§ 02 / About this part
What it is
The MICHELIN TUBE CH.21 MDR / VALVE TR-4, tubes. Stocked by Iron Offroad, the UK MX hard parts specialist.
This heavy-duty tube provides reliable puncture resistance for demanding terrain. It sits inside your front tyre to maintain pressure through rock gardens and hard landings. The TR-4 valve stem is a standard fitment for most off-road rims. Replace your tube whenever you fit a new tyre to avoid fatigue-related failures. It is a vital component for enduro and MX riders who need consistent performance in varied track conditions. Always use a rim tape to protect the rubber from spoke heads.

§ 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.
