The IRC Comp is a new competition model in the Siren series and has been developed with an aramid bead with an emphasis on weight reduction. These two are the 20 x 1-1/8th & 1-3/8th versions suited for your youngest racers and won't break the bank when they chuck a few skids at the finish line.

Features

Aramid bead for lower weight. IRC developed the Comp with an aramid bead and an emphasis on cutting grams, down to 258g in the narrowest size.
Competition model Siren. The Comp is the racing version in IRC's Siren series, built for riders lining up at the gate.
Three narrow sizes. Available in 20 x 1.5, 20 x 1.75 and 20 x 1.9, so you can match the width to your rim.
Suits the youngest racers. The narrow widths are aimed at junior racers, and they will survive a few skids at the finish line.
70 to 100 psi. Every size runs the same pressure range, so you can set it firm for a smooth track or back it off.
