Veloflex ProTour RACE Tubular Tire - 25-622 | gum

Tubular with a very soft 350 TPI (Threads Per Inch) Corespun casing for top performance. The tread is made of a compound with natural rubber and SiO2 that improves grip and road holding. 
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 Veloflex 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: that is the pride of Veloflex.

Advanced technology

Veloflex combines their artisan vocation with the latest technology and unique materials to obtain our top-quality products.

Casing

Soft and flexible 350 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 tire, offering excellent grip and exceptional low rolling resistance.
