IRC has been making some impressive road tubeless tires for a while, and now the one of their lightest is growing to include a new 25mm and 28mm width.
The 25mm should come in at 300g, and the 28mm just a bit higher. They’ll head to the U.S. in June packaged with Stan’s NoTubes sealant and available through them first. About a month later they’ll start shipping by themselves through J&B and BTI.
While the name implies lightweight road, the 28 will actually get a quasi-file tread similar to their Serac CX Sand cyclocross tire we spotted at Taipei Show. That makes it their new gravel tire.
