Trek Farley AL Frameset

Farley AL is a great-value platform for your next fat bike. This lightweight Alpha Platinum Aluminium fat bike frameset has the handling of a traditional trail bike with all the monster-truck capability that comes from oversized tyres.

• Farley Carbon fork
• Alpha Platinum Aluminium frame
• Claimed weight M - 3.95 kg

Highlights

• A fork ready for any adventure: Farley's new OCLV carbon fork positions you perfectly over the front wheel, increasing traction on rough terrain while allowing a shorter stem. The custom rack mount on the crown and carefully positioned triple bottle cage mount (64mm spacing) let you fit all the equipment you need without sacrificing handling.
• A better way to produce aluminium: Starting in 2024, we began replacing traditional aluminium with aluminium with a reduced carbon footprint, produced using renewable energy. By October 2025, nearly all the aluminium bikes produced, including this one, had made the transition, significantly reducing our environmental footprint.
