ANVELOPA TUBULAR-CLICNHER TUFO C HI-COMPOSITE CARBON 28 25mm

Application of composite puncture proof ply and high composite carbon tread compound made possible to use thinner tread and still maintain high mileage. Thinner tread also lowers rolling resistance while the tyre is maintaining ideal shock absorption properties and high puncture resistance.

Construction

Unique patented construction. No extra investment in switching from clincher tyres to tubular clincher tyres. Riding properties are equal to those of tubular tyres.

- Low rolling resistance, low weight
- No need to use a rim tape nor glue
- The easiest and the fastest mounting from all the tyre types, no tools required
- Distinctly the safest behaviour in case of flats without effecting the rider's stability, can be ridden flat in case of emergency
- Can be used immediately after mounting

A - Tread - produced either with rubber compound of activated silica, silica or carbon black (specified for each model).

B - Protective rubber ply - located underneath the tread, indicates also tyre wear and higher possibility of punctures when showing through the tread (only in specified models).

C - Puncture proof ply - made of rubber cord composite strengthened with CRCA.

D - The carcass - plies are overlapped and joined underneath the thread, creating increased TPI (threads per inch) value and better tyre puncture resistance.

E - The carcass - consists of two layers of rubber cord composite with reverse bearing cord orientation in each layer, joined and strengthened with CRCA. The carcass TPI varies from 60 to 210 for different tyre models.

F - 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.

G - The base tape - is made of cotton. It absorbs the glue evenly, resulting in optimal bond between the rim and the tyre.

H - The bead profile - reinforcement of tubular clincher tyres provides easy tyre installation and prevents the tyre from unseating in extreme situations.

BEFORE INFLATION	AFTER INFLATION

HOW DOES THE TUFO TUBULAR CLINCHER WORK?

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.
