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...

Specialized Stumpjumper Evo Comp Alloy review: we ride and rate the latest edition

Feb 2022 · Guy Kesteven

The Specialized Stumpjumper Evo Comp Alloy has one of the smartest metal frames we’ve seen, but is that quality reflected in the specs?

Highs
  • Excellent easily tuneable geometry

  • Great aggro tire choice

  • Short seat tube for size switching

  • Solid climb mode

  • Stiff power transfer

Lows
  • 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!

Highs
  • Aluminum

  • SWAT Door

  • Comfortable and confident

  • Playful and fun to ride

  • Fast

  • Big geo adjustments

Lows
  • Value is debatable

Field Test: Specialized Stumpjumper EVO Alloy - The Golden Retriever of Bicycles

Dec 2021 · Alicia Leggett

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.

Highs
  • 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

Lows
  • 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

  • Star ratchet issue with the rear hub prior to Field Test
