§ 02 / About this part
What it is
The HEIDENAU INNER TUBE 21D CROSS / VALVE 34G, tubes. Stocked by Iron Offroad, the UK MX hard parts specialist.
Heidenau builds the 21D for riders who pinch tubes for fun. Cross-spec rubber takes a hit and keeps its shape, and the 34G angled valve sits clean against the rim lock without fouling the gauge. Run it up front on your MX, enduro or trail bike. Carry a spare in your bumbag if you're racing rocky enduros. Check the valve stem before every meeting and bin it the moment you see green corrosion creeping up the brass. Slot the valve through the rim first, then walk the bead on with two levers and plenty of soap.

§ 05 / About Iron Offroad
Iron Offroad
Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. Brands you'd find on a paddock workbench; pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere. Dirt & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
