Stumpjumper Alloy vs. Comp Alloy: Compared

Mountain biking is a thrilling and rewarding sport that requires a reliable and high-performance bike.

There are many factors to consider when choosing a mountain bike, such as the frame material, suspension system, wheel size, geometry, and components.

We will compare two popular models from Specialized, the Stumpjumper Alloy and the Stumpjumper Comp Alloy, and see how they differ in terms of features, performance, and price.


The Stumpjumper Alloy and the Stumpjumper Comp Alloy are both part of the Stumpjumper family, which is Specialized’s flagship line of trail bikes.

They are designed to handle a variety of terrain and riding styles, from smooth singletrack to technical rock gardens.

Both bikes share the same frame geometry and suspension design, which is based on the innovative Sidearm frame that connects all three mounting points of the rear-end and shock to the frame.

This results in a stiffer and lighter rear-end that improves handling and responsiveness.


There are also some key differences between the two models that affect their overall performance and value.

Frame material

The Stumpjumper Alloy has an aluminum frame, while the Stumpjumper Comp Alloy has a carbon front triangle and an aluminum rear triangle.

Carbon is a lighter and stronger material than aluminum, which means that the Stumpjumper Comp Alloy has a lower weight and a higher stiffness than the Stumpjumper Alloy.

This translates into better acceleration, climbing, and maneuverability on the trails.

The Stumpjumper Comp Alloy has higher-end components than the Stumpjumper Alloy, such as a SRAM NX Eagle 12-speed drivetrain, a RockShox 35 Gold RL fork, a FOX Float DPS Performance rear shock, and SRAM Guide R hydraulic disc brakes.

These components offer smoother shifting, more precise steering, better shock absorption, and more powerful braking than the components on the Stumpjumper Alloy, which include a Shimano Deore 11-speed drivetrain, a RockShox Recon RL fork, an X-Fusion 02 Pro RL rear shock, and Shimano MT-200 hydraulic disc brakes.


The Stumpjumper Comp Alloy costs $3,199 USD, while the Stumpjumper Alloy costs $2,799 USD.

This is a significant price gap that reflects the difference in quality and performance between the two models.

The Stumpjumper Comp Alloy is a more premium bike that offers more features and benefits than the Stumpjumper Alloy.

However, the Stumpjumper Alloy is still a great bike that offers a lot of value for its price. It is a solid and versatile bike that can handle most trail conditions and challenges.

Which bike should you choose?

The answer depends on your personal preferences, budget, and riding goals.

If you are looking for a lighter and faster bike that has higher-end components and can tackle more demanding trails, then the Stumpjumper Comp Alloy might be the better option for you.

Yet, if you are looking for a more affordable bike that still offers a great performance and durability on the trails, then the Stumpjumper Alloy might be the better option for you.

Either way, you can’t go wrong with either of these bikes. They are both excellent choices for mountain biking enthusiasts who want to enjoy the thrill of riding on any terrain.
