Guaranteed specified weight. Specific use for road and stage races, triathlon.
Unique construction is based on the width of the tire tread. Wide tread overlaps
and protects the sidewall against damage. Underneath the tread is located a
puncture proof ply, coloured differently than the tread, serving also as a tread
wear indicator. Right under the puncture proof ply is a breaker consisting of
rubber cord composite with circumferential orientation. The breaker further
shields the tire against punctures and significantly contributes to lowering the
rolling resistance. Thread count underneath the tread - 305 TPI.
