Q&A
The largeset sprocketss are divided into sets of three and are mounted on a new aluminium carrier. Thanks to this, rigidity increases 180% and the individual sprockets are 70% more resistant to torsion.
The teeth have been designed to optimize the speed and fluidity of shifting. This form reduces stress on the chain which ascends more easily onto the higher diameter sprockets
Three largest sprockets are tiatium and the remaining eight are steel with a nickel-chrome surface treatment
