Take a look at the world's strongest man, and you're not going to find some chiseled Adonis. You're going to find someone who has more volume. The Mountain, anyone? Behind the "extra" surface area, though, there's a man that can dominate a caber toss and run down the tarmac with a plane in tow. Mathematically, it could be broken down as more volume + versatility = dominance, and that's exactly what's at play with the Fuse Comp.

These bigger tires put out more traction, more floatation, and better handling without sacrificing anything to efficiency on climbs. And with this model, we spec'd it with a no-nonsense build that's handpicked to get the job done. Components like a dropper post, and a buttery-smooth, 120mm RockShox Recon RL fork ensure that, no matter how rugged, technical, or hair raising that job might be, the Fuse can handle it with ease.

  • M4 Aluminum with Smooth Welds 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 us to incorporate our exclusive Diamond Stay that accommodates the 27.5+ wheels & tires without compromising on our hallmark short chainstays.
  • A RockShox Recon RL fork handles suspension duties up front with 120mm of plush travel, and the Motion Control™ damper makes sure you climb and descend with the utmost of efficiency.
  • SRAM's 11-speed NX groupset features a wide gear range that delivers tons of climbing and descending efficiency.
