Question: what are folding bike tyres?
Answer: A folding tire is a special version of the clincher tire. The wire bundle is replaced by a bundle of Kevlar strands. This enables the tire to be folded up and depending on the tire size, makes it approx. 50-90 g lighter. ... In a tubular tire, also referred to as Tubular or Collé, the tube is sewn directly into the tire.
