Introduction to the Specialized Stumpjumper 15 Alloy GX T-Type

For enthusiasts seeking a trail bike that blends versatility, cutting-edge technology, and ride quality that excels across diverse terrains, the Specialized Stumpjumper 15 Alloy GX T-Type is crafted to meet those demands head-on. This Jenson Exclusive model is a perfect companion for riders who crave the thrill of singletrack while desiring an all-around nimble and effective platform for climbing and descending.

Frame and Geometry: Designed for Trail Mastery

The heart of this trail bike is a meticulously engineered M5 alloy frame that combines strength with weight savings. Specialized's signature Trail Geometry is featured here, with a notable 64.5-degree head tube angle that strikes the ideal balance for control on descents and precision on climbs. The frame includes internal cable routing that enhances sleek aesthetics and protects cables from the elements, a threaded bottom bracket for a robust crankset interface, and Boost spacing to optimize stiffness and wheel alignment.

One standout feature of this frame is the aftermarket shock link system, which allows riders to run either 29" wheels front and rear or mix with a 27.5" rear wheel to add playfulness and quick responsiveness to the ride. Impressively, the geometry remains consistent and unaffected by this adjustment, ensuring handling precision regardless of the setup you prefer. The rear suspension travel measures 145mm, paired with either 140mm or 150mm travel front forks depending on your frame size, offering confident absorption of bumps and trail chatter.

Suspension: Fox Float at Its Finest

The Specialized Stumpjumper 15 Alloy GX T-Type comes equipped with a Fox Float 36 Performance fork featuring 150mm of travel and a 44mm offset, delivering smooth and controlled suspension response on uneven terrain. Complementing the fork is the Fox Float Performance rear shock, tuned with Specialized's proprietary GENIE Shock Tech, which optimizes pedal efficiency while providing the necessary compliance for technical trails.

Drivetrain: SRAM GX T-Type 12-Speed Wireless Electronic

The drivetrain on this trail bike is tailored for effortless shifting and a broad gear range, powered by the SRAM GX T-Type 12-speed wireless electronic system. With the ultra-wide 10-52T cassette at the rear, riders can tackle steep climbs without strain and maintain optimal cadence through variable terrain. The wireless shifting setup eliminates cable clutter and maintenance concerns, delivering crisp and reliable gear changes every time. The 32T crankset rounds out a smooth, high-performance system primed for trail challenges.

Braking System: Reliable Control with SRAM Code Bronze Stealth

Ensuring stopping power across technical descents, the bike features SRAM Code Bronze Stealth hydraulic disc brakes augmented by Galfer Wave 203mm rotors. This braking combination provides consistent modulation and strong, confident stopping force, empowering riders to confidently navigate steep or fast trail sections with enhanced safety.

Wheels and Tires: Traction and Durability

Durable and race-tuned, the wheels are Crankbrothers Synthesis Enduro Alloy 29" wheels with Boost hubs. These are paired with aggressive yet reliable Maxxis Minion DHR II 29x2.4" tires, designed for excellent cornering grip and braking traction. The tires come tubeless-ready, allowing for lower psi settings that improve ride comfort, traction, and flat prevention—a critical setup for serious trail riders.

Comfort and Convenience Features

The ride experience is enhanced by a SDG Tellis Dropper Post with 170 to 200 mm of travel, allowing riders to swiftly raise or lower the saddle on the fly, adapting to climbing or descending sections without losing momentum. The Renthal Fat Bar with a 30mm rise and Trail Stem provide ergonomic positioning for long days out on variable trails. WTB Wafel grips and a WTB Silverado Steel saddle complete the cockpit with comfort-centric design.
