Heidenau Inner Tube 10 D – 41.5G/70° 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 — a wider-profile range for scooters than the 10 C.

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 an angled 41.5G/70° valve with an extended stem — useful when a standard-length valve doesn't reach through a deep rim or decorative cap.

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 and angle 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.
