Technical specifications

Who is it for?

For the mountain biker who rides dry, dusty, rough trails and wants, above all, a bike that holds its line and brakes hard. It also suits anyone discovering e-MTBs in demanding terrain like the foothills of the Caroux.

The LVR workshop view

OCLV carbon, Trek's signature. OCLV sums up a process Trek has mastered for more than thirty years: compacting the fibre layers under pressure and at high temperature to drive out the air. For the Fuel+, the brand uses its Mountain version, designed to shrug off rocks and crashes rather than to save the last gram. This carbon frame carries a Trek lifetime warranty, with the removable battery housed in its down tube.

Put simply: the 9.7 gives you the Fuel+ EX carbon frame while keeping sensible components: Fox Rhythm up front, Float X at the rear, Eagle 70 and DB 8 brakes. It weighs 20.68 kg in M, a kilo less than the aluminium Fuel+ EX 8.

The Assegai is a tyre with tall, widely spaced knobs, known for biting into loose ground and rolling stones. Paired with a Bontrager Brevard Pro XR, it gives the 9.7 reassuring grip in the garrigue around Béziers, where summer dust makes corners slippery. The right tubeless pressure gets the best out of it.

On an electric bike, the extra weight and higher average speed put more strain on the brakes: the two 200 mm rotors spread the heat better on long descents. The 800 mm handlebar offers generous leverage to position the bike; we can cut it down in the workshop if your shoulders are narrower.

Which Fuel+ should you choose?

Our take: with equivalent braking, the 9.7 weighs 20.68 kg against 21.68 kg for the aluminium Fuel+ EX 8. The 9.8 Eagle 90 (20.38 kg in M) moves up to Maven Bronze brakes and Maxxis Minion tyres front and rear.
