2020 Specialized Stumpjumper Evo Pro Overview

The 2020 Specialized Stumpjumper Evo Pro is a £6,800 bike, that comes with either 27.5″ or 29″ wheels, just like the alloy versions. It has 150mm of rear travel from the FOX DHX2 Performance Elite shock. You also get 150mm at the front from the FOX FLOAT 36 Performance Elite. There is a 29er with 140mm of travel on the rear.

This bike is not a traditional trail bike. It is a high end trail bike that is suitable for technical downhill trails with rocks, roots, drops and jumps. The 2020 Specialized Stumpjumper Evo Pro is for riders that like to ride aggressively on these types of trails, especially those that like to ride downhill. So it is a downhill bike that can be pedalled up hill.

It comes in two sizes S2 and S3, this is so you can choose the size to suit your style of riding. The best way to think of these two sizes is ‘long’ and ‘longer’. If you are like me and vertically challenged, you would be better to go for the S2 size and larger rides should go for the S3. If you are in between, you will have the luxury of choosing, depending on your personal preference and how you like a bike to ride.

Design Characteristics

The most notable characteristic of this bike’s frame is the design of the new sidearm. The front end and the trailing end are linked together at three points. The new sidearm design makes sure these points are super stiff.  It also reduces the weight of the rear end by 100g. But, the most important thing, is the stiffness it brings to the frame.  Stiff frames are more responsive, making the bike more agile.

The way mountain bike suspension performs depends on a few things the wheel size as well as the size of the rider. This is where Specialized’s Rx tune comes in. This puts the bike in the middle of the adjustment spectrum. This means you can a lot of room to tweak the bike to get it exactly how you want it. The Rx tune is specific for each of the 27.5″ and 29″ wheeled versions. This is so the suspension moves in a perfectly linear motion, making it the most efficient as it can be. 

Specialized have reintroduced threaded bottom brackets, this makes maintenance much easier than the push-fit alternative. The amount you can tune your Evo has been well thought out. They have given you room to fit a 3″ wide tyre, for extra grip. Specialized have thoughtfully given you the ability to fit whatever aftermarket rear shock you want. Customisation is furthered with a Flip Chip. This allows you to change the ride height of the bike. When you switch it from high to low for better cornering, your bottom bracket drops 6mm and the head tube angle slackens by half-a-degree.

 

Details and Components

2020 Specialized Stumpjumper Evo Pro

There are some pretty cool details on this mountain bike. For example, it has a ribbed chainstay protector that stops chain slap and reduces noise from the drivetrain. If you are fan of the tidy look, the Evo has internal cable routing. They have made it very easy to work with, when it comes to changing cables, by putting tubes inside the frame. This means you just have to push your cables in.

The spec of the 2020 Specialized Stumpjumper Evo Pro is pretty high end. With its Fox front and rear suspension, tough Roval Traverse Carbon wheels, and the fantastic 12-speed SRAM GX Eagle groupset. The brakes are four piston SRAM Code RSC, which means you will be able to stop when you get to the bottom of that big hill you have been charging down.

  1. Pricing is definitely steep, but for me I’m all about longevity. I’d rather spend 6,000 for something that’s going to last rather than spend 1,200 for something I’ll have to replace in a year or two. If the price matches the durability, I’m definitely in it for the long haul. For someone who loves the outdoors and trails, a mountain bike would be a great addition to my overall fitness collection, but as I said, if the bike lasts as long as the potential investment, I’m in. 

    1. Hi Todd,

      Thanks for your comment. Bikes are expensive, but you do get what you pay for. I am still amazed at the punishment that they can take and the situations they get you out of. You might want to check out the Nukeproof Mega. I have one of these and it is super tough.

  2. I’m planning to buy a mountain bike after a friend convinced me to join his group of bikers here in the southern part of the island of Luzon in the Philippines. Our terrains here are perfect for this sport, and quite envious, I’d like to join this friend to have new adventures. With regard to this 2020 Specialized Stumpjumper Evo Pro, I’d like to know if the body of this bike is an alloy or a heavy-weight steel? I think I need one that’s fitted to my body size. I’m 39 years old, weighing 150 lbs. and with a height of just 5 feet and 5 inches.

    1. Hi Gomer,

      This bike has a carbon frame. Most bikes are now made with carbon or aluminium frames for strength and weight. Which size you choose, will be determined by your riding style in this case. You can adjust a this bike to suit your preferences.

  3. Very interesting article! I enjoyed learning about the different models you described. I didn’t really know that there were various aspects that suit individual riders needs. Although I am not an avid trail rider, I appreciate the comparisons you pointed out – especially the grid of features  you have at the beginning. Thanks!
