Specialized S-Works Stumpjumper - 2026, S4/Large

Specialized S-Works Stumpjumper — Size S4 (Large) · 2026

Carbon Full Suspension MTB · XTR Di2 · Carbon Wheels

The S-Works Stumpjumper represents the pinnacle of Specialized’s trail performance lineup — a lightweight carbon chassis engineered for balance, responsiveness, and aggressive all-mountain capability. This S4 (Large) build delivers elite-level components and modern geometry for riders who want top-tier performance without compromise.

The bike features a Shimano XTR Di2 12-speed drivetrain paired with a 32T chainring and 10–51 cassette, delivering crisp electronic shifting and wide-range gearing. Braking is handled by powerful Shimano XTR 4-piston brakes, ensuring confident stopping on steep and technical terrain.

Suspension is premium throughout:

• FOX Float 36 Factory fork (160mm travel, Kashima coating)

• FOX Float DPX rear shock (150mm travel)

Rolling on Roval Traverse SL II carbon wheels with Specialized Butcher GRID Trail 2.4 tires (tubeless setup), the bike combines traction, stiffness, and durability. Additional highlights include a FOX Transfer AXS dropper post, Race Face Era carbon handlebars, 40mm stem, and a Specialized S-Works Power Mirror saddle.

Weight: approx. 30 lb

Fit range: approx. 5’9”–6’2”

With approximately 1,000 miles, the bike remains mechanically excellent. A full frame protection wrap (about 99% coverage) helps preserve the carbon frame, with only normal cosmetic wear consistent with typical mountain bike use.

Why we love it

This is a true no-compromise trail machine — lightweight S-Works carbon, electronic XTR shifting, Factory-level suspension, and carbon wheels all in one package. It’s equally at home on technical climbs, fast flow trails, and aggressive descents. For riders seeking elite performance with modern trail versatility, this build stands at the top of the category.
