P.1
Specialized
Dirt Jump
P.1 is an alloy dirt jump mountain bike (2024), from Specialized. It is best suited to riders looking for a balanced off-road setup, with a setup that gives you a balanced riding position, while being more at home in gravity-focused bike park riding. Based on the metrics, key strengths are strong value-for-money versus many similar bikes and strong speed potential on smoother terrain. Relative to category specialists, the trade-off is a firmer ride feel than comfort-first options and a setup that favors simplicity and efficiency over plush bump absorption.
