Specialized Fuse

The Specialized Fuse is a hardtail bike. It is perfect for new mountain bikers who don't want to deal with the high costs of purchasing and maintaining a full-suspension bike.

The Specialized Fuse has a sleek design and durable frame.

You can choose between 27.5" & 29" wheels. These offer better traction and comfort on rough terrain.

The bike's hydraulic brakes provide excellent stopping power.

The Specialized Fuse is a heavy bike.

The different bike sizes may not be a good fit for those they are designed for. The XL bike, for example, may feel cramped if you're tall.


The Specialized Fuse is a hardtail bike. Hardtails are bicycles that only have front suspension. You can use them on any terrain, but they perform really well off-road. So if you buy this bike, you should do some mountain biking with it.

If you’re not looking to buy a hardtail bike, check out our review of the Diamondback Atroz. A full-suspension mountain bike that goes for under $1000 (really good price for a full-suspension bike).

Specialized has three Fuse bike models. These are the Fuse Expert 29, Fuse Comp 29, and Fuse 27.5. For example, all the Fuse bikes have the same design and a Specialized aluminum frame. The three bikes also all have RockShox suspension. However, they have different cranksets. The Fuse Expert 29 has a Sram NX Eagle, DUB. The Comp 29 has an SRAM SX Eagle, 170/175mm, and the Comp 27.5 has Stout, forged alloy, 76mm BCD crankset.

The prices also vary. The Fuse Expert 29 is the most expensive bike going for $2,150. It has the best features in the Fuse series. The Comp 29 and Fuse 27.5 sell for $1,675 and $1,250 respectively.

Who is this bike perfect for?

  • If you're looking for a versatile bike, you should consider buying the Specialized Fuse. With some slight tweaks, this bike can be a commuter, touring, or any type of bike you want it to be.
  • If you're getting into mountain biking, top mountain bikers recommend starting with a hardtail bike to learn the fundamental skills of the sports. So you can get this hardtail as your first mountain bike.

Specialized Fuse


The Specialized Fuse is a really smooth and comfortable bike to ride. This is made possible by:

  • The 'one by' drivetrain makes shifting of gears easy and fast as you cycle.
  • The fat tires on this bike give you plenty of grip on muddy terrain and provide decent cushioning on rock surfaces.
  • Hydraulic brakes make you confident that you can come to a quick stop in all weather conditions and terrain.
  • Specialized bike saddles are known for being comfortable, and the seat on the Fuse doesn't disappoint. You can go for miles without feeling the need to stop to get off an uncomfortable saddle. A dropper post makes it possible to adjust your seat as you change terrain, so you won't have to stop to change the seat position using the seat clamper.
  • The Specialized Fuse is a heavy bike primarily due to its tires. The weight does make it slow to pick up speed. But if you're not looking for a racing bike, the Specialized Fuse will be fast enough for you.


We recommend buying the Specialized Fuse if you're looking for an entry-level, reasonably priced, durable, comfortable, and low-maintenance bike that can handle challenging terrain. This bike will serve you well as you save up and consider options for a premium bike.
