Mezzo is currently living in a corner of the living room. The other day I hear a hissing noise consistent with air at high pressure escaping from a tyre. The front tyre went flat with no apparent reason, taking the tyre and tube of revealed that the tube had burst because it had pressed into the spoke holes. The rim tape is the thinnest and softest material I have seen used for the job so I replaced with a good quality fabric tape. It was fortunate that I was not riding at the time so I recommend anyone who has a Mezzo to check the rim tape and replace it if it looks suspect.
