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.
Fuel EX 9.7 is our most affordable full suspension carbon trail bike. It pairs a lightweight, smooth-riding frame with a beefy 140mm FOX 36 fork, SRAM NX Eagle drivetrain, and powerful 4-piston brakes for a fast, fun mountain bike that's a ripper now, and ripe for upgrades later.
It's right for you if...
You want one carbon trail bike that can take on every adventure, from flowy singletrack to the gnarliest descents and most brutal climbs. You don't mind sacrificing a little on the parts so you can get the best frame right now.
The tech you get
A lightweight and stiff full OCLV Mountain Carbon frame with internal storage, a 140mm FOX Rhythm 36 fork, 130mm of rear travel with a FOX Float Performance rear shock with Trek's efficient RE:aktiv damper, a wide-range 1x12 SRAM NX/GX Eagle drivetrain, a Bontrager Line dropper post, and powerful Shimano 4-piston hydraulic disc brakes.
The final word
Full suspension control on a lightweight and trail-tough carbon frame makes for a fun and fast ride. It's rugged enough for rowdy descents, but still spry for lively climbing and accelerating.
