RockShox SID Ultimate Race Day 29" suspension fork

Climb mountains. Descend hills. The SID Ultimate isn't like other XC forks. It's lighter than ever before, with a stiff 35mm chassis that holds its line when you're pushing the limits. New Race Day 2 damper features two compression settings (2P) – rock solid locked out, and plush open, all at your fingertips. The SID adapts to everything from full-gas cross-country to shredding forest trails thanks to the new higher volume DebonAir+ air spring, sensitive at the top of the travel with tunable options.

The 35mm inner leg diameter design is the ideal combination of lightness and stiffness for modern XC bikes

Variant RockShox SID Ultimate Race Day 29"odpružená vidlica, 120 mm, gloss black

SK Dobrý deň, je táto vidlica podľa vás použiteľná aj klasické HT XC so 100mm zdvihom (69,5 ° uhol hlavovej rúrky, axle-to-crown približne 507 mm)? Dala by sa geometria rámu čo najviac zachovať napr. odstránením spacerov spod predstavca alebo napr. použitím 1,5 ° angled crown race? Prípadne upgrade len na 110mm je lepší možný variant?

Variant RockShox SID Ultimate Race Day 29"odpružená vidlica, 120 mm, gloss black

SK Dobrý deň, ospravedlnujem sa za neskorú odpoveď.

Áno, RockShox SID Ultimate Race Day 120 mm je možné použiť aj na klasické XC hardtaily so 100 mm zdvihom, ale treba počítať s miernou zmenou geometrie – hlavový uhol sa položí približne o 1°, čo ovplyvní ovládateľnosť (bude stabilnejšia z kopca, ale trochu pomalšia v strmých stúpaniach a tight trailoch).

Ak chcete geometriu zachovať čo najbližšie k pôvodnej: Odporúčame odstrániť spacery pod predstavcom (znižuje výšku kokpitu).
Prípadne zvážiť zníženie zdvihu na 110 mm (vymenením interného air shaftu vo vidlici) – tým sa zníži predná časť a geometriu zachováte lepšie. Angled crown race v tomto prípade neodporúčame, zmenil by geometriu ešte viac.

Celkovo – 120 mm vidlica je použiteľná, najlepšie však s úpravou na 110 mm pre vyvážený výsledok.
