Collection note: The page title reads SIUX ELECTRA STUPA PRO ST4, but the description calls it Siux Stupa Electra Pro ST4 2025, so the word order of the name differs. Balance is stated as medio-alto (spec: MEDIO ALTO), which does not map to a single low, medium or high value, so balance.value is null. The spec lists Tacto de pala: MEDIO, DURO, which agrees with tacto medio-duro. There is also an untranslated label, Translation missing: es.hardness, with the value 7.5/10. Carbono 15K is described as the construction, while the spec line Superficie de pala gives only 15K. No core foam, frame material, weight or thickness is stated. Season is listed as SS25.
