Tyre Type:

The 303 S Tubeless Disc is approved for use with tubeless and tubeless ready tyres only, due to the hookless rims. Please make sure that the tyre manufacturer's approval is given for hookless rims. An inner tube can be used with a tubeless/tubeless-ready tyre which is compatible with hookless rims. Follow the installation recommendations of the tyre manufacturer.

Features:

• new Zipp graphics for a speedy look
• fastest with 28 mm tyres, but also suitable for wide Gravel tyres
• wide rims allow lower tyre pressure, especially with tubeless tyres
• larger contact surface for more grip and therefore more safety in curves, descents and when handling on wet roads
• lower tyre pressures and a larger volume ensure a more comfortable ride and less vibration
• significant watt savings when using wider tyres at lower pressures
• wide hookless rims create a seamless transition to the tyre and reduce air resistance
• aluminium axles
