VITTORIA Zaffiro V rigid/non-folding tyre, 28×700

Zaffiro non-folding clincher tyres are ideal for recreational riders and training. Extremely puncture-resistant.

Casing density is measured in TPI – “threads per inch”. The closest approximation is “threads per square centimetre”: the density of threads in the tyre per unit area. The casing is the heart of the tyre/tubular and is made from different rubber and thread compounds, with threads that may be made of nylon, cotton, Kevlar or Corespun.

Standard road tyres/tubulars are usually made with 24 to 55 TPI (thread density). Vittoria tyres and tubulars feature casing constructions ranging from 25 to 320 TPI (thread density). Serious riders and racers looking for the best tyre most often choose tyres with a higher TPI.
