    Le corone OctaOne sono state progettate e realizzate per essere utilizzate nei sistemi con singola corona anteriore 9-10-11-12 velocità (Sram T-Type 12s escluse).

    Sono compatibili con tutte le pedivelle dotate di attacco standard a 4 fori con girobulloni 104 mm.

    Extralite OctaOne 104 mm BCD Monoring

    Le corone sono realizzate dal pieno tramite sofisticate lavorazioni a controllo numerico a partire da una lastra di pregiato Alluminio 7075T6 ed in seguito anodizzate duro per una migliore efficienza ed una superiore durata nel tempo. La grafica è realizzata al laser.

    Extralite OctaOne 104 mm BCD Monoring

    La dentatura "fasata" alterna denti più stretti a denti più larghi in modo tale da accoppiarsi in maniera perfetta alle maglie della catena rendendo così l'utilizzo del guidacatena opzionale e non indispensabile.

    Extralite OctaOne 104 mm BCD Monoring

    Le fresature superaccurate consentono anche di relaizzare un profilo dei denti smussato in maniera tale da agevolare l'utilizzo con i pignoni più esterni ovvero il primo e l'ultimo della cassetta pignoni che sono notoriamente i più critici ma spesso anche i più utilizzati.

    Extralite OctaOne 104 mm BCD Monoring

    Le OctaOne inglobano nella loro struttura le bussole femmine che permettono di centrare più facilmente la corona sullo spyder delle pedivelle mantenendo un corretto spessore per ottimizzare la linea catena e con l'ulteriore vantaggio di essere fissate mediante l'utilizzo di sole 4 bussole maschio standard contribuendo così a ridurre il peso complessivo.

    Extralite OctaOne 104 mm BCD Monoring

    Le corone OctaOne sono disponibili in colore nero nelle seguenti dentature :

    • 30T - 28.5 grams

    • 32T - 29.5 grams

    • 34T - 32.0 grams

    • 36T - 34.0 grams 

    Si tratta di pesi record che le pongono ai vertici della categoria contribuendo a rendere ancora più vantaggioso in termini di peso il sistema monocorona senza però incorrere in particolari limitazioni, infatti la struttura pur essendo leggera è molto rigida per via della sezione a "c" e l'utilizzo di materiali, lavorazioni e finiture al top, consente una durata nel tempo anche superiore alla media.

    Le corone OctaOne sono 100% Made in Italy.
