Polygon Helios A9X Entity WR5 Road Bike: Specs, Price, colors & Features

The Polygon Helios A9X Entity WR5 leans toward precise control and fast response, aided by the Shimano Dura Ace ST-R9270 Di2 electronic shifting. Each gear change feels deliberate, with the 12-speed range managed efficiently through the Shimano CN-M8100 chain. On long stretches or steep climbs, the shifting remains crisp without hesitation. The frame geometry allows for an aggressive riding posture suited for competitive pacing. Whether on flat roads or twisting descents, the overall setup rewards cadence and timing over brute strength.
