Specialized Stumpjumper Pro - 2023, S4/Large

The 2023 Specialized Stumpjumper Pro is among the world's best trail bikes, sitting just below the flagship S-Works. It targets aggressive riders who want high performance on technical terrain. Specialized, founded in 1974 in Morgan Hill, California, has been shaping mountain bikes for over five decades. The S4 frame is built from Specialized FACT Carbon 11m for a stiff, lightweight ride. It pairs 130mm of rear travel with a Fox 34 Factory fork running 140mm of front travel. The drivetrain is SRAM X01 Eagle AXS, a fully wireless 12-speed electronic groupset with AXS Rocker Paddle shifters. SRAM G2 RSC hydraulic disc brakes and Roval Traverse carbon wheels complete the premium spec. Front and rear Specialized tires — Butcher Grid T9 and Purgatory Grid T7 — are tubeless-ready via 2Bliss. Notable component swaps include an aftermarket Deity stem and a Bike Yoke dropper seatpost; pedals are not included.
