Arguably one of the all-time most popular bike models of any MTB on the planet, the ‘Fuel Ex’ has been at the peak of Trek’s MTB line-up for as long as anyone can remember and it has had no fewer than six major design overhauls during that time. Late last year Trek unveiled their newest reinvention of the ‘do it all trail bike’ which rolls out of the store boasting a ton of rider customisation features, including a choice of [...]

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
