The very first Campagnolo branded wheelset developed specifically for disc brake equipped road bikes comes at a time where the market has plenty of solutions for road disc wheelsets but lacks solutions that offer a level of performance, reliability, safety and integrity that has always been associated with Campagnolo wheels.The Zonda disc brake wheelset is not only more reactive when compared to the rim brake version but it is also 25g lighter than its closest competitor. The new C17 rim ensures a better rim/tyre interface and improved performance especially when using 25 and 28mm tyres.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.Adding more technology to the wheel while increasing its performance, lowering its weight and ensuring that same Campagnolo reliability cyclists have come to expect, a wheelset that should be at the top of the list for any athlete in the market for a serious upgrade.** Features:*** RDB (Rim Dynamic Balance) exclusive technology engineered into the rims, assures perfect balance even at high speeds* Asymmetric rim profile, 26mm to 28mm* Disc Fitment: AFS/Centre-Lock (Lockring included) / 6 Bolt (Bolts not included)* Axle Fitment: 9mm Quick Release Levers (QR) * **(Front hub can be converted to 110x12mm Bolt-Thru by simply removing the pre-installed axle end plugs)*** MOMAG: the external rim profile is free of holes, so the structural integrity of the wheel is increased and there is no need for rim tape* Adjusting lockring with micro setting, for accurate adjustment of the hub* Aluminium hub & aluminium axle for low weight and high stiffness* Oversized flange for increased torsional stiffness* Aerodynamic spokes with black anodized self-locking nipples* Modified versions of the famous Mega G3 Spoke pattern on both the front and rear wheel, for equal spoke tension, stiffness and increased braking torque resistance* Weight: 1675g Clincher, (CA) for Campagnolo, (SH) for Shimano**Assembly**The Zonda C17 Disc Brake Wheel is entirely hand built by a specialised Campagnolo technician and is checked in every tiny detail with electronic tools.
