Trek Fuel EX AL Gen 5 Frameset Mountain Bike
Will my bike have a curved top tube?
Smaller frames (XS and S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
RE:aktiv
RE:aktiv technology gives you firm support for efficient pedaling that instantly gives way for smooth control when the trail turns rough.
Straight Shot w/Knock Block
Trek’s Straight Shot frame design optimizes the stiffness-to-weight ratio for a more responsive ride. You’ll be able to push harder and stay more planted on your line when the going gets rough.
