Rated 4 out of 5 by Maxx75 Good stuff
4 stars only because I did on them tubes just 500km & still test them. At the moment all goes well & there wanst any not nice surprices. If will keep going that way for sure will be 5 Stars then.

It's a tube and does what it should. Feels quality rubber, holds pressure as butyl does and nothing to say negative about it. This is not a threaded valve (french style they call it) so if you want no marks on your rims, then get these.

Rated 4 out of 5 by FreeriderDave Good all round road tube
Good all rounder for the money. I briefly went cheap and was using Airwave tubes as their MTB tubes were not bad. However the Airwave tubes were not as good. Moving up to Michelin was notably better. I use these when I'm not using Latex Tubes.

Rated 3 out of 5 by Anonymous Leaks air like nobodies business
I got these tyres with the michelin pro 4 service course and all I can say is that these inner tubes leak air worse than halfords own brand. I pump them up one weekend, come back to them a few days later and the have lost about 40psi (started at 90psi). Apart from that they are what to expect from an inner tube

Rated 1 out of 5 by Anonymous Disappointed customer
I recently bought 2 of these inner tubes. I have had 5 of them before and had no real problems with them, they have obviously been punctured but through no fault of the inner tubes. The 2 I bought recently have been rubbish: the first, I pumped up to 100 bar at most before it exploded. I then put the other one on and pumped it to just over 100 bar, and this was fine for about a minute until it tore and went flat again. Very disappointed and am expecting a refund.
