Trek Fuel EX 5 Vs 7 Mountain Bike ?

Some people see them as two Trek trail bike generations apart. Others see them as two similar models with just an identity separation. I’m talking about Trek Fuel EX 5 vs 7, and the obvious question is, what’s the difference?

Trek Fuel EX 5 weighs slightly more than Trek Fuel EX 7 and features a 1×12 Shimano Deore M6100 drivetrain, which is slightly low-end than Fuel EX 7’s 1×12 SRAM NX Eagle. Application-wise, EX 5 is best for casual trail riding and occasional enduro and XC racing, while EX 7 is an all-around choice.

Other than differentiating these two Trek Fuel EX bikes according to their weight, drivetrain, and suitability, you can tell their difference from their frame colors and prices, as shared in the table below:

Given that Trek Fuel EX 5 and EX 7 belong to the same family line (the Trek Fuel EX line), you should expect them to have more in common than differences. So, we’ll also highlight these similarities once we exhaustively differentiate them.

But first, let’s jump into the bike’s overview.

Trek Fuel EX 5 Review

The Trek Fuel EX family is known for its balanced trail geometry and trail-ready suspension setup, and that’s what you get from Fuel EX 5.

Trek Fuel EX 5 is one versatile mountain bike with 140mm suspension upfront and 130 mm in its rear. As a result, this full-suspension trail beast can take on some of the most challenging trails.

It comes with an innovative frame that employs Mono Link and Active Braking Point (ABP) suspension innovations to offer you more bike control and exceptional comfort.

Trek Fuel EX 5 has high-end specs that make it a high-performance trail bike. Though this bike is not an enduro monster or a cross-country speed beast for serious riders, you can engage it in cross-country and enduro races and still beat most guys with actual enduro and XC bikes.

The only competition you cannot ride is the elite level, as competitors are likely to grace the event with bikes with higher-end specs and slightly lighter ones.

Overall, Fuel EX 5 weighs 34.62 pounds without its tubes which may be slightly heavier than most mid-range and high-end MTBs, including its siblings Trek Fuel EX 7.

However, the extra pounds are not a big issue for casual riding and mid-level enduro and XC courses. Primarily its impressive performance is due to its 12-speed Shimano Deore M6100, which is the newest entry into the Shimano Deore groupset family but is quite reliable and efficient.

I also cannot forget to mention its impressive suspension and suspension technologies, robust all-terrain tubeless-ready wheels, and ever-responsive all-season Shimano hydraulic disc brakes. So, build-wise and performance-wise, Fuel EX 5 is a decent purchase.

Trek Fuel EX 7 Review

Judging by looks (apart from the frame colors), there’s nothing to separate Trek Fuel EX 7 from Fuel EX 5. But if you scrutinize the specs, one thing stands out: the drivetrain.

Instead of going for Shimano Deore M6100, Trek settles on SRAM NX Eagle here. The difference is that NX Eagles Shimano equivalent is Shimano SLX and not Shimano Deore.

SLX ranks just above Deore on the Shimano groupset hierarchy, making SRAM NX Eagle slightly more high-end than Deore M6100.

You can count on Fuel EX 7s 1×12 SRAM NX Eagle drivetrain for fast and efficient shifting, and like every other SRAM NX Eagle, it’s robustly built to last longer.

Trek Fuel EX 7 weighs 31.93 pounds, making it 2.69 pounds lighter than Fuel EX 5 even though they share the same frame material, sizing formula, and design.

But like Fuel EX 5, EX 7 employs both Mono Link and ABP (Active Braking Point) suspension technologies which promise unmatched control, confidence, and comfort when taking on the trails. 

Overall, Trek Fuel EX 7 is an all-rounder full-suspension trail beast. You can not only use it for casual biking and occasional enduro and XC courses but also use it for touring, commuting, mountain biking, and just about anything, you may want it to be.

This trial bike can be your day-to-day adventure bike or your competition choice, depending on what other riders bring to the event. Unless they are elite athletes and the competition is an elite one, they are unlikely to bring a higher-end bike than this.

You can count on its fast-shift Shimano NX Eagle drivetrain, innovative suspension, and lightweight frames for top performance.

Trek Fuel EX 5 vs 7 Side-by-Side Comparison

Generally, here’s how Trek Fuel EX 5 and EX 7 compare:

1. Drivetrain 

These two bikes are primarily distinguishable by their drivetrains. Trek Fuel EX 5 comes with a 1×12 Shimano Deore M6100 drivetrain which comprises of:

  • 12-speed Shimano Deore M6100 shifters
  • Shimano Deore M6100 long cage rear derailleurs
  • 12-speed Shimano Deore M60 
  • 12-speed Shimano Deore M6100 chain

In contrast, Trek Fuel EX 7 features a 1×12 SRAM NX Eagle drivetrain which comprises of:

  • 12-speed SRAM PG-1230 NX Eagle shifters
  • NX Eagle rear derailleurs
  • 12-speed SRAM PG-1230 NX Eagle 11-50 T
  • 12-speed NX Eagle Chain

Clearly, the two drivetrains are different (even though they are both 12- speed), which brings about a difference in performance.

Quality-wise, SRAM NX Eagle is a slightly higher grade than Shimano Deore M6100. As a result, it promises a crispier shifting, more reliability, and more strength and generally gives Fuel EX 7 a slight competitive edge over Fuel EX 5.

Nonetheless, you may fail to note the difference if you use either bike for occasional enduro and XC races, casual biking, or trail adventures.

2. Trek Fuel EX 7 Vs EX5 Weight

Trek Fuel EX 5 weighs 34.62 pounds, excluding the tubes, while Fuel EX 7 weighs 31.93 pounds. That makes Fuel EX 7 2.69 pounds lighter than its compatriot, giving it a slight competitive advantage.

Trek Fuel EX 7 is likely to feel slightly more comfortable than Fuel EX 5 when riding fast because of the slightly lower weight.

3. Bike Suitability

Owing to its lower weight and slightly higher-end 1×12 SRAM NX Eagle drivetrain, Trek Fuel EX 7 is an excellent all-around mountain bike.

You can use it for entry-level and mid-level competitions, including cross country and enduro courses. You can also use it for trail adventures, off-road commuting, local cruising, fitness cycling, running errands, etcetera.

Trek Fuel EX 5 is also another versatile choice. But since it has a slightly lower-end drivetrain, it’s only best for occasional enduro and cross country races and casual riding.

If you want something more competitive, you may have to opt for Fuel EX 7 or any other higher-end choice.
