Polygon Helios A8 – Electronic Shifting, Carbon Everything
The Polygon Helios A8 is precision engineering meets race-day performance. Built for riders who demand the very best, this carbon road machine features a full carbon frame, fork, and wheels, paired with the legendary Shimano Ultegra Di2 2×12 electronic groupset. Every detail is optimized for speed, efficiency, and instantaneous shifting.
The Ultimate Carbon Package
Weight is the enemy of speed, and the Helios A8 fights back with a complete carbon construction. The high-modulus carbon frame is incredibly light and stiff, transferring every watt of your power directly to the road. The full carbon fork slices through the wind and absorbs road buzz, while the carbon wheels reduce rotational mass for quicker acceleration and climbing.
Wireless Precision with Ultegra Di2
Say goodbye to cable stretch and missed shifts. The Shimano Ultegra Di2 2×12 electronic groupset delivers crisp, instantaneous gear changes at the touch of a button. Whether you’re sprinting for the line or grinding up a steep climb, the shifting is flawless every time. The 2×12 gearing provides a massive range, ensuring you always have the perfect cadence.
Aero Advantage
The Helios A8 isn’t just light—it’s slippery. The truncated airfoil tube shapes and integrated cable routing reduce drag, helping you cut through the wind with minimal effort. Every tube is sculpted to balance aerodynamics, weight, and ride quality.
