Heidenau Inner Tube 10 D – 34G SV Valve

Heidenau 10D fits the 3.00, 3.50, 90/100, 90/90, 100/90, 100/80, 110/80 size range for 10-inch rims — the same range as the angled-valve 10D, but with a straight, long valve.

The wall here is thinner than in the Cross class — 1.5–2.0mm: enough for a scooter.

Material and durability

Heidenau 10D is made from natural rubber: the material resists mechanical stress better than synthetic compounds and retains high elasticity even after prolonged use. 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 10D comes with a straight, long-stem 34G SV valve — useful when the standard length doesn't reach through a deep rim or decorative cap, but no bend angle is needed.

Application

Heidenau 10D suits scooters with a 10-inch rim. 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 10D, 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.
