The Stumpjumper 15 Alloy packs all the performance and
versatility of the FACT 11 carbon-framed Stumpjumper 15, but with the
durability of an M5 aluminium alloy frame. You’ll still enjoy the six-way
adjustable geometry, SRAM UDH compatibility, and SWAT door integration for
ultimate customization and convenience. Plus, the Stumpjumper 15 Comp Alloy comes
equipped with the Fox Genie Shock, delivering a smooth and controlled ride.

The Stumpjumper 15’s geometry is similar to the award winning Stumpjumper EVO which offers a confident riding position. You get big bike capability when you need it, a nimble feel in tight sections, and lively, efficient climbing manners. The generous cockpit centres you on the bike, optimizing traction and corner control. The low bottom bracket and slack head tube angle keep things stable in the rough.

The Stumpjumper now features 6-way adjustable geometry. You can easily adjust the head angle between 63° and 65.5° via a unique eccentric upper headset cup. You can also fine tune the bottom bracket height and chainstay length using the flip chip in the rear stays. This means that you can personalize the feel of the bike to your own preferences, or for particular trail conditions.

The Stumpjumper 15 uses Specialized’s S-Sizing system which allows you to select the size to suit your riding style. It’s nice to see that chainstay length is size specific too on this new bike.

*The four larger sizes come with 29” wheels front and rear while the smaller S1 and S2 sizes come with a 27.5” rear wheel and a 29” front wheel. There is one exception to this in that that there is one model with an Ohlins coil shock that comes with a 27.5” rear wheel in all sizes. An aftermarket shock link is available if you want to fit a 27.5” rear wheel on a full 29er.
