Stumpjumper 15 Alloy
The Stumpjumper 15 Alloy brings the same adjustable trail geometry and six-way geo adjustability as the carbon models to an M5 alloy chassis — at the most accessible price in the Stumpy 15 lineup. Factory coil suspension front and rear delivers consistent, plush trail feel without air spring complexity.
- FOX FLOAT 38 Factory GRIP X2: 160mm — same Kashima Factory fork as carbon Pro model.
- FOX DHX Factory Coil Rear: 145mm, Ride Dynamics trail tune, spring rates matched per size.
- Shimano SLX M7100: 12-speed mechanical — reliable, durable, no batteries needed.
- Mixed Wheels: 29" front / 27.5" rear — nimble and playful for technical terrain.
- Roval Traverse Alloy + DT 370: Hookless alloy rims, 30mm inner width, durable hubs.
- TRP DH-R EVO Brakes: 220mm front / 203mm rear, 4-piston — powerful DH-level stopping power.
- 16.90kg (37 lb): Heaviest Stumpy 15, but most affordable — same geometry and adjustability.
The most accessible Stumpy 15 — alloy frame, Factory coil suspension, mechanical SLX drivetrain. Same trail geometry, same adjustability.
