I just bought a Trek 2300. I'm pretty sure it's a 92 (photo below). It seems like a really cool bike! But - I took it out for a 10 mile first ride and managed to get a flat the first time out. LBS where I bought it (used) said it appeared to have been caused by a thorn.
They suggested tougher tires (they're a Trek shop, so they recommend Bonnies, natch). A friend of mine suggested Panaracers - and also switching from the 700X23 tires currently on the bike to either 700X25, or better yet he said 700X28 for durability and flat protection. Only trouble is, I don't know whether that frame will accommodate 700X28 tires.
Does anyone here know?
