This defies logic and therefore must be supernatural...... I ride a Spesh Tricross during the winter months and have till now run on 23's but of late due to the wet and muddy roads at this time of year I decided to change to 32's with a bit of tread. This was moved forward by two punctures in a week which I thought was just a run of bad luck.. However on changing the tube on the first puncture everything was ok until the following morning when the tyre was flat again. I checked the tube - fine, i checked the tyre-fine, I checked the rim tape and wheel-fine. Hmm, pumped up and off on a ride. Fine. In the morning - flat. Changed tube, checked everything, tyre up and at pressure all day. In the morning-flat. Changed tyre and tube, checked rims, tape and wheel - fine. Pumped up - fine all day, same pressure at 8pm, morning- flat. Today exactly the same !!!!! what is going on !!!!! the wheel is kept in a locked garage and no one else has the key !!!
