Trek Farley 5 (2027) - Fat Bike

Trek Farley 5 in Satin Blue Sage to Lithium Grey Fade

1/12

The ride, not just the specs

Snow, sand, anywhere.

Farley is a fat bike, made for riding where other bikes can't: snow, sand, mud, and soft trails.

It turns winter into riding season and makes every trail an adventure.

What makes it special

Thoughtful details. Big possibilities.

01
Fat and fast
27.5″ fat tires give you the best combo of all-terrain grip, stability, flotation, and fast-rolling speed
02
Adventure-ready fork
Farley's new, short-offset OCLV carbon fork puts you in an optimal position over the front wheel, upping traction over sketchy terrain while allowing for a shorter stem. A custom rack mount on the crown and thoughtfully positioned triple bottle bosses (64mm spacing) on the lower legs let you gear up without sacrificing handling. Protective rubber bumpers on the bottom of the fork legs keep Farley upright and manageable when the front wheel needs to come off.
03
Haul of the wild
Mounts all over the frame let you carry a wide variety of gear with endless customization options. Gummy bears? Extra layers? Camping gear? Haul it all.

Good to know6

Trail-ready gear Deck out your Farley Alloy with our favorite compatible accessories
Dropper post Use the remote lever to lower your saddle so it's out of your way when you're descending and cornering.
Tubeless Ready wheels & tires Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. Just add TLR rim strips, valves, and sealant.
Internal cable routing We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
Rapid Drive 108 rear hub With 108 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky climb.
Blendr-compatible stem Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.
