CHAIN CHORUS 12 VELOCITY
In order to ensure impeccable and reliable functionality even with increased pignoni parcels,
the changed accuracy has been achieved through the design of a 12-speed chain,
that required a lot of research and development energies to make it just as reliable and durable
compared to a 11-speed chain, despite the reduction in thickness compared to the latter.
The new 12-speed Chorus group benefits from a new Chorus 12 chain that ensures the same
reliability and the same performance as that of the Super Record level, coming to weigh only 241 grams per 110 jerseys.
