Tufo S3 Lite 215g Tubular Road Bicycle Tire 700 x 21

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.
