HEIDENAU Tube 21D CR

Heavy-duty bike tube by HEIDENAU, specifically manufactured for off-road motorcycles.

All HEIDENAU tubes are exclusively made of tough and highly resistant natural rubber which has been proved to be much more expansible than the commonly used synthetic materials (e. g. butyl). Therefore, one HEIDENAU tube fits for various different tyre sizes (see below).
