The new version of Shamal" Ultra" wheels is a concentrate of technology: 2-Way Fit" and USB".
2-Way Fit" makes it possible to mount both tubeless or standard clincher tires on the same wheels, giving riders the possibility of making the best of either solution depending on circumstances.
USB" means superior smoothness. The renowned Campagnolo hubs are now fitted with ceramic balls of the highest quality that further improve their smoothness of operation. Starting this year the Titanium finish has been replaced by an aggressive Black finish.
