Q-Tubes Road Tube

We picked up the Q-Tubes to fit larger volume road tires and CX tires. They will generally fit road tires above 25mm and cross or commuting tires up to 45mm depending on which tube you select. These standard tubes are not of the ultra light variety, so you can expect durability and reliability in the field. The threaded valve stem features a removable core, so they are compatible with a variety of valve extenders and you can add sealant via an injector if you wish.

We offer this tube in valve length and tube diameter options. Chose the between 32mm and 48mm valve lengths depending on your rim depth. When in doubt, just go with the 48mm. It fits almost any standard or semi-standard rim depth. The 28mm-32mm diameter fits most larger road and cross tires while the monster 35mm-48mm diameter will fit the largest of 700c tires.
