A bike with lower gearing will be easier to ride up steep hills, while a higher top end means it will pedal faster down hills.

Summary

The Specialized Stumpjumper excels as a versatile cross-country bike, praised for its playful and fun handling that inspires confidence on various trails. Its supple suspension and balanced geometry provide a smooth ride, while innovative features like the SWAT storage system add practicality. However, some reviews note issues with tire performance in mud and a tendency for the rear shock to rush through travel on big hits.

Pros
  • Playful and fun handling

  • Supple suspension performance

  • SWAT storage system

  • Excellent traction on climbs

  • Balanced and predictable geometry

Cons
  • Tires can be bouncy and perform poorly in mud

  • Rear shock may rush through travel on big hits

  • Low bottom bracket leads to pedal strikes

  • Slightly sluggish compared to bikes with regular tires

Key Quotes
It’s a bike that works in harmony with all its angles and travel, never seeming like it’s too much or not enough of anything.

the 6fattie is the most fun I have ever had on a mountain bike

Supple suspension, tacky tyres and a sweet balance of slack and sharp – the Stumpy rules the trails.
Flow Mountain Bike logoFlow Mountain Bike
The Stumpjumper has a really lively, playful feel on descents, and rides with great agility even with those chubby tires.

Specialized Stumpjumper FSR Expert Carbon 6Fattie (2017) review - MBR

Apr 2017 · Danny Milner

The Specialized Stumpjumper Carbon 6fattie is short by modern standards and with other options now available, upsizing may no longer be an easy get out.

  • Not lacking in fun

Tested: Specialized Stumpjumper FSR Expert 6Fattie

The main question to ask ourselves is … why? Why do we ride? Why do you ride? Why spend so much of your hard-earned money on bikes and gear? Why not just hop on your old steel klunker and head out for hours and hours of ripping up our favorite techy singletrack?

Specialized Stumpjumper FSR Expert 6Fattie Review

Aug 2016 · Christoph Bayer

There are just a handful of bikes with a history that can compete with the Specialized Stumpjumper: over the past few years it’s undergone revision after revision, wheel sizes have come and gone, and the Stumpjumper has had them all. Right now it’s on the market in 27.5″, 29″ and 27.5+. We’ve put the burlier […]

[First Ride] Specialized Stumpjumper FSR Expert 29"

Jul 2015 · Ian Collins

[ad3] Last month we spent a few days with Specialized in Northern California for the launch of the new Camber. During that same week, we also had the opportunity to spend some time aboard the new Stumpjumper 29″. The classic trail slayer got some ground breaking new updates. Specialized did away with EVO models and just has two Stumpy offerings : 150mm/27.5″ & 135mm/29″. The new Stumpjumper was also the first bike to see the SWAT door, a downtube storage compartment that is accessed by way of a trap door under the bottle cage. Inside the downtube you can put

First Ride / First Look: Specialized Stumpjumper S-Works FSR 6Fattie

Jun 2015 · Zach Overholt

Last year at this time, the concept of a 27.5+ wheel size was littler more than a rumor – another feather in an already very full cap. In a very short period of time middle fat sizes have gone from ideas to full blown bikes. While the bigger companies have typically been more reserved when it comes …
