Scirocco C17 Clincher Wheelset The Scirocco C17 features the new wider profile rim design, giving better profile to the tyre, maximising Grip, comfort and aerodynamic benefits.  The 35mm deep alloy rim which gives the perfect balance of aero performance and lightweight, making this a perfect wheelset for any road conditions. All of this combined with Campagnolo's unique G3 spoke pattern ensures you have one of the stiffest and lightest wheelsets available. The Mega-G3 Spoke pattern is a type of spoke assembly that improves energy transfer between the hub, which reduces stress on the right-hand side which in turn increases the rigidity of the wheel. This is achieved by having twice as many spokes as the left hand side. State of the art technology and great performance from the very first mile. Assembly The Scirocco 35 C17 Wheel is entirely hand built by a specialised Campagnolo technician and is checked in every tiny detail with electronic tools. This ensures that every wheel conforms to the high standards that Campagnolo pride themselves and will have unbeatable reliability.
