A couple months ago, I was on the hunt for a new mid-travel personal bike and found myself largely unconvinced by most of the offerings on the market. Then a new, highly adjustable and longer in the tooth Trek Fuel EX was announced. When I reached out to Trek to inquire about testing one they offered to send a frameset for me to build out. On paper given that it had my ideal geometry, loads of adjustments (including leverage rate!), internal storage and the options of air or coil and mullet or straight 29″, this was the ultimate Swiss army

The downtube storage compartment is on the new bike, and while it seems like Trek has put all the things onto the latest Fuel EX, there's one that they didn't: Knock Block.
Wide range of effective geometry adjustments
Just as much fun on smooth trails as it is on scary trails
Great climber, efficient pedaling
One-piece handlebar might be too stiff for some riders
Paint chips easily
All-new for 2023, the Trek Fuel EX is no doubt the burliest yet. How does it compare to the competition? Read on for our Trek Fuel EX review.
Sturdy, flex-free chassis
Superb geometry with adjustable head angle
Efficient & comfortable climbing performance
Coil shock, big fork & mullet compatibility
Mechanic-friendly frame furnishings
Frame is on the heavy side
Rear shock tune lacks small-bump suppleness
Rattly rear thru-axle lever
New geometry, more travel, and even better suspension improves Trek's mid-weight trail bike.

Does the benchmark trail bike retain its reputation as a solid choice?
Solid feel to the frame
Doesn’t feel as sprightly on climbs as some
Tyres give up corner traction too easily in loose or muddy conditions
Trek's top-tier Fuel EX 9.9 XX1 AXS delights on the climbs and tackles downhill terrain with it's slack (and very adjustable) geometry.

With countless geometry settings and many sizes to choose from, the new 2023 Trek Fuel EX trail bike is supposed to be more versatile and customisable than ever.

Trek’s alloy Fuel EX trail mountain bike lacks the latest features but is the overall package still a winner?
