Inner tube 14x2.50 with straight valve

Size

14x2.50 inner tube. This size fits the Dualtron City and machines with the same fitment. The rubber adapts to a range of widths around 2.50 inches.

Check the inner diameter of the original tube before ordering — the outer size alone is not enough to guarantee the fit.

Straight valve

The valve is perpendicular to the rim, with no bend. This is the simplest and most common fitment: it works whenever nothing obstructs access to the valve — no brake disc or motor facing it, and enough clearance under the mudguard.

On rims where access is restricted, an angled valve is required. Check the angle of the original tube before ordering: this is the leading cause of error on this product family.

Fitting

Sold individually. Inflate the tube slightly before inserting it into the tyre to avoid folds, and make sure it is not pinched between the bead and the rim before bringing it up to pressure.
