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.
