  • Adventure-ready fork

    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.

  • A better way to produce aluminum

    A better way to produce aluminum

    Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.

Overview

Farley AL is a high-value platform for your fat bike build. This lightweight Alpha Platinum Aluminum fat bike frameset has the ride characteristics of a traditional trail bike, with all the monster truck capability that comes with fat bike tires. Plus, you get tons of mounts for adding accessories like racks, fenders, and gear cages.
