It's right for you if...
You already love the fat bike scene, and may even already own a hardtail fat bike, but now you're cashing in all your chips to get the most capable fat bike frame we offer.
The tech you get
A lightweight OCLV Mountain Carbon main frame with trail-tough alloy stays, 120mm of travel with a FOX Performance Float EVOL shock, FSA headset. Built for PF121 bottom bracket and 27.5˝ or 26˝ wheels, with a maximum tyre width of 3.8˝ on 27.5˝ wheels, and 4.5˝ on 26˝ wheels.
The final word
Farley EX C is a carbon fat bike frameset with a do-anything attitude and the performance to back it up. Warning: don't stand too close to this bike, because it can (and will) plough over whatever gets between it and a good time.
