https://youtu.be/3LAqubBLzYcThe Ghetto Tubeless a with split tube method, is that you use a smaller tube wide tube -- I was thinking of a 20" x 3" BMX bike tube, I have read of a couple of bike forums that is a optimal size, I dropped into a bike shop, ask and asked about obtaining a wide tube for 20" wheel or a 24" wheel and they didn't actually have any -- and when I explained what I was planning on doing, gee did they ever look at me strangely -- thought I was a bit weird. The reason the tube needs to be tight is that needs to be tight on the rim once the the tube has been split.
After leaving the bike shop with nothing, I had a bit of a brain wave, what about a motorbike tube, dropped into a motorbike shop, picked up a couple of 21"x 2.45/3.00 tubes.
What I liked about these tubes is the valve stem setup, it's particularly useful for this style of conversion, as the valve stem is threaded all the way.
Tube split and installed on my before the excess tube is trimmed trim.
The finished result.
What has surprised me on how easy the conversion actually was, and now I ride knowing a puncture from a thorn, or a nail should not stop me.
