The Tufo C S33 Pro is an affordable training tubular clincher tire for all-round use with high inflation pressure up to 12 bar (175 psi). Fine tread pattern contributes to low rolling resistance and good riding quality. With 60 TPI sidewall carcass and 90 TPI under the tread.
When inflated, the tubular clincher is pressed towards the rim in the same manner as a tubular tire. Simultaneously, the bead blocks of the profiled rubber band spread out embedding on the rim shoulders and eliminating any rotation of the tire against the rim as well as the possibility of the tire unseating. There is no pressure applied to the rim walls. This tire fits only hook edge rims with an inner width of 13-15mm!
