POLYGON Collosus N9 Full Suspension Mountain Bike

Replacing the much-lauded XQUARONE and featuring the IFS 6 bar linkage rear suspension design developed for the Mt Bromo ebike, the Collosus is a new Enduro bike with an enviable pedigree.

This 29ers burly design is indicative of a bike that smashes through hair-raisingly steep and rough trails like a downhill bike. The bike’s plush FOX suspension and 2.6-inch-wide Schwalbe tyres serenely smooth out the trail and allow the bike to grip, then grip and grip some more. You will lose your nerve before it loses traction! The N9’s geometry, with its slack head angle and plenty of reach, enhance the bike’s stable feel.

This isn’t a lightweight bike, it's an alloy frame with a big FOX 38 fork after all, but the Collosus is an efficient pedaller and a capable climber, so you don’t need to fear the ascents. It almost feels like the N9’s Shimano XT drivetrain is a footnote, but this is one of the most precise gearing options that money can buy.

Polygon’s Collosus N9 is an extraordinarily good value Enduro bike that has proven itself on the World stage. It’s a serious piece of equipment for fast, adrenaline fuelled riding on technical trails and bike park laps.
