Specialized Fatboy Comp Carbon review

May 2016 · Seb Stott

Despite a couple of component niggles, the Fatboy has huge potential to dominate any fat bike race. Buy if you want a fast, capable and well-appointed fatty to race with

Highs
  • Light, speedy, well finished and perfect for mile-munching

Lows
  • You'll want to switch the stock tyres for snow, 203mm rotors are overkill, gearing is a little narrow
