Real-World Performance You Can Feel

From the very first ride, the Helios A7 Di2 makes its performance pedigree clear. Built on Polygon’s advanced ACX carbon frameset, the bike strikes an ideal balance between lateral stiffness and vertical compliance. 

That means when you’re powering through a climb, sprinting down the flats, or tackling uneven pavement, the frame responds with precision, delivering your energy straight into forward motion while still soaking up the vibrations of rough roads.

Out on the road, it’s not just about raw speed—it’s about control. The 28c Pirelli Pzero tires offer a confident grip through sharp corners, unpredictable pavement, and long-distance rides, giving you better acceleration and stability without slowing you down. 

And when it’s time to descend or navigate sketchy conditions, the Shimano 105 hydraulic disc brakes step in with consistent, powerful stopping power. You’ll feel in control whether you’re braking late into a tight turn or feathering the levers down a fast descent.

The real magic, though, lies in the Shimano Di2 electronic shifting. With a light tap, the gears click instantly and precisely—no hesitation, no missed shifts—even under full load during a sprint or climb. 

It’s a level of smoothness and accuracy that quickly becomes second nature, letting you stay focused on the ride, not the mechanics.
