TREK Fuel EX 8 27.5 Plus 2019
|Options||Sizes: 15.5, 17.5, 18.5, 19.5, 21.5, 23"; Colour: Matte Dnister Black - USUALLY AVAILABLE WITHIN 3-10 DAYS|
Fuel EX 8 Plus is a versatile full-suspension trail bike with chunky, plus-sized tyres for unrelenting traction. It's the perfect balance of value and performance, with a trail-tough Alpha Platinum Aluminium frame, 140mm front and 130mm rear suspension and a wide-range SRAM GX Eagle 1x12 drivetrain.
- 130mm travel rear suspension within a 29" or 27.5+ compatible frame
- Straight Shot stiffness, Knock Block frame defence
- Doubly stiff: the wider Boost148 rear and Boost110 front hub spacing creates stronger, less flexy wheels and allows for wider tyres, shorter chainstays and more chainring options
- RE:aktiv: developed in conjunction with Penske Racing Shocks, RE:aktiv's regressive damping helps deliver what ever rider wants: suspension that's stiff and efficient to keep you fast in the straights and planted in the corners, but supple and instantaneously responsive when you hit an obstacle.
- Smooth, controlled braking: Patented ABP (Active Braking Pivot) keeps your suspension from stiffening up when you're on the brakes, giving you confident, steady control.
- Superb high-speed control: The greater your control, the harder you can roll. Mino Link adjustable geometry is tuned for better high-speed control.
Upgrades from Fuel EX 5 Plus:
- Fox Rhythm 34 Float fork
- Fox Performance Float shock with Trek's RE:aktiv technology
- Bontrager sealed bearing hubs
- SRAM GX Eagle 1x12 drivetrain
- Bontrager Line dropper seatpost
Better frames for a better ride:
We know why you ride. It's not to ponder how light your frame is, or contemplate the stiffness of your rocker link. You just want the performance those things give you. It's why Trek pack their frames with performance-enhancing technology, and summarise it all with simple words like EVO and Full Floater. Simple words, complex solutions, a better ride.
Other suspension systems firm up under braking. Active Braking Pivot (ABP) allows your suspension to remain active, whether you're pedalling, coasting or braking.
This means your bike performs as it was intended, all the time.
Most suspension systems attach the shock to a moving linkage at the top, and a fixed frame mount on the bottom.
Full Floater attaches the shock to two moving linkage points that give the shock increased ability to respond to bumps across a wide variety of terrain.
It feels like more travel, but it's not. It's smarter travel.
Wider dropouts at the front and rear give greater stiffness. Boost148 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
Straight Shot with Knock Block:
Straight Shot is a straight downtube that makes the frame stiffer so your Fuel EX won't flinch on rough descents. Knock Block is the defence required for this radical frame design, to prevent accidental damage if the forks spin right round.
Mino Link Adjustable Geometry:
Fine-tune the head tube angle by 1/2 degree and bottom brackt height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive technology.
The EVO Link is Trek's evolution of the rocker link from the plate-and-bolt style used on most suspension bikes today to a one-piece rocker link. This lighter link provides a stronger connection at the system's most crucial connection point between the front and rear triangles, creating a stiffer frame for greater control with minimal weight.
RE:aktiv brings Formula 1 technology to mountain bike suspension. A Trek exclusive. Trek wanted a shock that could do it all: truly efficient control combined with the ability to respond instantaneously to big impacts. Every so-called solution involved a trade-off, compromising efficiency or responsiveness, or both. To exploit the industry's best air shock - DRCV - required some serious damping expertise. Damping moderates how the suspension behaves, controlling travel speed and resistance. Inspiration was sought from Penske, who create custom suspension systems for motor racing teams. No off-the-shelf solutions, no mass production, no compromise.
Penske had already devised an innovative solution for Formula One that allows a valve to instantly open up to absorb an abrupt bump then instantly close up for a stiff, efficient response, with an undetectable transition in between. This is regressive damping. Three years of development by Trek in collaboration with Penske and Fox has refined the technology for mountain bikes.
