Alpha NEXT Platinum Aluminium Frame
The Trek Fuel EX 8 features an Alpha NEXT Platinum aluminium frame designed to balance strength, stiffness and weight. Its modern trail geometry provides stability on technical descents while maintaining responsive handling for tighter trails and challenging climbs.
The frame offers 145mm of rear suspension travel, with the option to adapt the platform for different riding styles using interchangeable components. Guided internal cable routing keeps cables protected, while a threaded BSA bottom bracket makes maintenance straightforward.
Fox Rhythm 36 Suspension Fork
The Fox Rhythm 36 fork provides 150mm of travel to absorb rocks, roots and larger trail impacts. Its Float EVOL air spring allows riders to adjust suspension pressure to suit their weight, while the GRIP damper controls compression and rebound for consistent performance across varied terrain.
The 36mm chassis provides additional stiffness for accurate steering, particularly when riding rough trails or braking hard on descents.
Fox Float X Rear Shock
The Fox Float X rear shock controls the Fuel EX 8's 145mm of rear suspension travel. Designed for demanding trail riding, it provides a balance of small-bump sensitivity and support through larger impacts.
The air spring allows riders to adjust suspension pressure for their weight and riding preferences, helping maintain traction and control across changing terrain.
Adjustable Suspension Progression
The Fuel EX 8 features an adjustable leverage rate, allowing riders to change how the rear suspension behaves deeper into its travel.
Flipping the chip in the lower shock mount increases progression, providing greater resistance to bottoming out on larger impacts. The alternative setting offers a more linear suspension feel, giving riders the option to tailor the bike to their riding style and preferred terrain.
Active Braking Pivot Suspension
Trek's Active Braking Pivot (ABP) suspension design allows braking forces and suspension movement to be managed more independently.
This helps the rear suspension remain active when braking over rough ground, improving traction and maintaining control on technical descents.
SRAM Eagle 70 T-Type Drivetrain
The SRAM Eagle 70 T-Type 1x12-speed drivetrain provides a wide gear range for climbing and descending. Its 30T chainset and 10-52T cassette offer low gearing for steep climbs while maintaining suitable ratios for faster sections of trail.
The T-Type transmission mounts directly to the frame rather than using a conventional derailleur hanger. This provides a robust connection and helps deliver consistent shifting, including when pedalling under load.
SRAM DB8 Hydraulic Disc Brakes
SRAM DB8 four-piston hydraulic disc brakes provide strong, controlled stopping power for demanding trail riding.
Their four-piston design offers consistent braking performance on steep descents and technical terrain, helping riders manage speed with confidence.
Bontrager Line TLR 30 Wheels
The Bontrager Line TLR 30 wheelset features tubeless-ready aluminium rims designed for trail riding. Their 30mm internal width provides a suitable platform for wider mountain bike tyres, helping support the tyre profile when cornering.
Boost110 front and Boost148 rear hub spacing contribute to wheel stiffness, while the Rapid Drive 108 rear hub provides quick engagement when accelerating out of corners or negotiating technical climbs.
Bontrager Brevard Pro XR Tyres
The Trek Fuel EX 8 comes equipped with Bontrager Brevard Pro XR 29x2.5-inch tyres front and rear.
Their dual-compound rubber and trail-focused tread provide traction on loose surfaces and technical terrain, while the wider profile offers additional grip and cushioning over rocks and roots.
The tubeless-ready construction also allows riders to convert to a tubeless setup with compatible components and sealant, helping reduce the risk of pinch punctures.
Bontrager Line Dropper Post
The Bontrager Line Dropper seatpost provides 200mm of travel, allowing riders to lower their saddle for technical descents and raise it again for efficient pedalling.
The frame has been designed to accommodate longer dropper posts, giving riders additional freedom of movement when descending and negotiating challenging trail features.
In-Frame Storage and Accessory Mounts
Integrated frame storage provides a convenient place to carry small ride essentials without needing a backpack.
Additional top tube accessory mounts offer further carrying options, making the Fuel EX 8 practical for longer rides where tools, spares and nutrition may be needed.
Adaptable Fuel Platform
The latest Trek Fuel platform is designed around versatility, with three configurations offering different suspension travel and riding characteristics.
The Fuel EX focuses on all-round trail riding with 145mm rear and 150mm front travel. The MX configuration prioritises a more playful riding feel, while the LX offers additional suspension travel for rougher, more demanding terrain.
Interchangeable rocker links and lower shock mounts allow the frame platform to be adapted, although converting between configurations requires the appropriate compatible components.
The frame also uses a standard zero-stack headset arrangement, providing options for compatible aftermarket headsets, including angle-adjusting designs.
Versatile Trail Performance
The Trek Fuel EX 8 is designed for riders who want one mountain bike capable of handling a wide variety of trails. Its combination of adjustable suspension, modern geometry and dependable components makes it equally suited to technical climbs, flowing singletrack and challenging descents.
With 145mm rear travel, a 150mm Fox fork and 29-inch wheels, it offers a balanced approach to trail riding, providing enough suspension for rough terrain without sacrificing the efficiency needed for longer days in the saddle.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
