Explorer Spoked Wheel Valves

To cut a long story short. The valve in my Explorers spoked wheel sprang a leak over the weekend. I removed the wheel and took it to a local bike tyre dealer to be replaced. Dealer removed the old valve only to find that it was an odd size. They phoned around for an hour to see if they could find a valve somewhere else. No luck so handed me the wheel back and suggested I took it to a Triumph dealer which I did. Turns out even the Triumph dealer had to order one specially. Nearly 5 days later and still no valve. Once I've got this sorted I'm going to get a couple of spares to go under the seat. Anyone else had this problem?

 

I believe it's only an issue with the spoked wheel because the way in which it is made giving a smaller area for the valve to sit in.

 

These spoked wheels are a special design which allows them to be tubeless. The spokes don't go through the rim but into a secondary rim attached to the main rim. You may say why have spoked wheels and the answer is they are stronger. Not that I use the bike off road. This modEl just happens to come with this type of wheel.

 

Only on the Explorer. Even then it wasn't standard. Triumph ran some specials back in 2015 which was a XR upgraded to an XRT with spokes. Apparently that is what mine is. Un-aware of that when I bought it 4month's ago!
