would you recommend. I measured the rim on my Trek 7.2FX and I can put a 700x25 on my bike - I would like to try a 25 but do not want to spend a whole lot of money on a set of tires in case I don't like it and decide not to use them. I ride only on paved surfaces but most of them have lots of patches and small potholes. Anyone know a decent tire that won't flat easily and won't break the bank either?
