Needed inner tubes and after some good reviews I went for these ones. They're extremely light (and expensive) and thought they'd be worth the money as reducing weight on wheels is better. Used them for first time last Thursday night ride at Epping Forest (fine, no probs) and planning to use them for today's race.
Anyway, first problem came when unscrewing the pump from valve, that also unscrewed the piece inside the main body valve (not the captive nut) releasing all the air. That was quite annoying and happened twice.
Today Sunday I was changing tyres for the race. It happened again. Then I tightened it with an adjustable spanner and hold base of valve with one hand very tight to allow tightening a little bit. Well, it worked (never unscrewed) but now air leaks from somewhere at the base of the valve (didn't have time to check properly as I was running late).
Had to get a spare one an leave home quickly. During the race I had a puncture on rear tyre (the one with Supersonics) and I think I've wasted some cash.
Going tubeless seems expensive and messy ouuch!!
Any recommendation?
