Speedsix Air Ultralight 45 Wheelset - Shimano

The Speedsix Air Ultralight 45 wheelset has been redefined to establish the range and provide an advantage for the most demanding cyclists. The Air Ultralight represents the very definition of lightness without sacrificing the rigidity essential for unparalleled performance on the road.Each profile has been designed to meet the specific demands of different riding styles; from steep mountain ascents to flat stretches without losing cadence in pedalling, you will find the perfect profile for every challenge on the road.For the carbon rim, we continue to work with Ultralight Carbon Nano-Tech (UCNT), known for being a very lightweight carbon and for its construction in multiple layers, combined with HiTech Nano-resins, which provide the necessary rigidity while offering the extra lightness that characterises these rims. The internal width of these rims is 21mm, allowing for the mounting of tyres ranging from 25mm to 30mm.
