Product ID: 1172333

The perfect starting basis for a highly capable trail bike that can climb efficiently and descend the gnarliest trails, Trek’s Fuel EX Alloy 29" Mountain Bike Frame has 130mm of travel and some innovative features.

The Mino Link chip enables the geometry to be switched between two settings depending on rider preference or the terrain and the Knock Block prevents the fork crown from ever hitting the frame.

Trek Fuel EX Alloy 29" Mountain Bike Frame 2020

Versatile and fun, Trek’s Fuel EX Alloy 29" Frame can be built up into a Mountain Bike that can climb, descend and race through twisty singletrack without breaking a sweat, making it an ideal one bike for everything option. The FOX Performance FLOAT EVOL rear suspension provides 130mm of travel, with the RE:aktiv 3-position damper helping keep the rear wheel in contact with the ground for better traction and the platform efficient for pedalling. The Mino Link in the rocker can be flipped over to lower the bottom bracket and slacken the head tube for a more stable ride with slower handling and the Active Braking Pivot (ABP) rear triangle design maintains the suspension’s suppleness under braking. The clever Knock Block system stops the handlebar or fork crown from being able to hit the frame in the event of a crash by limiting the degree to which the steering can turn.


  • Alpha Platinum Aluminium frame with variable geometry Mino Link, ABP and Knock Block protection, 130mm of travel
  • Optimised for 29” wheels, using Boost spacing
  • FOX Performance FLOAT EVOL rear shock with RE:aktiv 3-position damper
