Specialized Fuse Expert 29" Mountain Bike 2022
Rugged and nimble, the Specialized Fuse Expert 29" Mountain Bike is a hardy trail riding steed that is rapid down jump and berm filled descents but more than spritely enough to climb back up again. The M4 aluminium frame is light but strong and has a super-wide diameter down tube to ensure a solid pedalling platform. Its low slung top tube affords excellent manoeuvrability, while the precisely shaped seatstays afford plenty of room for plush 29x2.6” tyres.
A FOX FLOAT 34 Rhythm fork partners the frame, using its 130mm of suspension to improve comfort, line accuracy and control over the most rugged terrain. The geometry includes a long reach, slack head angle and steep seat angle to guarantee perfect weight distribution, confident handling and efficient power transfer. A smooth-shifting, wide-ranging SRAM GX Eagle 12-speed gear configuration turns sturdy, robust wheels that soak up the biggest hits with ease, and 4-piston hydraulic disc brakes grant power and control when the riding is at its most extreme. A Trans-X seatpost completes the build, dropping the saddle out of the way on the fastest, most technical descents.
