Heidenau Inner Tube 19 B – 34G Valve

Heidenau 19B fits the 2.00 size for 19-inch rims — a narrow size for lighter mopeds and scooters.

The wall here is thinner than in the Cross class — 1.5–2.0mm: enough for everyday road riding.

Material and durability

Heidenau 19B is made from natural rubber: the material resists mechanical stress better than synthetic compounds and holds elasticity for longer. The trade-off: it loses pressure slightly faster than synthetic rubber, so check pressure with a gauge from time to time.

Valve and fitment

Heidenau 19B comes with a standard-length, straight 34G valve — a simple, reliable choice where no bend angle or extra stem length is needed.

Application

Heidenau 19B suits mopeds and scooters with a narrow 19-inch rim under normal road conditions. Natural rubber retains elasticity better at low temperatures in Kazakhstan's winter, but ages faster than some synthetic materials during prolonged use in summer heat.

Fitting recommendation

When fitting Heidenau 19B, check the length of the original valve and use a new rim tape of the correct size. Pinching the tube with tyre levers remains one of the most common causes of premature tube failure.
