Can the Enduro's little brother hang in the steeps and deeps of The North Shore?

The Stumpjumper EVO got a complete overhaul for 2021, taking it from a dedicated long and slack brawler to a genre-bending chameleon of a bike. 150mm FSR...

The Specialized Stumpjumper EVO Elite Alloy enters our 2022 trail bike group test as the only alloy full-susser.
Elegant aluminium bike without compromises
Conveys huge amounts of confidence
Intuitive handling
Dropper post can’t be fully inserted into the frame
Not exactly a rocket uphill

The Specialized Stumpjumper Evo Alloy gets all the cool things that the carbon Stumpjumper has had for a few seasons now.

Specialized has taken all of the performance, adjustability and features of its carbon Stumpjumper EVO and offered them in a more affordable M5 aluminum package for 2022.

The Specialized Stumpjumper Evo Comp Alloy has one of the smartest metal frames we’ve seen, but is that quality reflected in the specs?
Excellent easily tuneable geometry
Great aggro tire choice
Short seat tube for size switching
Solid climb mode
Stiff power transfer
SWAT and geometry switching add cost
Slow free hub pick up
Chunky weight

At The Loam Wolf, we’d rather have a bike that rides well than a bad bike made from carbon fiber. Read a full review on the Specialized Stumpjumper Evo Alloy!
Aluminum
SWAT Door
Comfortable and confident
Playful and fun to ride
Fast
Big geo adjustments
Value is debatable

It's worth mentioning that the Stumpy EVO Alloy was the longest-travel bike we tested in the batch of 130mm to 150mm trail bikes this Field Test, so it's a bit more bike than anything else we're reviewing this week.
So, so adaptable - and the geo adjustments are easier than on some other bikes
SWAT box is the biggest and the best of the in-frame storage boxes out there
Good value and smart spec
Good crossover trail-enduro option
There's no true top-end build, and it would be so good to see more aluminum bikes with fancy spec options
A tad heavy if we're counting grams
