Summary

The Specialized Stumpjumper is a versatile trail bike praised for its balanced handling, effective suspension, and innovative features like the SWAT storage system. It excels in traction and control, especially with its 6Fattie tires, making it a blast on descents and technical climbs. While it offers a fun and capable ride, some riders note the added heft of plus-size tires and the need for tire pressure adjustments.

Pros
  • S.W.A.T. system for storage solutions

  • Effective suspension performance

  • Excellent traction and control with 6Fattie tires

  • Balanced and fun handling

  • Innovative features enhancing ride quality

Cons
  • Added heft and rotational mass of plus-size tires

  • Tire pressure adjustments needed for optimal performance

  • More basic shock on some models

  • Not ideal for longer XC rides or higher speeds

Key Quotes
The 6Fattie rides like mad, it’s capable of taking your mountain biking to an unprecedented level, you’ll corner much harder, launch down descents with reckless abandon and climb up things you never thought possible. It’s a blast.

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 Comp 6Fattie (2016) review - MBR

Nov 2015 · Jamie Darlow

Specialized Stumpjumper FSR Comp 6Fattie is one of only a handful of plus sized full suspension bikes. Does it make the most of wider rear tyres?

Highs
  • Traction and control hit new highs on certain terrain. Can be winched up ridiculously steep pitches

Lows
  • Tyres can be too bouncy and float in mud

Ok, you’re out having a great mountain bike ride, the feeling of going really fast is fantastic. Then you get a little bit carried away. All of a sudden the trail turns slippery and you’re going way too quick, but don’t worry you’re going to make it through: you’ve got 3” tyres. Riding a bike with …

Highs
  • Takes riding to another level.

  • It climbs anything, crushes corners and blasts descents safely and confidently.

  • Any type of rider can benefit from the big tyres.

Lows
  • Round tyres feel vague and less precise.

  • Not necessary for flat or smooth trails.
