Trek's Top Fuel has traditionally sat at the pointy end of it's cross country full-suspension range, but with a complete makeover for 2020, it's now pitched at the light'n'fast trail riding crowd, with more travel, longer geometry and more aggressive angles.

The new bike is being pitched as being a much more versatile trail machine than the race-focussed bike of old. To that end, travel has been boosted from 100mm all round to 120mm up front and 115mm at the rear, though retaining the 29" wheels.

As you'd expect, geometry has also been tweaked in a similar direction with a large sized frame now getting a not-insubstantial 475mm reach. It's possible to tweak bottom bracket height and head angle thanks to a flip-chip on the shock rocker, with head angle at 67.5º in the slacker setting, while the seat angle sits at 75º. Flipping the chip then gets you a 68º head angle and steeper 75.5º seat angle.

Trek has also punted the main pivot on their ABP concentric rear pivot system a bit further forwards, which they saw has improved pedalling performance. You can now also squeeze in up to a 2.4" tyre in the back end too.

All the bikes now come with a dropper post as standard, with small bikes getting a 100mm item, medium and above getting 150mm and higher end large and extra large machines getting 170mm. As this potential for radness is paired to shorter stems and wider bars, natch.

The lineup consists of both carbon and aluminium frames, with the range starting at £2,600 for an aluminium SRAM NX bike, while those with deep pockets can opt for the range-topping, all carbon £8,700 Top Fuel 9.9 XX1 AXS.
