TREK FUEL EX

Fuel EX Technology
The all-new Fuel EX is a dramatic improvement over any mountain bike Trek (some would say any company) has ever offered. This improvement is due to the groundbreaking new technologies of ABP™, Full Floater™ and EVO Link™ – the combination of these technologies is a suspension platform known as R1i.™
One ride is all it takes to know that the 2008 Fuel EX is the ultimate trail bike.

 

ABP™ (Active Braking Pivot) - Why Skid?

Conventional designs place the rear suspension pivot either below or above the axle. Trek’s new Active Braking Pivot (ABP) is a patent pending technology that puts the rear suspension pivot concentric to the rear wheel axle. This new pivot location results in a bike with the most active suspension under braking.

Reduces Braking Forces on Suspension Braking forces cause most suspension systems to stiffen (commonly known as brake jack). When suspension stiffens, it’s not able to fully track bumps, resulting in wheel hop, increased skidding and decreased control.
Trek’s new Active Braking Pivot (ABP) places the rear pivot concentric to the rear axle, which reduces the effect of braking on the suspension system. In fact, ABP creates the most active suspension under braking. Since ABP keeps suspension active, your shock doesn’t ‘pack up’ under high frequency bumps, allowing your wheel to track every bump. The result – reduced skidding, more control, and better, more effective braking.

Perfect Suspension Balance Front-to-Rear Since ABP allows the rear suspension to work efficiently in both braking and non-braking situations, the front and rear shocks can work together all the time. This creates a perfect balance of suspension front-to-rear and adds up to better handling and more control in all situations.

You’ll Never Think About Full Suspension The Same

1) Full Floater™ - Smarter Travel
Trek’s highly successful R1 suspension system allowed our suspension designers to dial in the rear suspension’s leverage ratio (the amount a shock is compressed as a function of wheel travel) while maintaining a rigid, durable frame and swingarm structure.
The R1i system takes a huge step forward with the all-new Full Floater rear shock mounting technology.

2) Shock Floats on Two Moving Linkages
Fixed mount suspension designs attach the shock to one top moving link while the bottom mount is fixed to the frame. Full Floater technology connects the rear shock mounts to two moving linkages – the EVO Link on the top, and the extension of the swingarm at the bottom. The trajectory of these two attachment points adds a degree of freedom to the shock mounting system and creates a more complex leverage ratio, one that is optimized for use with an air shock. The new system performs in a way that was not possible with the previous system, providing a system that is active over the small stuff with good control of the mid stroke, and precise end-stroke compression.

3) EVO Link™
No matter how stiff a full suspension frame’s front or rear triangle might be, the complete bike can only be as stiff as the connection that joins the two. That’s why the all-new Fuel EX no longer uses a three-piece Rocker Link. Instead, the EVO Link is a one-piece design that is lighter, stiffer, and more compact.

R1i™ - Suspension Intelligence
R1i takes R1 a huge step forward with the all-new Active Braking Pivot (ABP), Full Floater rear shock mounting technology and EVO Link.
The new R1i system performs in a way that was not possible with the previous system. It’s stiffer than the previous system and offers more control in every trail condition.
