Specialized Fuse 27.5 Mountain Bike 2021

The Specialized Fuse 27.5 Mountain Bike is a rowdy hardtail that doesn't shy away from rough trails and is more than comfortable on social gravel rides. The A1 Aluminium chassis is tough, with a lower, more aggressive position and wide-diameter downtube to amp up stiffness whilst the low-slung downtube ensures responsive handling and agility on more technical trails.

Maintaining control at speed is a cinch thanks to the 27.5 Shimano MT400-B wheels, which heighten stability and traction alongside the grippy Specialized Butcher tyres. 130mm of travel is provided by the RockShox Judy Silver TK fork, which soaks up bumps when rolling over roots, rocks or potholes, should the route factor in any questionable tarmac sections.

11-speed Shimano Deore components promise rugged reliability when venturing onto choppy trails and provide enough gearing options to keep the legs spinning as gradients steepen. Sending weight back and low over the rear wheel is made simple by the TranzX Dropper seatpost, which gets the saddle out of the equation when tackling sweeping corners or technical descents, whilst the slack head angle also heightens descending confidence. Lending swift and responsive stopping power are Shimano BR-MT200 hydraulic disc brakes, which perform reliably come rain or shine.
