Trek Fuel EX 5 27.5" Disc Mountain Bike

Step up to more confident trail riding with the Trek Fuel EX 5 27.5" Plus Disc Mountain Bike. With 140mm travel RockShox Recon RL suspension at the front and 130mm travel RockShox Deluxe RL rear for tackling rock gardens, technical descents and even small drop-offs, there will be few trail obstacles that stand in your way. Mid-fat 2.8" Schwalbe tyres will feel pinned to the trail or the lip of the berm when descending at pace and will have traction for pushing on and carrying momentum into sharp climbs as well. With the exclusive Mino Link adjustable geometry you can fine-tune the head angle by 1/2 a degree and drop the bottom bracket by up to 10mm to really slacken off the ride, without affecting trail performance or suspension response.

A 1x10 Shimano Deore drivetrain with 30T chainring keeps things simple at the front and an 11-42 cassette will spin up just about any climb or make the ride back up the fire-road to the trailhead nice and easy.
