Fatboy Comp Carbon
2018 Fatboy Comp Carbon
Every now and again, we're all faced with going on a diet, and the same is true for our Fatboy. With the new Fatboy Comp Carbon, we've elevated the fat bike platform to a higher level of performance, strength, and efficiency.
It features a sophisticated 10m carbon construction that's lightweight, ultra-compliant, and stiff in all the right places for the climbs. The layup also allowed us to integrate internal cable routing to keep things clean and simple through nasty conditions.
Sprinkle in a durable one-by drivetrain and some near bombproof alloy wheels, and you have a bike that will give new purpose to winter and more fun to springtime.
