HOW TO SET UP

Our team will set up your FOX FLOAT X Performance Elite shock and FLOAT 36 Performance Elite 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 also pair your Shimano XT Di2 electronics, set up your PNW Loam dropper post, and get your tubeless tire setup dialled in for local trail conditions.

FAQ

Q1: What size Specialized Stumpjumper 15 EVO Expert Di2 do I need?
Specialized offers the Stumpjumper 15 EVO Expert Di2 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 Expert Di2 right for Hydraulink or Okanagan Mountain Park?
Yes — with 145mm of rear travel, up to 160mm up front, and aggressive Butcher/Eliminator tires, the Stumpjumper 15 EVO Expert Di2 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 Expert Di2 for my weight and riding style?
Suspension setup starts with sag — typically 25-30% on the FOX FLOAT X Performance Elite rear shock and FLOAT 36 Performance Elite fork, adjusted for your weight and how aggressively you ride. Our team can dial in sag, rebound, high- and low-speed compression settings in-store, and walk you through how the GENIE technology's tunability affects mid-stroke support and bottom-out resistance.
