features flexible/dropped stays for comfort and vibration-dampening, a racey yet forgiving 73° head tube, a comfortable 74° seat tube, low stand-over height for easy access and a long wheelbase for added stability.

ALLOY TECH
Aluminum has long been the ideal material for bikes and aeroplanes with its incomparable strength-to-weight ratios. Polygon started with 6061 triple-butted tubing and heat treating for strength and durability and finished it off with internal cable routing and a tapered/semi-integrated front end.
