Challenge Grifo Ultra Tubular Tyre - Black/Cream 700 x 33mm

Features

Handmade -Handmade tyres combine many attributes to create the most comfortable and low rolling resistance tyres.

Sealed Silk -Silk is a strong, soft, natural fiber casing that allow the casing and tire to perform at ultimate level.

Soft -Some of their tyres utilise a softer durometer tread rubber so the S also stands for Softer and more Supple. The softer S treads are especially used on track and cyclocross tyres.

Latex -Latex tubes are stronger, lighter, super supple, absord shock and conform to whatever objects impact it, reducing rolling resistance.

PPS -The Puncture Protection Strip is a special fabric placed between a tyre's tread and casing to increase resistance to punctures.
