The all-new Stumpjumper 15 EVO obliterates every trade-off in the trail game. It’s the ‘Bike of the Year’ winning Stumpy 15 you know, turned up to 11—with a longer-travel 160mm FOX fork, external reservoir FOX FLOAT X shock, and a slacker headtube for next-level capability. Devour bumps like a big bike? Check. Short-travel control, playfulness, and efficiency? Double check. A heaping helping of personalization to make it perfect for the only rider who matters—you?

The bike features an M5 alloy chassis with a matching rear-end built around Trail Geometry, a threaded bottom bracket, internal cable routing, sealed cartridge bearing pivots, and 12x148mm dropouts. It includes a SWAT 4.0 storage system integrated into the downtube, along with a head‑tube angle adjustment and full compatibility with SRAM UDH. The frame delivers 145mm of rear travel and uses a 38.6mm alloy seat binder.

Suspension duties are handled by a FOX FLOAT 36 Rhythm fork with a GRIP damper, two‑position Sweep adjustment, and a 15x110mm QR axle. Travel varies by size: 150mm on S1 and 160mm on S2–S6. In the rear, a FOX FLOAT X Performance shock with Specialized GENIE Shock Tech provides a Ride Dynamics Trail Tune, a 2‑position lever, three open‑mode tuning settings, and LSR adjustment, sized at 210x55mm.

Braking comes from SRAM DB8 Stealth hydraulic disc brakes with 4‑piston calipers and 200mm rotors front and rear. The drivetrain uses a SRAM Eagle 70 Transmission including a 12‑speed 10‑52t cassette, Eagle 70 shifter, and Eagle 70 rear derailleur designed for smooth shifting under load. The crankset is an Eagle 70 model with 165/170mm arms, a 55mm chainline, and a 32T chainring, paired with a SRAM 70 Flattop chain and a DUB Threaded Wide bottom bracket.

Rolling on Specialized hookless alloy rims (30mm internal width, tubeless‑ready) laced to DT Swiss Elemental spokes, the bike uses a sealed‑bearing 15x110mm front hub and a Specialized alloy rear hub with a 12x148mm thru‑axle and HG steel freehub. Tires include a Butcher GRID TRAIL T9 29x2.4 up front and an Eliminator GRID TRAIL T7 in size‑specific formats: 27.5x2.4 for S1–S2 and 29x2.4 for S3–S6.

The cockpit includes a 35mm‑bore alloy Trail stem, Specialized Trail grips, and 6000‑series alloy handlebars with 6° upsweep and 8° backsweep—780mm width and 20mm rise for S1–S2, and 800mm width with 50mm rise for S3–S6. The saddle is a Bridge Comp with hollow Cr‑Mo rails, offered in 155mm or 143mm widths. A Xfusion Manic dropper provides infinite adjustability with a two‑bolt head and Remote SLR LE lever, sized at 34.9mm with travel varying by frame size: 125mm (S2), 170mm (S3), and 190mm (S4–S6).
