, old hardtail Treks are pretty common for the commuters. I got mine for $40...
Definitely the direction I'm thinking of going in for my main utility/commuter/do-all bike. Question though, what should I be looking for when I go to check out these old MTB frames? I know they should be steel framed, chromyl if possible without any cracks. I'm going to be replacing the tires anyways, so probably no problems there. Anything in particular you think I should keep an eye out for? And besides changing out the tires, what else must be done to hardtail MTB to make them suitable for commuting?
Oh, and another newbie question: What sized tires will these older MTB hardtails use? 26 in? And does it make a really big difference if the wheels are 700c or 26 in?
