"Way ahead of the pack"
"The faster our test riders pushed, the better the bike felt, inspiring more confidence than a bike in this suspension category should. Fuel EX makes a strong argument for itself as a do-it-all trail machine that is pure fun to rip."

"Trek has elevated the Fuel EX's performance even further. This latest iteration feels just as quick on the climbs, but when it's time to descend, it's less phased by steep and technical trails than ever before."
Read more"A bike with fire in its belly"
"A trail hammering speed machine, lightweight, incredibly well built, and so beautifully constructed. A genuinely quick and balanced trail bike that's bang up to date in angles and ride dynamic."
Read more"Right on the money"
"Whether you're a seasoned rider or just getting into it, Fuel EX makes everything feel easier. It rockets up climbs, slays the descents, and scorches singletrack at an eye-watering pace."

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.

Boost148/110
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.
G2 Geometry
Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability. We call it G2 Geometry, and it's why our 29ers handle better than anyone's.
