Plus Size bikes have been the hot ticket since we saw their launch into the mountain bike market at Sea Otter, and we have been eager to get our gloves on them, and in this case the Specialized Stumpjumper FSR Comp Carbon 6FATTIE.  Yes the title has quite a footprint, but then again so do the tires, so its fitting.  The flagship Stumpjumper that has an established reputation of being one of the best mountain bikes on the trail, has taken the Plus Size concept and made it a part of the Specialized legacy.

Specialized offers the Stumpjumer 6FATTIE in a few options, starting at $3,500 for the entry level aluminum and topping out at $8,600 for the S-Works version.  Our test bike is the starting point for the carbon versions and retails for $4,500.  With a full SRAM GX 1×11 build kit and Fox suspension, and Command post, the pricing is pretty competitive. Although we’d imagine the S-Works version is pretty sweet.

This front triangle uses Specialized’s FACT 9mm carbon Trail Chassis with an M5 alloy rear triangle with 148mm BOOST spacing.  The FSR 6-pack link, internal cable routing, SWAT Door, and compact geometry, finish up the frame build and make this look like a traditional Stumpy.

The Fox Float Performance DPS shock allows for 135-millimeters of travel while the FOX 34 Performance Plus fork allows for 150-millimeters of travel in the front.  Combine that suspension with 3-inch wide tires and you have one incredibly smooth ride.

We are still in the throws of testing, but so far its been fun. If there is anything that we can truly say about this bike thus far, its that it is pure fun, there has yet to be any shortage of smiles or jovial emotions.  Between the big suspension and wide tires we have noticed that this bike is very capable and will eat up just about any rock in the trail.  Though it doesn’t rain much here in Southern California, we were able to get a ride in after a good drenching and really take advantage of the much needed traction that the Plus Size tires have to offer.  Keep your eyes open for our full review and opinions on this rig in a future issue of Mountain Bike Action.

The wrecking crew strives to put as many miles on each test bike before we write a full review. Watch for the full write-up on this bike in the coming pages of Mountain Bike Action.
