2022 Specialized Stumpjumper Evo Alloy

The Specialized Stumpjumper and Stumpjumper EVO were overhauled in a big way for 2021, with new suspension kinematics and handling, with geometry adjust features and a quest to create the perfect trail bike.

But, until now they were only available in carbon fiber, which put them at a higher price point and did put some riders off who favour the benefits of an aluminium frame.

All about the Specialized Stumpjumper and Stumpjumper EVO

Specialized have just released two new Stumpjumper Evo models for 2022, the Stumpjumper Evo Comp Alloy ($5800), and the Stumpjumper Evo Elite Alloy ($8500). And while the alloy versions of carbon frames sometime miss the finer points of the carbon bretheren, that is not the case with the Stumpjumper Evo models. You get the same 150mm of travel, the same suspension kinematics and shock tunes, S-sizing, geometry adjustment at the headset and Horst link, full routed cable and hose guides and the SWAT frame storage.

The Specialized M5 Alloy that both frames use is a class-leading alloy, so while this frame isn't carbon fiber, it's a high quality aluminium alloy that Specialized have spent decades fine-tuning. And that's why they have been able to manipulate the material so much to deliver all the features that usually need a carbon mould.

The latest Stumpjumper EVO design was all about progressive geometry and sophisticated suspension kinematics. And the alloy models offer the same high performance trail traits that deliver confidence, capability and control.

Travel remains the same with 160mm up front and 150mm in the back. The rear end is designed for small bump sensitivity while eating up square edged hits. The leverage rate doesn't skimp on mid-stroke support, and the whole kinematics offer the higher anti-squat figures as the carbon models – which means less squish on the pedal ups.

 
Specalized said that three separate machining processes were needed for the headtube during construction, so they could incorporate the adjustable headtube cups. The downtube is hydroformed for the integrated SWAT box – but still gives plenty of strength and rigidity.

 
The Stumpjumper EVO alloy has six geometry settings so you can fine tune the geometry to suit you and your terrain – or the terrain that you're heading to ride. The head angle can be adjusted between 63 – and 65.5-degrees, the bottom bracket height can be moved up or down by 7mm. An aftermarket shock link allows the standard 29” rear wheel to be swapped out for a 27.5” hoop, without impacting other handling dynamics. 

The S-sizing is common on almost all Specialized dual-suspension bikes now, and it rolls into the Stumpjumper EVO alloy as well. With 6 sizes, you can base your fit on reach, and not standover height.
 

Models of the Stumpjumper EVO Alloy

The two models are the EVO Comp Alloy at $5800, and the EVO Elite Alloy at $8500.

The Comp has predominantly a SRAM Eagle NX group set with CODE R brakes. The fork is a Fox 36 Rhythm, while the rear shock is a Fox Float X Performance unit. Wheels are Specializeda lloy with 30mm internal rims and alloy sealed bearing hubs.

The Elite bumps up to Fox Factory 36 fork and Factory Float X shock, with SRAM GX Eagle 12-speed (and 10-52 cassette) with CODE RS brakes. Wheels are Roval Traverse 29 alloy, which also means you get DT Swiss 370 hubs.

In a time where the top end bike prices are getting higher, we're happy to see some alloy options of Specialized's very popular Stumpjumper EVO. These aren't cheap, but they are trail bike options with progressive geometry, all the frame features you could want, and some very sound build kits.
