Specialized Fuse Expert 6Fattie Mountain Bike 2017

Designed to take on the trail, the Specialized Fuse Expert 6Fattie Mountain Bike 2017 is ready to conquer anything you throw at it. Rock gardens, steep descents, technical terrain with tight switchbacks, you name it, the Fuse Expert 6Fattie 2017 can handle it.

Constructed with Specialized’s M4 Premium Aluminium, the frame is lightweight, durable and provides responsive handling to maneuver along the trail. The low and slack geometry enhances the frame's capabilities when off-road; giving the rider greater confidence to attack steeper sections that may otherwise be deemed unrideable with a more upright position on the bike.

This doesn’t affect the Fuse’s ability to climb, though. Specialized have used their renowned Diamond Stay that allows their bikes to accommodate larger tyres, without sacrificing snappy handling and climbing prowess, otherwise lost in other fat tyres specific bikes.

The fork is a Manitou Magnum Comp 650+ fork with 100/120mm of travel to soak up all trail bumps and big hits, furthering the Fuse’s on-trail versatility. The adjustable rebound allows you to dial in your preferences, meaning the bike will ride the way you want it to, not how the manufacturer set it up.

Enhancing the grip and control of the Fuse are the 650b x 3.0” 6Fattie tyres. These tyres sit in between fat bike tyres and regular mountain bike tyres, providing the best of both worlds with a greater level of grip in the corners and fast, rolling consistency on the straights.

Using a SRAM GX rear derailleur boasts a great range of gearing, giving you the option to spin up climbs or attack the technical gradients. The one-by chainring design allows prevents chain slip and reduces the overall weight of the bike.

Finished off with a TranzX YSP03 dropper post to give the manoeuvrability of chopping and changing riding position at a moment's notice, depending on the trails layout ahead, makes the Fuse Expert 6Fattie Mountain Bike 2017 one of the most versatile and highly-performing mid-size fat bikes out there.


  • M4 Premium Aluminium proved to be the right material for the job, allowing a lightweight, durable frame with a low and slack geometry that's equal parts snappy and efficient on climbs and descents. It also allowed Specialized to incorporate their exclusive Diamond Stay that accommodates the 6Fattie wheels/ tyres without compromising their hallmark short chainstays that provide unrivalled handling and climbing prowess

  • A Manitou Magnum Comp 650+ fork pairs 100/120mm (size-specific) of smooth travel with adjustable rebound for maximum absorbency over harsh terrain and easy, on-the-fly adjustments to the damping to hit the perfect tune

  • Custom WTB Scraper i45 wheelset has a fat 45mm width and alloy construction for the perfect blend of speed and strength, which means that you'll experience less deflection, increased traction, and more stability—all at lower tyre pressures

  • 650bx3.0" 6Fattie Ground Control tyres feature a perfectly sized contact patch for life-changing levels of traction and control while cornering, all without sacrificing climbing efficiency or descending prowess

  • Specialized’s Stout XC Pro crankset would be the perfect complement to any one-by drivetrain, but here, its strong alloy construction makes it ideal for power transfer on climbs and the inevitable rock-strike when descending through technical gardens
