Comparing drivetrain

Comparing drivetrain

Before, the Fuel Ex also had Shimano, but the latest model has SRAM GX Eagle for its drivetrain. It is best to compare the two, as there lies a significant difference between them.

SRAM GX Eagle is made of carbon and is perfect for trail mountain bikes.

It allows for better suspension, lighter but as durable as aluminum, which you have with Shimano, the drivetrain component of Trek Top Fuel.

However, older versions of Fuel Ex previously had Shimano XT, almost the same, though not as high-end, as that of Shimano XTR in Top Fuel.

The Trek Top Fuel is for cross-country riding. A traditional gear made of aluminum fits perfectly well. This mountain bike does not have to deal much with so many uneven terrains and super rugged trails.

On the other hand, Fuel Ex, as a trail bike, has to deal precisely with those things.

The need for toughness in unforgiving terrain and an unexpected trail must be why Fuel EX now has SRAM GX Eagle.

SRAM is one of the best, talking about quality bike parts for trail riding. Made of carbon, it is durable but lighter than aluminum.

It can make quality shifts vital when aggressively trail riding without sacrificing poise, balance, and control. Perfect for the top trail bike, which is the Fuel Ex.

Being a cross-country mountain bike, the Trek Top Fuel does not need what SRAM GX Eagle offers. Hence, the traditional gearing provided by Shimano.

Comparing Suspension

Trek Top Fuel and Trek Fuel Ex also have the same suspension technology: the Monolink, Active Breaking Pivot (ABP).

And this is the suspension you have for both Trek bikes.

But Trek Top Fuel has a shorter suspension travel of 120mm. Fuel Ex, meanwhile, has a 140mm suspension on the front and 130mm rear travel.

Fuel EX suspension technology is perfect for a trail bike. Ideal for any trail. On the other hand, the suspension of Trek Top Fuel is an ideal fit for cross-country rides.

Trek Top Fuel can take some trail, but this mountain bike is mainly on a single track. Trek Top Fuel need not cover a wide variety of terrain and has to deal with fewer obstacles.

As a trail bike, Fuel Ex does cover a wide variety of terrain. A rugged trail is easy picking for this mountain bike.
