Now I know there's plenty of variables to consider here, but I wanted to see if you guys could help me out with the little bit of information I have at the moment.
someone has an old bridgestone mountain bike on craigslist, and it doesn't sound like he knows a ton about it, so the only real measurement I've gotten out of him so far is that it's 29in from the ground to the bottom of the "cross bar", which I'm assuming is the top tube. If I was at home I would measure up some of my bikes and see what it compares to, but I'm at work, and have no tape measure or anything to really compair much right now. What size do you think this bike may be? I'm 5'8, I think my inseam is about 30 inches. I don't mind a bike that's a little big as I'll probably use it for commuting, and not actually offroad. I can survive a top tube if it's a little high because the mountain bike/commuter I used all winter was an old cannondale with that monster 13" bottom bracket, so it was super high, and I don't have to put my feet down much anyway. There's no picture of it. I know I can always stand over it and say no if it doesn't fit, but buyers on craigslist are always so flakey, and I don't wanna lead this guy on if it's not gonna work out.
So anyone think they can help me guess what size frame this is with a "29" from the ground to the bottom of the cross bar" measurement? -

I just looked up the BS mtn bikes. According to what he's telling you, the measurement from floor to bottom of toptube is 29" which means the stand-over heighth will be 30". Given that, the BS mtn bikes with a 48cm frame have a stand-over heighth of 76.4cm. I checked that with the MB-1 and MB-2.
30"x 2.54 = 76.2cm so the frame is definately a 48cm or 19". -

You can go check it out for size, and if it doesn't fit, you can help the seller out by doing an inventory/assessment of the bike - size, components, condition etc. If nothing else, you're passing on your knowledge to someone who doesn't already have it. I've often done this with less-knowledgeable Craigslist sellers; even if I don't buy their item, they have more detail to give to future prospective buyers. Usually, they appreciate the help.
And if you discover that they're selling some treasure for wildly less than it's worth because of their ignorance, and you clue them in, they really appreciate that...
