Inner tube 200x50 rim 94 mm valve 30x90°

Size

200x50 inner tube, also designated 8x2, for a 94 mm rim. This size fits the Kaabo Skywalker and machines with the same fitment. The rubber adapts to a range of widths around 50 mm.

A small rim diameter

94 mm is a reduced rim diameter for this tyre size: the sidewall is therefore taller than on a standard rim. A tube made for a larger rim will be too short and will not seat correctly.

Check the inner diameter of the original tube before ordering. The outer size alone is not enough.

30x90° valve

The valve is angled at 30 degrees on its first segment and 90 degrees on the second. This angle is dictated by the rim and mudguard geometry: it gives access to the valve with an inflator head where a straight valve would be unreachable.

A 30x90° valve does not replace a straight valve, nor a 0x90°. 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.
