The Roscoe 9 is our best all-mountain alloy hardtail, built for lap after lap of grin-inducing fun. A 140 mm FOX Rhythm 36 fork, powerful 4-piston brakes and a fast-and-grippy wheel and tyre combo deliver incredible capability whether you're nailing jumps or picking through gnarly rock gardens.
It's right for you if...
You love the serious fun and connected feel a hardtail brings to the trail, and you want one that’s spec’d with top-notch parts that love rough and tumble runs as much as you do.
The tech you get
A lightweight aluminium frame, a 140 mm FOX Rhythm fork with beefy 36 mm stanchions, a Shimano SLX/XT 1x12 drivetrain with a wide range of gears for climbing, powerful 4-piston brakes and a dropper post for room to move around on the bike on descents, corners and jumps. Plus, fast-rolling 29er wheels and wide, grippy 2.6" tyres.
The final word
Rip laps, catch air and crush techy descents on our best hardtail. Of all the rad parts on this bike, the FOX Rhythm 36 fork is the best upgrade – it’s capable of soaking up even the roughest lines.
