Stumpjumper 15
Algupära
Stumpjumper on jalgratas, mis alustas mägirattasõitu — Specialized andis selle 1981. aastal välja maailma esimese masstoodetud mägirattana ja originaal on nüüd Smithsoniani instituudis. 43 aastat hiljem, 2024. aasta juulis, tõi Specialized turule Stumpjumper 15 — 15. põlvkonna ja suure konsolideerimise: varasem jaotus Stumpjumper (130mm) ja Stumpjumper EVO (150mm) ühendati üheks 145mm-tagumise / 150mm-esihargiga platvormiks, millel on reguleeritav geomeetria (65,5° kuni 63° peanurk) ja täiesti uus GENIE-tagumine amortisaator, mis töötati välja koostöös Foxiga. GENIE on peamine uuendus: kahekambriline õhkamortisaator, mis käitub põrketsoonis nagu spiraalvedru ja tõuseb löögi lõpus nagu õhkamortisaator — kaotades Specialise andmetel 57% vähem haarduvust kui tavaline õhkamortisaator.
Tehnilised andmed
- Raam
- FACT 11m carbon fiber (Pro/Expert); FACT 12m carbon on S-Works; M5 aluminum alloy on Comp Alloy. FSR (Horst-link) 4-bar suspension layout, SWAT in-frame storage.
- Kahvel
- Fox 36 Factory GRIP X2, 150 mm travel (custom 'Rx' tune); 140 mm on entry S1, 160 mm coil fork on Öhlins/mixed-wheel coil models
- Jõuülekanne
- SRAM X0 AXS T-Type Transmission (1×12 wireless) on Pro; GX AXS / XX AXS on other trims, Shimano XT on select builds
- Pidurid
- SRAM Maven Silver 4-piston hydraulic disc, 200 mm rotors front and rear (Pro build)
- Rattad
- 29" Roval Traverse SL II carbon (Pro); MX/mullet (29"/27.5") on smaller S1/S2 sizes, 27.5" rear compatible via aftermarket link
- Rehvid
- Specialized Butcher (front) + Eliminator (rear); rear sidewall support criticized as light for the bike's capability
- Vedrustus
- Full-suspension 145 mm rear (FSR Horst-link) / 150 mm front; rear runs the Specialized GENIE dual-chamber air shock (Fox Float-based) — ports close at ~70% travel for coil-like small-bump feel plus air-like end-stroke ramp
- Rooliplokk
- Roval carbon handlebar 800 mm (Pro); alloy bar on lower trims
- Sadul
- Specialized Mirror Tech 3D-printed saddle (Pro); 185 mm dropper post — improved seatpost insertion for shorter riders
- Geomeetria
- Adjustable head angle 63°–65.5° (±1° via asymmetric headset cup); chainstay flip-chips adjust BB height ~7 mm; reach 450 mm (S3) / 475 mm (S4); chainstays 435 mm; six sizes S1–S6. Trail-oriented, quiver-killer character.
- Kaal
- ≈13.98 kg (carbon Pro, ~S4 with SWAT); ~14.4 kg with pedals (S3)
Verdikt
- GENIE shock delivers class-leading descending traction — Specialized data claims 57% less traction loss vs a standard air shock; reviewers consistently praise rear-wheel ground contact
- Exceptional versatility: one adjustable platform that replaced both old Stumpjumper and Stumpjumper EVO, covering mellow trail to aggressive enduro-lite riding
- Wide geometry adjustability — ±1° head angle via headset cup plus chainstay flip-chips for BB height — without proprietary tools or angle-set chaos
- Lighter, stiff carbon frame with practical SWAT in-frame storage; efficient pedaling, especially in the shock's Firm mode
- Custom-tuned Fox 36 GRIP X2 fork and tunable mid/end-stroke shock suit a broad range of rider weights
- Rear tire (Eliminator) sidewall support is too light for the bike's downhill capability — many riders will want to upgrade
- Premium pricing; GENIE shock is a Specialized-exclusive part, so service and replacement options are limited vs a standard shock
- Coil-spring/mullet variants alongside the air models create confusing spec overlap across the lineup
- Front end can feel vague/floppy when fully slacked-out for climbing in the slackest setting
- SRAM Maven brake bite point reported to wander; launch-spec saddle comfort faded on long days
