Specialized P.4 Dirt Jumper Frame (Satin Rusted Red) (27.5″) (25″ eff)

Specialized P.4 27.5″ Dirt Jump Frame Description:

Specialized took their iconic P.3 DJ frame and scaled it up a bit for 27.5″ wheels. This is ideal for riders who are: a bit taller, looking for something to carry a bit more speed, and/or those mountain bike riders not looking to stray too far away from the 29″ wheels they are so used to.

The P.4 Dirt Jump Frame is constructed from high-grade, lightweight aluminum. The frame boasts expertly tuned geometry that strikes the perfect balance between stability and agility.

Your bike is an extension of your personality and riding style, and the P.4 Dirt Jump Frame empowers you to make it uniquely yours. The P4 frame uses boost rear spacing, sliding drop outs, and accepts a derailleur, allowing you to run gears if you choose. If you do add gears, you might as well add a dropper post as this frame is dropper post compatible as well! To keep things clean, the frame is designed with internal cable routing.

Dominate the dirt jumps, own the pump tracks, and redefine what’s possible with a frame that’s built to push the your boundaries.
