Only ridden on the tube on one short ride so far. Seems to be ok, pleased at this early stage of usage.
I have been looking for a 26" Presta for a while and I came across these VeloChampion ones and they're ideal. Ive fitted both tyres with them and not had any problems with them. I found a lot of 26" schrader tubes, but not presta and still have a spare to carry with me on rides now. :)
