Description

The IRC Comp is a new competition model in the Siren series and was 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. The aramid bead is where the weight saving comes from, so the wheel spins up faster out of the gate.
Two junior sizes. Offered in 20 x 1-1/8 inch and 20 x 1-3/8 inch, covering the youngest racers through to the smaller Expert bikes.
178g in 1-1/8 inch. The narrow version weighs 178g and runs to 70psi, which is about as light as a race tyre gets at this size.
259g in 1-3/8 inch. The wider version weighs 259g and takes up to 90psi, so you get more footprint without much extra weight.
Competition model in the Siren series. IRC developed the Comp as the race focused version of the Siren, with weight reduction as the priority.
