Trek has announced an update to its very popular XC bike, the Top Fuel, that takes it further into the realms of other fast trail/XC race/marathon bikes rather than it being a dedicated World Cup machine.
The new Trek Top Fuel is longer and slacker, with longer travel and room for bigger tyres. There’s even room for longer dropper posts and a flip/flop stem that instantly gives a more trail-ready riding position. All exciting stuff, so let’s dig deeper:
Whereas previous Top Fuel models featured a 100mm fork and 100mm of rear travel, the new Top Fuel models have a longer 120mm fork and 115mm of rear travel. Reach has gone up by 5mm or so (a M/L is 461mm in ‘high’ and angles have been tweaked. The bike still features the Mino flip-chip adjustment for a lower/slacker ride or a higher/steeper setup, but angles overall have changed a fair amount, with the new slack/steep seat and head angles respectively now being: 75°/67.5° in ‘Low’ and 75.5°/68° in ‘High’.
As you might expect, the frame is 29in only and comes with a Twistloc dual remote lockout that locks front and rear shocks for sprinting and endless climbs. Each of the models in the new Top Fuel lineup features a wider handlebar and shorter stem and a size-specific dropper post. The smallest size (with a 39.4cm seat tube) gets a 100mm dropper, but the Medium and M/L sizes get a 150mm dropper, with the Large and XL sizes getting a full-on 170mm dropper post.
The bike will come in either (Trek’s Alpha) aluminium, or in OCLV carbon and in four complete build options or as a frame-only.
The complete Top Fuel 9.9, Top Fuel 9.8, and Top Fuel 9.7 and the carbon frameset feature full OCLV Mountain Carbon mainframes and rear triangles.
The geometry chart is below:
And while the bike looks pretty mean and purposeful with its -13° stem, it can also be flipped up when you’re not wearing your race Lycra. This raises the bars by 47mm or so to give a much more upright and playful position. With the travel now at 120/115mm front and rear, it’s trying to show that it can also be a fun trail machine too. You can even fit 2.4in tyres…
