I've done a diy tubeless conversion on my poles and love it. So the pole hose now lives on the hose reel and I'm wanting a slimmer permanent connection to the microbore. I use 6mm microbore and standard yellow pole hose. I got what I thought I needed, a straight barbed reducer, 6mm to 5mm but it's really leaky and can pull apart quite easily. I'd rather not have o rings or jubilee clips if possible. I guess I bought the wrong size, will an extra mm on each side be enough to sort it? What does everyone ride use for their tubeless setups?
