The tech you get
A lightweight aluminium frame with internal routing to protect your cables and add to the bike's sleek look, an upgraded 9-speed Shimano CUES drivetrain, a wide range of gearing so you always have the right gear for your terrain, powerful hydraulic disc brakes and a terrain-smoothing suspension fork with a lockout.

Why you'll love it
- The Marlin Gen 3 gives you serious trail capability, with big tyre clearance and slack, confidence-boosting geometry that keeps you stable from singletrack to city
- Rack and mudguard mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter
- Its ThruSkew system is safer, simpler and stronger, plus it makes removing the rear wheel easy for flat fixes in a hurry
- Internal routing makes it easy to add a dropper post that lets you lower your saddle on the fly for more confident descending
- Marlin models in sizes XXS and XS have a curved top tube and lower standover height that makes it easier for smaller riders to mount and dismount
