Polygon DH7 – Downhill Speed Without the Hefty Price Tag
The Polygon DH7 is built to send it—without sending your wallet into a tailspin. Designed for serious downhill riders who want race-ready performance at an unbeatable price, this beast features a mullet wheel setup (29” front, 27.5” rear) for the perfect blend of speed and agility on gnarly descents.
A RockShox Boxxer Base 200mm fork and plush rear suspension soak up big hits with ease, while TRP DH-R EVO brakes deliver the stopping power you need when the trail gets wild. The SRAM GX DH 7-speed drivetrain keeps shifting crisp and reliable, so you can focus on picking the fastest lines.
With a dialed spec, solid performance, and an unbeatable price, the DH7 is ready to rip—no excuses.

We recommend confirming the specifications with your local Evo Cycles showroom if you have any questions.
