Specialized Stumpjumper FSR Expert Carbon Evo 29 Review

The Stumpjumper FSR is a common bike on our trails here in Texas. It’s a full suspension 29er do-everything bike capable of anything from the weekend XC race to a trip full of colorado riding. Here’s the specs on this bike.

As far as I understand all specs from the Specialized website are exactly what I rode as well.

How It Rides

The Stumpjumper FSR Expert Carbon Evo 29 is definitely the bike with the longest name, and similar to its name it also sports some pretty long travel with 135mm in rear and 140mm in the front. To be honest I feel that is too much travel for most of Texas, but a lot of the riders in Texas really like the slacker angles and  long travel. Casey Fry one of the consistent readers and commenters on this site highly endorses it as one of the most playful 29ers he has ever ridden. So while the long travel isn’t really for me, it is a well-loved bike.

Technically, this bike is more of an All-Mountain bike than a XC or cross country bike and you can tell that when you ride it.

The Specialized Stumpjumper FSR Expert Carbon Evo 29 rides very well, but I could tell that the bike had a lot of suspension sway while riding on straights. The travel just wasn’t controlled as well as bikes like the Pivot Mach 6 or Yeti SB75. I could feel a lot more bouncing and movement than I’m used to. Now, that turned out to be a lot of fun through the whoops sections and during the one downhill section that the course had. Bumps and rocks in the trail felt like nothing, and between the big travel and the big tires it was among the smoothest riding bikes I took out.

One thing I do want to point out is that this bike felt very chunky. In my immediate comments on the TXMTB Facebook page afterwards I mentioned that it needs a new owner diet. I would imagine that this bike comes in around 28-32 pounds from the way it felt and rode. I didn’t realize that this was a CARBON bike until I started writing this recap. Unbelievable that it felt that heavy. But it is only the front triangle that is carbon, the rear triangle is still alloy. Most of the time while riding I didn’t notice it too much, but it did seem to give the weighty feedback while climbing and really trying to pick up tempo.

Something that really impressed me with this bike is the AUTOSAG feature. Specialized has had it out there for a couple of years, but this was the first time I have experienced it. It was one of the coolest things that I saw and forgot to mention during initial coverage. This concept automatically adjusts the sag to 20%. All you have to do is overfill the rear shock by 30-50psi, sit on the bike on and depress the valve pin for autosag. It automatically detects your body weight, empties the negative chamber and releases enough air to properly set the sag at 20%. Then just cycle the shock a few times to refill the negative chamber and your ready to go.

Autosag is a very, very cool feature that really impressed me with how easy it was and makes it quick and easy for newer riders to jump on and ride quickly rather than worrying about sag setup. However, for those of us that know what pressure we like to ride at it really isn’t much use and would probably take more time than the traditional setup.

Here’s a quick side point, and something that really interested me with the big S. They have zero 27.5 models. I find it really interesting that one of the industry heavyweights is sitting back and just watching, but as some other commenters reminded me, they also came to the 29er party late as well.

Overall Thoughts

The Specialized Stumpjumper FSR Expert Carbon Evo 29 is too long of a name first of all. I’m sick of typing it. But it’s a good bike for anyone that likes a plusher ride. It really impressed me with the ease of use on Autosag for new riders and bike owners, also the plush travel felt really great on rough terrain and on sections where you might be getting a little bit airborne.

Overall I don’t think this is an ideal bike for a predominantly XC focused rider in Texas but it is a good bike. For an XC rider I would recommend something with less travel, or better controlled travel, to maximize their efficiency on the trail.

I definitely recommend you get to a local dealer or a Specialized demo in your area to test ride one for yourself because your ride may be massively different from mine.
