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.

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
