Trek Farley 5


SKU: 37018 Category:


The Farley 5 is the ultimate go-anywhere fat bike. Arctic tundra? Farley’s game. Sandy desert singletrack? Farley’s lofty tyres will keep you afloat. A winter bikepacking mission through rugged terrain? Sounds like a walk in the park. The Farley’s all-new geometry is more capable than ever with a slacker head tube angle for more stability and a steeper seat tube angle for pedalling efficiency and comfortable reach. Up front, its carbon fork is loaded with a variety of mounts, so you’ll be able to load up gear for the adventure of your dreams.

You don’t want to limit your adventures to one season. Come snow, sand or singletrack, you’re ready to rip and want a bike that can handle it all. You like your days long, and your adventures longer. You appreciate the thoughtful details, like plenty of mounts for hauling a week’s worth of gear to keep you going far beyond the last lamp post.

A rugged alloy frame with all-new geometry that’s built to handle it all. Huge 4.5-inch tyres that keep you floating over snow, sand, mud and dirt. A carbon fork with plenty of mounts for loading up racks and bags. An internally routed dropper post that lets you get behind the saddle on descents. A wide-range 10-speed Microshift drivetrain with a big cog for taking the sting out of steep climbs when your bike is fully loaded.

For the explorer who knows no bounds, the Farley 5 is the perfect go-anywhere adventure machine. It’s built for you to choose your own adventure and load it with all of the racks and bags you need to get you there.

– It comes with a carbon fork that has lower leg mounts for gear cages, mounts for our custom front rack and rubber bumpers to protect the dropouts when the front wheel is removed.
– Its huge 4.5-inch tyres will keep you floating over snow, sand, mud and dirt,
– The new progressive trail geometry feels more capable and confident than ever.
– The internally routed dropper post lets you move around on the bike and get behind the saddle on steep descents.

Fat and fast
27.5″ fat tyres give you the best combo of all-terrain grip, stability, flotation and fast-rolling speed

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 customised rack mount on the crown and thoughtfully positioned triple bottle bosses (64 mm spacing) on the lower legs let you gear up without sacrificing handling. Protective rubber bumpers on the bottom of the fork legs keep the Farley upright and manageable when the front wheel needs to come off.

Haul of the wild
Mounts all over the frame let you carry a wide variety of gear with endless customisation options. Gummy bears? Extra layers? Camping gear? Haul it all.

Keep it clean
Internal routing helps to protect Farley’s components from the elements and makes it easy to mount gear

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.
