Tufo C S33 Pro Tubular Folding Road Tyre

The Tufo C S33 Pro is a training tubular clincher tyre for all around use with higher inflation pressure. The fine tread pattern contributes to low rolling resistance and good riding quality. The carcass consists of two layers of rubber cord composite with reverse bearing cord orientation in each layer, joined with natural rubber matrix strengthened with silica.

When inflated, the tubular clincher, in the same way as a tubular, is pressed towards the rim. Simultaneously, the bead blocks of the profiled rubber band spread out embedding on the rim shoulders and eliminating any rotation of the tubular clincher against the rim as well as possibility of the tubular clincher unseating.

The bottom profiled bead band does not function only as a filling in the area between the rim and the tubular clincher but also plays an active role. As the tubular clincher is inflated, the band sides literally “bite” into the rim shoulders.

Key Features:

• Carbon black tread compound
• Fine tread pattern for low rolling resistance
• The inside airtight layer is made of a special butyl-rubber compound. Very low air permeability of this layer means long intervals between tyre inflations. Solid bond between the airtight layer and the tyre carcass means lower rolling resistance.
• The bead profile reinforcement of tubular clincher tyres provides easy tyre installation and prevents the tyre from unseating in extreme situations.
• The bead profile itself copies the shape of the rim and after inflation provides a perfect joint between them. Also protects the rim lips from damage.
