The Stumpjumper 15 EVO Comp Alloy suits intermediate to advanced riders who want a trail bike that can handle chunky, technical descents on trails like Hydraulink or Okanagan Mountain Park without feeling sluggish on the climbs back up. Its adjustable geometry and mixed-wheel option make it especially appealing to riders who like to fine-tune their setup for different terrain rather than running a one-size-fits-all trail bike.

Our team at Fresh Air will help you find the right fit in-store at both Kelowna locations. Stop by to work with one of our experienced staff members, or call 250-763-3425.

Our team will set up your FOX FLOAT X shock and FLOAT 36 fork with sag, rebound, and compression tuned to your weight and riding style, and can walk you through the GENIE technology's tuning range so you get the traction and bottom-out resistance you want. We'll route and set up your X-Fusion Manic dropper post, and get your tubeless tire setup dialled in for local trail conditions. If you want to explore the six-way geometry adjustment or mixed-wheel setup, we can walk you through those options too. Drop into Fresh Air Pandosy (555 Groves Ave) or Fresh Air Dilworth (1656 Dilworth Drive), or book an appointment online.

Q1: What size Specialized Stumpjumper 15 EVO Comp Alloy do I need?
Specialized offers the Stumpjumper 15 EVO in six sizes, S1 through S6, and sizing is based on your height and preferred reach rather than traditional inseam measurements. Check Specialized's geometry chart for exact figures, or come into either Fresh Air location and our team will get you set up on the right size.

Q2: Is the Stumpjumper 15 EVO Comp Alloy right for Hydraulink or Okanagan Mountain Park?
Yes — with 145mm of rear travel, a 160mm-travel fork, and aggressive Butcher/Eliminator tires, the Stumpjumper 15 EVO is well suited to the technical descents and climbs found at Hydraulink Trails and Okanagan Mountain Park.

Q3: How do I set up the suspension on the Stumpjumper 15 EVO Comp Alloy for my weight and riding style?
Suspension setup starts with sag — typically 25-30% on the FOX FLOAT X rear shock and FLOAT 36 fork, adjusted for your weight and how aggressively you ride. Our team can dial in sag, rebound, and compression settings in-store, and walk you through how the GENIE technology's tunability affects mid-stroke support and bottom-out resistance.
