Polygon’s long-anticipated downhill MTB has finally arrived, and Pinkbike has taken it for a full-gas first ride. After nearly two years of prototype sightings under Mick Hannah and the Polygon UR Team, the 2015 Polygon Collosus DH9 is officially ready for the public.
With 203mm of travel, 27.5-inch wheels, and a race-proven frame layout, Pinkbike’s early review shows one thing clearly: Polygon has delivered a seriously capable Downhill Mountain Bike at a price that’s causing riders everywhere to take notice.
A Price and Spec List That Stopped Pinkbike in Its Tracks
Pinkbike’s first reaction? Shock, because the 2015 Collosus DH9 arrives with a full Shimano Saint groupset, FOX 40 FLOAT fork, FOX DHX2 rear shock, and e*thirteen wheels, all for just $5,499 USD.
In an era where premium Full Suspension Mountain Bikes often climb well beyond the five-figure mark, Pinkbike highlights the Collosus DH9’s value as “the biggest reason riders will take a second look.”
With a second model, the DH8 priced at $3,999 USD, Polygon clearly aims to make high-performance MTB Bikes more accessible without sacrificing capability.
Race-Born Engineering: A Frame Designed for Downhill Performance
Pinkbike notes that the 2015 Collosus DH9 wasn’t designed in isolation. It represents years of testing with the Polygon UR Team across the world’s toughest courses.
The bike uses a floating dual-link suspension system, placing the shock between two triangular links while maintaining stiffness and balance.
One detail Pinkbike emphasizes is the geometry adjustment chip, allowing riders to switch between 27.5” and 26” wheels while maintaining consistent handling.
Combined with a burly aluminum front triangle and a carbon swingarm, it results in a frame that feels precise, aggressive, and ready for competition—qualities essential for a modern Downhill MTB.
Ride Impressions: Quick, Playful, and Effortlessly Maneuverable
Testing the bike at Whistler’s Garbanzo zone, arguably one of the harshest proving grounds in the world. Pinkbike describes the 2015 Collosus DH9 as quick, lively, and undeniably playful.
According to the review, the short front center paired with a 30mm stem gives the bike “a cockpit that feels compact but extremely responsive,” making it easy to whip through tight technical sections, roots, and rock-filled chutes.
This agility is an advantage for riders seeking a Mountain Bicycle that rewards precision and dynamic riding.
Pinkbike also mentions that Polygon offers four sizes, including XL, which gives riders flexibility to choose their preferred reach and stance.
Balanced Suspension With World Cup DNA
Whether on natural rock-and-root trails or smoother jump lines, the 2015 Collosus DH9’s suspension impressed Pinkbike with its balance and support.
The rear end delivered solid tracking with no noticeable flex—an important highlight for a Full Suspension Mountain Bike designed for racing and freeride terrain.
Pinkbike notes that on extremely rough, high-impact sections, the FOX DHX2 shock used its final portion of travel more readily than expected.
The Polygon UR Team often chooses air shocks for a more progressive feel, and Pinkbike suggests this as an easy tuning option for riders who want even more bottom-out resistance.
Still, the overall verdict remains strongly positive: the 2015 Collosus DH9 feels composed, controllable, and ready to tackle the demands of aggressive downhill terrain.

With its race-inspired geometry, dialed suspension layout, and standout value, Pinkbike believes many riders will be adding the Collosus DH9 to their wishlist this season.
