ProTour Gum Sidewall
Tubular with a very soft 320 TPI (Threads Per Inch) Corespun casing and an innovative compound that provides very low rolling resistance and great roadholding. It is equipped with an anti-puncture protection belt and an exclusive latex air chamber, for improved elasticity in every condition.
Handmade in Italy
All our tubulars are handmade through a process that consists of 35 rigorously artisanal steps, starting from the raw material and the different components (yarn, latex, rubber, glue, valves). Manual skill is key and no tubular is identical to another: this is our pride.
Advanced technology
We combine our artisan vocation with the latest technology and unique materials to obtain our top-quality products.
Casing
Soft and flexible 320 TPI (Threads Per Inch) Corespun casing, designed to ensure the lowest rolling resistance to the road bicycle tubular.
Internal polyester tape
It protects the internal air chamber of the tubular from the zig zag stitching that seals the casing.
Ultralight air chamber
A latex air chamber for greater elasticity and flexibility in every condition, i.e. the lowest rolling resistance on any road surface.
External cotton tape
It sticks the tubular to the rim to ensure flexibility and elasticity and to protect the casing from abrasion and the stroke of the rim nipples.
Puncture proof protection belt
An anti-puncture Calicot layer; its fabric, with a very thick texture, prevents any damage to the casing caused by sharp objects that may penetrate through.
Tread
Greatest road holding thanks to the new natural rubber and silica tire tread; with its RainDrop pattern it is the core of the clincher tire, offering excellent grip and exceptional low rolling resistance.
