Tubular tyres are tyres which, unlike standard clincher tyres, are not clamped into the rim but are completely closed and glued to the rim. Only in the tubular tire itself is now the actual tube, which thus withstands a much higher pressure of up to 15 bar, which is the real reason for a tubular tire. In addition, this type of tire is lighter, as well as the rim designed for tubular tires, since no rim flanges are needed to attach them.
Manufacturers such as Hunt Bike Wheels and Zipp offer special carbon wheels for use with tubular tires.