RE:aktiv means the shock acceleration caused by an abrupt hit makes rocks and roots almost disappear, and the instant closure of the valve when the bumps stop/shock acceleration slows results in regaining immediate control. Thus Fuel EX rides like an XC bike when you want it to, like a downhill bike when you need it to, and you'll never feel the switch.
Alpha Platinum Aluminium:
Trek's best high-performance lightweight aluminium alloy is continuously cold extruded and butted at multiple points for ultimate weight reduction and superior strength. Frames built with Alpha Platinum feature a high degree of hydroforming to create the most complex industrial designs for the lightest weight, and are finished using Trek's smooth-weld finishing process.
Sometimes you need a little extra protection, so Fuel EX 8 Plus gets a light, tough external shield. The Armour polymer shield adds reassurance to riders who know their downtube is bound to take some abuse.
Press-fit bottom bracket:
Press-fit BB is a bottom bracket shell that allows the bearings to press into the frame rather than thread in like standard bottom brackets. This provides a wider stance for the frame's tubing juncture, resulting in a stronger frame. This wider stance also simulates benefits of an OCLV Carbon-only technology, BB95.
Dropper post and internal cable routing:
Fuel EX 8 Plus is equipped with a dropper post which is great for while-you-ride seat-height adjustments. The remote cable is routed directly through the frame for the sleekest setup you've seen.
Control Freak Cable Management:
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lock-out and dropper post lines to be routed through the frame for clean looks and the ultimate custom set-up.
International Standard Chain Guide mounts offer easy chain guide installation and adjustment.
Trek Fuel EX 8 Plus review (long term test, the final verdict), mbr Magazine, Summer 2017:
What attracted you to the Trek Fuel EX 8 Plus?
I was keen to see how the completely redesigned Trek Fuel - a bike I've enjoyed riding in the past - would perform over its predecessor, and also how the Trek's 2.8in tyres would fare against my previous experience with 3.0in rubber on my last longtermer: the Specialized 6Fattie Plus bike. On paper, the Trek looked to address some of my issues with the 6Fattie, specifically in the geometry department.
How did it ride?
Really well. I was consistently impressed with its performance and it's a seriously fun bike to ride. So much so, that I looked forward to every ride on the Trek with genuine excitement. The more progressive geometry rewards on fast, steep and technically demanding trails where it's really stable but the bike is still easy to chuck from corner to corner.
Bontrager's 2.8in tyres deliver good traction, but they do have a narrow window of perfect operating conditions. Let's just say they're not much cop in the mud. Being able to slot in a pair of 29er wheels and decent tyres helped in the slippery winter conditions, and injected even more pace into an already rapid ride.
Did anything break or wear out?
The Trek was a lot more reliable than my old Specialized, which required regular maintenance. The SRAM GX groupset proved to be solidly built and it just got on with the job without any fuss. The KS eThirty Integra dropper post provided good service, but I wish I had ponied up for the more ergonomic Southpaw lever that the company offers as an upgrade.
Would you buy this bike?
It'd be a shame to see the Trek go back, so yes I'd definitely buy it. I am sold on Plus tyres but choice is still a limiting factor, and having ridden the Fuel with 29er wheels, I think I'd probably buy the big-wheel version - such as the EX 7 29 that won last month's bike test. Still, that's not something I was expecting when the bike first arrived, and it's great to be able to choose between wheel/tyre sizes depending on your frame of mind, or trail conditions.
- Updated geometry and the extra travel increase the speed and thrill factor of the Fuel EX
- Great suspension and easy to fettle to perfection
- SRAM GX once again puts in a splendid performance, so wy pay more?
- 2.8in Chupacabra tyres only really work in dry conditions
- Shorter stem and wider bar would be a nice addition
- It's a little on the heavy side, not that you can tell from the ride quality
