Inner tube 8x2 valve 90x45°

Size

8x2 inner tube. This size is also designated 200x50 by some manufacturers: 8 inch outer diameter, 2 inches wide. It fits the E-Road Ciwo and machines with the same fitment.

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

90x45° valve

The valve is angled at 90 degrees on its first segment and 45 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 90x45° valve does not replace a straight valve, nor a 45x45°, nor a 90x90°. 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.
