Specialized P.4 – 27.5″ Dirt Jump & Slopestyle MTB 2025

The New Era of Dirt: Specialized P.4 (2025)

The Specialized P.4 2025 is the answer for riders who demand more versatility and stability from their freestyle machine. Built with a legendary A1 Premium Aluminum frame, the P.4 transitions to a 27.5-inch wheel platform, providing better momentum and a smoother ride over large-scale sets. If you are looking for a dirt jump and slopestyle MTB that bridges the gap between technical park riding and high-speed trail rhythm sections, the P.4 is the professional tool for progressive aerial progression.

Handling high-impact landings with ease is the 100mm Marzocchi Bomber DJ fork, featuring a dedicated dirt-jump chassis that ensures maximum steering precision. This is paired with a bombproof single-speed drivetrain and oversized rear dropouts that allow for easy chain tensioning and extreme durability during heavy crashes. This configuration ensures unrivaled mechanical simplicity, allowing you to focus entirely on your trick execution rather than worrying about shifting issues or mechanical failures mid-air.

Ideal For: Big Air Jumps, Slopestyle Courses, and High-Speed Pump Tracks

This bike is the ideal choice for freestyle athletes and mountain bikers who want a dedicated jump bike that feels stable and fast on larger features. It is perfectly suited for slopestyle competitions, professional bike park sessions, and riders who prefer the increased rollover and grip provided by 27.5-inch tires. With its sleek, tapered head tube and boost-spaced rear end, it stands as an excellent modern jumper that can handle the massive forces of modern freeride events. Whether you are sessioning a local spot or a world-class course, the P.4 is ready.

Why Choose Specialized P.4 Over Traditional 26″ Jumpers?

Choosing the P.4 means investing in increased stability and speed, as the 27.5-inch wheels carry momentum significantly better through large jump transitions. Unlike traditional dirt jumpers, the P.4 features a highly refined geometry that keeps the chainstays short and the bottom bracket low, maintaining that signature “flickable” feel. This results in a precision-engineered freestyle machine that feels composed in the air and incredibly fast on the landings. Additionally, the frame is dropper-post compatible and includes routing for a rear derailleur if you choose to convert it into a light-duty trail shredder.
