{"product_id":"2025-specialized-stumpjumper-15-alloy-bike-933257","title":"2025 Specialized Stumpjumper 15 Alloy Bike","description":"\u003cp\u003eBuilt for riders who want one bike to handle everything, the Specialized Stumpjumper 15 Alloy (2025) blends a rugged M5 aluminum frame with a mullet wheel setup that pairs a 29-inch front and a 27.5-inch rear. Roughly 150mm of fork travel and 145mm out back let it plow through rough sections while staying nimble on tight, twisty singletrack. The payoff is a planted, confidence-building ride that still loves to be pushed.\u003c\/p\u003e\u003ch3\u003eWhy we like it:\u003c\/h3\u003e\u003cp\u003eThe mixed-wheel layout is the real trick here, giving you the rollover and grip of a big front wheel with a smaller rear that whips through corners and pops off features.\u003c\/p\u003e\u003ch3\u003eWho it's for:\u003c\/h3\u003e\u003cp\u003eIdeal for trail and all-mountain riders chasing a versatile rig that climbs efficiently and descends with composure, from mellow flow trails to chunky backcountry lines.\u003c\/p\u003e\u003ch3\u003eHighlights:\u003c\/h3\u003e\u003cp\u003eThe frame is Specialized's M5 alloy in a mixed 29\/27.5 wheel configuration. Suspension comes from a RockShox Psylo Silver fork with roughly 150mm of travel matched to an X-Fusion O2 Pro RL air shock delivering about 145mm at the rear. Shifting is handled by a Shimano Deore M6100 12-speed drivetrain with a wide 10-51 cassette for steep climbs, and Shimano MT420 four-piston hydraulic disc brakes with 180\/203mm rotors supply the stopping power.\u003c\/p\u003e\u003ch3\u003eThings to consider:\u003c\/h3\u003e\u003cp\u003eThis is a versatile mid-travel trail bike that climbs and descends confidently. It is not a dedicated downhill or long-travel enduro bike, so the most extreme, roughest terrain may call for more travel.\u003c\/p\u003e","brand":"Specialized","offers":[{"title":"Satin Cast Blue\/Dove Grey \/ S1","offer_id":50166243983656,"sku":"933257|CSTBLU_DOVGRY|S1","price":2299.95,"currency_code":"USD","in_stock":false},{"title":"Satin Cast Blue\/Dove Grey \/ S2","offer_id":50166244016424,"sku":"933257|CSTBLU_DOVGRY|S2","price":2299.95,"currency_code":"USD","in_stock":true},{"title":"Satin Cast Blue\/Dove Grey \/ S3","offer_id":50166244049192,"sku":"933257|CSTBLU_DOVGRY|S3","price":2299.95,"currency_code":"USD","in_stock":false},{"title":"Satin Cast Blue\/Dove Grey \/ S4","offer_id":50166244081960,"sku":"933257|CSTBLU_DOVGRY|S4","price":2299.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/5135\/6456\/files\/2025-specialized-stumpjumper-15-alloy-bike-933257-1-933257.jpg?v=1786638512","url":"https:\/\/checkout.skiessentials.com\/products\/2025-specialized-stumpjumper-15-alloy-bike-933257","provider":"SkiEssentials","version":"1.0","type":"link"}
