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.

Specialized Stumpjumper FSR Comp 6Fattie (2016) review - MBR

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.
