Product Details

Ruthless Progression Progression only starts when you do. This totally redesigned P.Series gives riders of all sizes a jumping off point (pun intended) to the world of dirt jump bliss. Its performance-based geometry and cockpit put riders at ease whether learning the ropes at the pump track or stomping the final trick jump on a world stage. Specialized’s approach to these robust bikes centers around delivering a simple, high-quality platform that's versatile for all riders, and packs a serious high-performance punch. SLEEK SIMPLICITY — The latest and greatest levers, adjustment switches, and complex cabling have their place—but not here. For the rider focusing on progression, eliminating every other variable is paramount. Starting with the durable lightweight alloy frame, P.Series stands up to unique demands of a bike that only dirt jump riders know. It’s going to hit the ground. A lot. SIZED FOR ALL — In such a niche corner of the cycling world, a purpose-built bike like the P.Series used to be available in minimal size options. That’s why we took a step back to design a new range of inclusive sizes. From a 20-inch tire legit dirt jumper to a 27.5-inch category-crossing trail cruiser that can be backflipped. REIMAGINE YOUR RIDE — Instead of compromising on its heart and soul (flipping and whipping through the air), we expanded its capability. It’s dropper ready, derailleur compatible, and uses adjustable dropouts. You can ride it out your door all the way to the bike park—and make a pitstop to session along the way. TOUGH TECH — Built with a boost spaced rear end for added stiffness, this burly wheel setup along with tapered headtube, and threaded bottom-bracket make P.Series extremely resilient and easy to maintain. Wrapped in its new 2.1” Kicker tire—but accepting up to a 2.35” trail tire—you’ll find grip and make speed anywhere. Marzocchi Bomber, high performance and tunable.

Lightweight and strong single-speed P.Series wheelset.

Specialized Kicker tires find grip anywhere, street, dirt, or at the skatepark.
