Specialized P.4 bicycle 2024

This totally redesigned P.Series gives riders of all sizes a jumping off point to a life on bikes. The lightweight, but tough alloy frame is designed to take all the hits and keep rolling—across all frame and wheel size options. Our approach to these robust bikes centers around delivering a simple, high-quality platform that's versatile for all riders, and packs in category-first features that make a difference to the rider. 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.  Instead of compromising on its heart and soul (flipping and whipping through the air), Specialized 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. 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.

Sleek Simplicity
Featuring a modern, streamlined design, P. Series is a utilitarian tool for progression. Its durable alloy frame and internal cable routing help it roll away from anything. Find your size easily through a range of frame sizes and wheel options from 20” to 27.5”.

Truly Versatile
However you ride, P. Series can adapt. Run it as a single speed, or geared bike to open up your options. And when the situation calls, P. Series can accept up to 2.35” trail tires and a dropper post.

High Performance
New to P. Series—a boost hub—gives added stiffness and a reliable pop platform. Its dual thru-axles and a tapered headtube round off the burly package, while a threaded bottom-bracket allows for quick upgrades and easy servicing.
