Flow’s First Bite – Trek Fuel EX 8 29

The not-so-minor details


Trek Fuel EX 8 29


Trek Bicycles Australia




Great improvements to frame geometry.
Wide gear range.
Superb finish.


Needs tubeless conversion.

Trek’s incredibly popular Fuel EX range comes in both 29″ and 27.5″ flavours, and for 2016 the 29er goes under the knife to receive a very trendy facelift, scoring the updates we hoped and wished for. Tighter, zipper and adjustable whilst retaining that super-supple suspension we have grown to expect, the new Fuel EX 29 looks dialled.

Seven versions of the Fuel EX are on offer from Trek Australia, the large range priced between $3099 and $5999. A real testament to how well this type of bike caters to just about any type of mountain biker, the amount of travel, relaxed character and reliable components make it a real winner.

We snagged a Fuel EX 29 8 for a full review, until then here are our first impressions of this entry-level aluminium dually from the big T.

Dual suspension 29ers have come a long way, and are now better than ever across the board. We’re even at the point where we’re seeing die hard ‘small wheel’ riders finally appreciate the benefits of the larger wheels but without moaning that that can’t ride the bike exactly how they would like to.

29″ wheels are always going to be better at handling certain elements of off road riding than smaller 26″ and 27.5″ wheels, the rule that bigger is better just can’t be argued with in terms of rolling momentum or stability. Though there is a reason the Fuel EX is also available in 27.5″ wheels, it comes down to how you want to ride, where you ride and your personal preferences.

We’ve currently got two 27.5″ Treks on long term test – the Fuel EX 9.8 275 and the Remedy 9.8 27.5. Click the links to read our thoughts on those two sweet rides.

In the case of this bike the design team at Trek have been able to take advantage of the new Boost hub width standards to free up space and in return bring the rear end closer to the bikes centre, shortening the chainstays from 452mm to a snappy 437mm. We’ll get into more on how and why Boost is a good thing in our review. Yes it’s another standard that was pioneered by Trek, but there’s more to it than just more standards.

With 120mm of travel front and back, the Fuel EX is a semi-short travel dually that sits in between the bigger Remedy 29 and the amazing new cross country weapon, the Top Fuel. See more of the Top Fuel here.

When we reviewed the 2014 and 2015 Trek Fuel EX 29 the main gripe for us was the length, it got in the way of being the ideal go-anywhere bike, holding us back when corners got tight. We often wished for different geometry when we wanted to throw it around and play. So naturally we’re pumped to see that on paper it looks like that’s sorted for 2016, we can’t wait to see how it goes on the trails. To read our earlier reviews of the Fuel, read here: 2014 Trek Fuel EX 9.8 29 and 2015 Trek Fuel EX 9.9 29.

With a good dose of Bontrager, FOX and Shimano the Fuel is well dressed for the dollars. In our experience the parts fitted to this bike will be up to the task, but we’ll deliver our verdict in the review.

Trek are all about a good range of gears, most of their Shimano drivetrain bikes are specced with a double chainring. With a 2×10 drivetrain, the low range is especially very useable and you won’t be running out of gears at either end.

FOX take care of the suspension with a Float 32 fork up front using the new FIT 4 damper that has brought FOX back into the game in a big way. Plus the addition of the EVOL large air volume air can this is surely going to be most excellent! The Fuel range was already a supple and smooth ride, with the new FOX parts it’s going to be off the charts! 

The rear shock uses Trek’s proprietary suspension damping system called the Re:aktiv damper designed in conjunction with FOX. It’s all about delivering better pedalling/climbing efficiency with a more seamless transition to bump absorption than other systems have been able to achieve. Read more about that here: RE:aktiv Shock Technology.

Bontrager handle the rest of the parts, which is good news to us. While the wheels may be a little weighty, we already love the tyres, saddle and cockpit.

The Fuel EX 8 29 looks pretty good to us! With a tubeless conversion it’d be perfect on our rocky trails, so we’ll be taping up the rims and sourcing some tubeless valves to make that happen, then we’ll be good to go. Let the testing begin, stay tuned for the full review soon.
