      I bought the inner tube but was a bit disappointed had when I got home I didn't have the correct fitting on the pump to inflate the tyre.

      Already bought one of these when fitting a new tyre to my partners bike, bought a second to fit when the requested tyre is in stock.
      First time tried these but you don't know until you try them, so far no problems with the first one I fitted, despite a couple hundred miles so far on thorn covered tracks, I think the ungraded tyre helps to.
    • Highly recommended tube.

      I've had these tubes in for around 4 months now, had no trouble fitting and haven't noticed the extra weight as some people suggested I would.
      I am really enjoying going out with the club and not being the one with the punctures. I'm out several times a week over some rough terrain and I know there are several thorns that have gone in them but they are still fully inflated so very happy.
      Some say the downfall of these tube are that if they deflate and you need to repair you will probably find several punctures and you would have to repair them all before re inflating. My answer to this, if I found the tube had multiple punctures that needed repairing, for the sake of £3.99 I would just replace with a new one. If every set lasts over 4 months I'm more than happy with that.
      being puncture free when out with the club!
      None as yet.
