With the all-new Specialized Fuse range, more volume means more speed, and its obvious right from the off. The development of the 6Fattie wheel system puts out more traction, more floatation and better handling without sacrificing anything to efficiency on the climbs.

Constructed out of M4 Premium Aluminium, a lightweight yet durable frame has been produced with low and slack geometry for an agile but stable ride through trails, descents and climbs. The frame also features Specialized’s exclusive Diamond Stay that accommodates the 6Fattie wheel and tyre whilst keeping short chainstays that provides a nimble ride. Set-up with a SR Suntour Raidon front fork that delivers 120mm of travel and a 1x10 drivetrain, the Specialized Fuse HT Comp 6Fattie is the ultimate trail hardtail.

To create the perfect trail experience, you need a little of everything. Climbing, descending, motoring over root and rock sections—the geometry needs to lend itself to doing it all. Our Trail Geometry was developed with this knowledge at the forefront of the design, and year after year, we keep perfecting on perfection. It all starts with handling, which is why you'll find roomy top tubes and slack head tubes that inspire confidence over any terrain. And to ensure maximum efficiency, our Trail Geometry always features the short chainstays to enhance power transfer, while also keeping the rear end nice and tight for nimble handling.
It goes without saying that more traction and floatation equates to more control, speed, and ultimately, more fun. And with our 6Fattie tires, this is exactly what you get. 6Fattie tires experience an increase in tire volume by 56%, which equates to more floatation, while allowing for lower pressures to be run. This means that, compared to regular mountain tires, 6Fatties will better absorb bumps without slowing you down. The tire's ample size also means that its contact patch is increased by 69%, so this way you'll experience more traction for more control in the corners. More traction, more control, and more floatation equals more fun.
Having the ability to raise and lower your saddle height on-the-fly is a complete game-changer, and no dropper seatpost outperforms our mechanical Command Post IRcc. By allowing you to fine-tune your saddle height, our Command Post increases your efficiency on climbs, while providing you with more control on the descents. Action is controlled by our Single Ring Lever, and there are 10 middle positions that allow you to fine-tune your position for every trail condition. Making the adjustments is intuitive and easy, which means that you'll always find yourself in the right position for the trail ahead.
