Having waited a while before placing the order then another few weeks until the order finally arrived, I now have new wheels for my mountain bike – new, lighter, slicker, and tubeless too. This last point makes the biggest difference from anything I have previously owned, which all had inner tubes; I have had to learn how to handle the tubeless system almost from the start as one of the tyres wasn’t holding air very well, it was fine for the first ride but after that it lost all of its air over a period of a few days… when I went to get the bike out for my next ride I found it completely flat, I pumped it up and thought the sealant would fill any holes, which it seemed to at the time, but during the ride I started to lose pressure until it wasn’t possible to pump it up fast enough to just maintain pressure, something had gone very wrong. I had to use the emergency inner tube and by this time it was late afternoon, time to head straight home and sort out the mess later. In my haste I forgot to take the valve with me so dropped into the local bike shop to buy new valves and a roll of rim tape.
Later was today, almost a week later in fact. I took the tyre off and gave it a good clean with hot soapy water (just normal liquid hand soap) to remove the sealant, I did the same with the wheel and inspected the rim tape – it had lifted where the join was and also the tape was not the correct width for this wheel, it was too narrow so not seated correctly, in places it was barely covering the spoke holes and was not trapped at the rim by the tyre as it should be, little wonder then that there were massive air leaks, I’m surprised it managed to seal at all.
