Since taking up cycling again in November last year (after a very long break) I've ridden over 2500km mostly commuting on both a mountain bike and a road bike, but in the last 4 months or so riding 60-70km on weekends. The amazing part is that in all this time I've only had 1 flat tyre and that was when I first started out on my mountain bike. Since getting my road bike I've done about 2000km had no flat. This does seem quite low, especially for London roads... Back in the day I remember getting a flat at least every 500km or so...maybe my luck has changed.
I think I might be tempting fate by posting this, but I am touching wood.
On average, how often do you get a flat?
