Campagnolo Shamal Ultra C17 Wheelset - 2 Way FitThe Shamal wheelset has been at the forefront of innovation since its inception over 20 years ago. It was developed as the very first complete wheelset with each component in its build being specifically designed as a complete unit to ensure unparalleled efficiency and performance The new Shamal C17 was developed specifically to increase compatibility with 25 and 28mm tyres that are becoming increasingly popular due to their improved aerodynamics and reduced rolling resistance The new C17 also allows for a more surefooted grip on the road in addition to increased comfort while increasing rigidity and thus reactivity at the same time thanks to its wider stance and optimised material usage They feature a carbon fibre hub body with extra smooth USB bearings to make them as efficient as possible. The hubs for this newly designed wheel are differentiated between front and rear in order to optimise weight savings while considering structural and performance necessities that change with the individual roles of the two wheels. The 16 aerodynamic anodised aluminium spokes on the front wheel are laced radially while the 21 spokes of the rear wheel are grouped in the Mega G3 pattern, famous not only for its fantastic performance but also for its innovative design. A new adjusting lock ring with microsetting has trickled down to this new C17 version from the Bora family, further highlighting the Shamal’s status as a top tier race wheel The 2-way fit system allows you to fit either a tubeless tyre or a classic clincher for maximum adaptability Features: New wider rim profile that has been optimised for 25 and 28mm tyres USB Ceramic bearings Microadjust allows you to set preload on the bearings Oversized aerodynamic spokes Differentiated rim height G3 Spoke pattern MoMag™ technology Oversized drive side flange Weight: 1505gBuy Campagnolo Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
