COMPATIBILITY NOTE FOR SCHWALBE TUBE ITEM 20 ‘EXTRA LIGHT‘

Modern tires and rims are getting wider. This has a particularly positive effect on the riding experience and performance. The use of wider rims has the effect of increasing the cross-section of the tire and thus its internal volume. This can result in the tube used being overstretched.

For this reason, Schwalbe tubes of the group Item 20 ‘Extralight‘ may only be used with rims with a maximum inner rim width of 19mm (19C). Prerequisite to this ist he adherence to the approved dimensions according to the labelling (18/25-622/630).


! ! If this is not observed, there is a risk that the inner tube in the tire will be overstretched and no longer have sufficient wall thickness. The tube could burst as a consequence and cause the cyclist to fall while riding.
