Repeated front wheel puncture I've just had my 3rd front wheel puncture in about 4 weeks (doing around 80 miles per week).  Since the first puncture, the tube and rim tape has been completely replaced, but these seem to have not solved the problem.  

I'm riding a road bike which is about 8 years old (but has only probably seen a years worth of proper weekly usage) on a mostly road based route through London, with a 5ish mile stretch on a canal towpath.  Thanks!

Puncture was on the inner surface of the tube (ie facing the rim.)
So it turned out that my tires were really old and rubbish, and had a few bits of gravel, glass etc embedded in them which were puncturing the new tubes every time I changed them.  I bought some new tires (puncture resistant ones) and I haven't had an issue since.  Thanks for all your advice everyone!
