§ 02 / About this part
What it is
The MICHELIN TUBE CH.21 TRIAL / VALVE TR-4, tubes. Stocked by Iron Offroad, the UK MX hard parts specialist.
This specific tube is designed for the unique demands of trial bikes. It sits inside your front tyre and allows for the extreme flexibility needed at very low pressures. The rubber compound is thinner and more pliable than a standard motocross tube to ensure maximum footprint and grip on technical sections. It fits standard 21-inch front trial rims. Replace this if you notice any air seepage or after a heavy impact that might have pinched the carcass. Ensure your rim lock is correctly seated to prevent the valve from tearing under low-pressure torque.

§ 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.
