We're always striving to be at our best and push our model ranges as far as possible, the Fatboy Comp Carbon has under gone a few changes and you can expect an even higher level of performance, strength and efficiency from this popular model.

Equipped with our exquisite FACT carbon fibre construction this frame is lightweight and very stiff where needed. Even better, we've included internal cable routing, to ensure all the slush, sand, snow or dirt will take no effect on your vitals or performance out in the elements.

You'll also notice we've used our FACT carbon fibre fork which provides tons of compliance and reduces chatter out on the trail whilst keeping the overall weight of the bike down; brilliant.

By using Alloy rims laced to our XC Pro hubs, the Fatboy Comp Carbon rides on a wheelset that's dependable, rugged and efficient. Whether you're hitting the trail or exploring in the harshest conditions such as snow, you can trust our Fatboys.
