Summary

The Specialized Fuse is a highly capable cross-country bike that excels in climbing and handling, offering a unique blend of fatbike-like traction and trail bike-like agility. Its playful geometry and reliable components make it a fun and economical choice for riders looking to tackle a variety of trails without the maintenance of full suspension. While the 6Fattie tires provide excellent traction, they can feel sluggish compared to narrower options, and some components may not meet expectations for the price.

Pros
  • Climbs incredibly well

  • Fatbike-like traction and trail bike-like handling

  • Playful and easy to coax from one corner to the next

  • Well-constructed aluminium frame

  • Reliable, economical parts

Cons
  • 6Fattie tires are a little sluggish compared with normal 2.3-inch-wide rubber

  • Rear tyre prone to sliding out on corners

  • Raidon fork is a spec disappointment for the price

Long Term Review: Specialized Fuse Expert Carbon 6Fattie mountain bike

Feb 2017 · John Herron

Specialized has peppered it’s lineup with “Plus” bikes, and its Fuse lineup is helping bring new life to the hardtail by combining trail bike nimbleness with near fat bike traction. Using modern trail bike geometry and a dropper post, the Fuse rides a lot like a small-travel full suspension rig. I didn’t expect to be this …

Tested: Specialized Fuse Expert 6Fattie

Jun 2015

3″ tyres on mountain bikes. Yes, ‘semi fat’ is now officially a thing. Get used to it, we’ll be seeing ‘semi fat’ bikes popping up a lot as we roll toward 2016. The new standard will surely provoke heated discussions and much throwing of hands in the air. But for now we’ll cast all opinions …

Highs
  • Boat loads of fun.

  • All the excitement of riding a hardtail.

  • Traction!

  • Corners and climbs anything in its path.

Lows
  • Sluggish on buff trails.

  • Clunky Manitou fork.

  • Pricey for the spec.
