2020 Trek Top Fuel: What you need to know

2020 Trek Top Fuel

You may know that I am a big fan of Nukeproof mountain bikes, but I am also a big fan of Trek Mountain bikes. After I rode the Trek Remedy 8 and the Fuel EX, I realised how good Trek Bikes are. The 2020 Trek Top Fuel promises to be pretty fantastic, with its updates.

If you are not in the know The Trek Top Fuel is a light weight mountain bike designed primarily for XC races. But, the 2020 Trek Top Fuel ticks a few more boxes than its predecessor. It is now going to be more versatile, making it suitable for cross country racing and trail riding.

The 2020 Trek Top Fuel's Improvements

Suspension

The 2019 Trek Top Fuel has 100mm of travel front and back. But the 2020 version has 120mm on the front and 115mm at the back. These changes will make riding the 2020 Top Fuel over technical terrain a little easier.

The mounting of the rear shock has also changed for 2020. To improve cable routing and frame stiffness, it now has a fixed lower shock mount, while the mino link  has been moved in front of the rocker link and the upper shock mounting bolt.

Geometry

The geometry is described as more balanced compared to the current version, with a steeper seat tube angle, slacker head tube angle, and longer reach. But the Mino link allows you to adjust the geometry slightly, by flipping it. You can make the geometry slacker or steeper, depending on your preference.

These changes make the 2020 Trek Top fuel more friendly for trail riding, without losing the cross-country performance that the Top Fuel is known for.

Frame

The frame has Trek’s Control Freak internal cable routing system. This makes everything nice and tidy, but it also stops rattling. The downtube is said to be stiffer and lighter. Trek have fitted the 2020 Top Fuel with their Knock Block steering system. This stops the fork coming in to contact with the frame in the event of a crash.

The 2020 Trek Top Fuel’s frame has a 1x drive train. This allows a maximum of a 34t chainring. It will accommodate a maximum brake disc size of 180mm. In the spirit of making this bike better for trail riding, the frame allows for a larger rear tyre. There is enough space for a 29 x 2.4″, to give you loads of grip.

If you decide to buy a 2020 Trek Top Fuel, you will get a dropper post and a directional 13 degree stem. This can be flipped up to make the bike more focused for trail riding or down for cross country. This stem allows to to adjust the position of your handlebars by 47mm too.

All versions of the 2020 Top Fuel will have a carbon frame, apart from the Fuel 8, which is aluminium.

 Pricing starts at $3,299.99 for the Top Fuel 8 NX up to $9,999.99 for the top end Top fuel 9.9 XX1 AXS. Two framesets will also be available with the alloy and carbon option. Standard bikes should be available now, with Project One carbon options available in Late July.

Models

Trek Top Fuel 9.9 XX1 AXS

The 9.9 XX1 AXS is the range topping version of the 2020 Trek Top Fuel. It features wireless components, such as the SRAM XX1 Eagle AXS drivetrain and RockShox Reverb AXS dropper. The suspension is pretty luxury too, as it is from the high end of the RockShox range.

If you are in to carbon fibre, you will love this. The frame, wheels, handlebars and shifters are all made of it, making this bike as light as possible. It is designed to take on most types of trail, but it will excel on long distance cross country races.

Trek Top Fuel 9.9

This version of the 2020 Trek Top Fuel has an OCLV Mountain Carbon frame. The specification is different from the 9.9 XX1 AXS above, but it is still impressive. It has a Fox Factory Float rear shock and a very nice Fox Factory 34 Step-Cast fork at the front. The SRAM XX1 Eagle drivetrain will keep you pedalling up the steepest of hills, while the SRAM Level Ultimate brakes will stop you from rolling down the other side.

Trek Top Fuel 9.8

The 2020 Trek Fuel 9.8 is specced to be in the middle of the range. It’s frame is also built out of the OCLV Mountain Carbon fibre. Just because it is in the middle of the range it doesn’t mean it is not a high end bike. For example, its 120 mm Fox Performance 34 Step-Cast fork does a great job of absorbing bumps. The SRAM GX Eagle drivetrain and carbon wheels and bars are luxury items too.

Trek Top Fuel 9.7

This version is probably the one most people will buy, due to its price positioning. Although, you will see from the specs below, it is still a well specced bike. TheTrek Top Fuel 9.7 still has features such as the TwistLoc system. This locks out front and rear shocks at the same time. Which is perfect for efficient pedalling. Speaking of pedalling, you get the  12 speed SRAM Eagle drive train, which I am a massive fan of.

What are your thoughts?

If you want a very capable cross country bike that will feel at home on single track, the 2020 Trek Top Fuel is a great option. As you can see there is quite a range to suit most budgets. Have you had any experiences with these bikes? I would love to know your thoughts. Also, if you have any questions, let me know in the comments section below.

    Thanks for this post. I’m not much a cyclist, but my brother is. He’s always riding all over the place. He even takes a bike with him when he travels out of country for work. I’ve always wanted to get him a really good mountain bike to pay him back for how he’s helped me out through the years.

    i appreciate that you highlight that this line of bike can be used for both cross-country and trail riding. Since my brother does both, this would be a better option because it’s designed for both. I can get him the one bike that he can use for both. To me, it would be worth the investment to get a bike that offers such versatility. 

    Plus, an improvement in the suspension has to be a major benefit. I can only imagine the wear and tear on the body from a suspension system not fitted to the terrain. 

    Again, thanks for the information. This is definitely a line of bikes I want to investigate further.

    Hi Tom

    Trek Top Fuels is very interesting. I’m an old man and have to admit that this whole niche is very new to me. But, I have a 6-year-old grandson who is highly interested in dirt bikes and mountain bikes. You have provided some very powerful information here. I like the way you give us substantive content as well as procedural content. You give the step-by-step process of Trek Top Fuel’s bikes in a clear and cogent fashion. Your graphics of the bikes, including the detailed diagrams, of geometry, frames, and models were also visually appealing and helped with understanding the bikes. I was surprised though by the prices. It never dawned on me that these could cost more than a lot of cars. 

    Thanks to you I now know what to look for when I take my grandson shopping. He’s going to be very impressed by my newfound knowledge of these bikes. 

    Thank you for this great information. 

    God bless you!
