ONZA tires is part of mountain biking history, no doubt about it. To honor days bygone, the brand brings old school looks back to mountain bikes: A selection of tire models are available in a skinwall flavour. As the sidewalls are not treated with butyl rubber, these tires have a very distinctive look and also weigh a little bit less than the blackwall edition. But most important, they put a smile on the faces of all those who have been into mountain biking ever since the 90ies, when the bar ends were long, the frame colours were loud and the sidewalls of tires were beige. Oldschool, you see?
