Backed by Polygon’s racing heritage, the 2025 Collosus DH7 takes downhill innovation to new heights with massive 200mm air-sprung travel, a softer rear shock, refined geometry, and a striking new design that screams speed.
Whether you’re lining up for the next UCI event or hunting personal bests at your local bike park, the DH7 is tuned to keep you pinned and confident all the way down.
Unleashing the New Innovations of the 2025 Collosus DH7
The 2025 Collosus DH7 Downhill mountain bike pushes the envelope of extreme terrain domination with a series of bold, race-proven upgrades:
- 200mm Travel with Advanced Air Spring Technology: At its heart, the Collosus DH7 delivers a monstrous 200mm of plush, highly tunable travel.
Polygon’s new air-sprung system replaces the traditional coil, offering a lighter feel and more adjustable ramp-up for riders who demand precision over the gnarliest drops and rock gardens.
This setup gives racers an edge in big-hit control without compromising sensitivity.
- Softer Rear Shock for Uncompromising Grip: To pair with the air-sprung fork, the rear shock is re-engineered with a softer tune, ensuring superior traction when pounding through technical chunder or high-speed berms.
It’s a setup made to hold your line and stay planted, even when the trail wants to throw you off.
- Refined Geometry for Progressive Descending: Downhill confidence is all about angles, and the 2025 DH7 has them dialed.
With a slacker head angle, extended reach, and lower standover height, this bike is purpose-built to keep you centered and in command while navigating steep, unpredictable terrain. It rewards aggressive lines with a planted, unstoppable feel.
- Striking New Design Language: Beyond performance, the latest Collosus DH7 turns heads with its bold new look.
Polygon has introduced fresh paintwork and reworked tube profiles that not only improve frame stiffness but also sharpen the bike’s unmistakable downhill silhouette.
With these powerful innovations, the Collosus DH7 is no longer just race-ready; it’s race-dominating.

Collosus DH7 Performance: Commanding the Steepest Trails

From the first drop-in, the 200mm air-sprung travel feels bottomless yet supportive, absorbing savage hits while keeping the chassis calm and composed.
Riders reported incredible confidence thanks to the balanced leverage curve of Polygon’s IFS 6-bar suspension, which holds traction like Velcro even across slick roots, loose shale, and blown-out landings.
The mixed-wheel setup (29” front, 27.5” rear) gives the DH7 unbeatable agility through switchbacks while keeping the front end rolling over square-edge impacts with unstoppable momentum.
Combined with a slacker head angle and extended reach, the bike stays planted and stable even at warp speeds.

With its advanced IFS 6-bar suspension, air-sprung 200mm travel, and proven SRAM GX DH drivetrain, the DH7 holds its own against high-end downhill rigs that often cost thousands more.
Polygon’s approach to value is clear: no compromises in suspension kinematics or braking confidence, but without inflating the price.
Whether you’re an experienced downhill racer looking to replace an aging platform or a gravity-focused rider wanting a serious World Cup-capable chassis without paying a World Cup salary, the Collosus DH7 should be at the top of your shortlist.
