The tires are 26" if memory serves, under the seat it says 19.5". It seems to fit me well but then again i've never been "fitted" for a bike.

To the next post, I've been looking a little on craigslist but i don't know exactly what i'm looking for aside from name brands like Trek and Giant.

I'm also not opposed to fixing the one i have if i knew how. I'm not at all afraid to take it apart, worst case scenario i screw up a free bike. Like stated the 3 speed front gear is not working at all. I push the lever and the cable doesn't even budge. I'm assuming something internally in the shifter? As for the the 7 speed rear gear set, the bike is currently in 7th. If i push the lever to down shift it will go into 6th and the indicator will show 6th gear. However as soon as i release the lever, the indicator goes back to 6th and the bike shifts itself back to 7th gear. Not sure if the derailleur is just worn out and will no longer hold its place or if its in the internals of the shifter.

New bike or not i'd at least want to fix this so i can resell it for a little cash to put toward a better bike.

You mentioned the feel of a fast road bike. Aside from the tires, why is a road bike better for "the road". I would assume they would be relatively similar otherwise? If i am wrong feel free to inform me otherwise, really just still new to this.

I certainly think a trip to the LBS is in order. There is one that is actually not far off of my commute, i should probably stop in there on my way home one day and have them look the bike over and perhaps talk to them about what i need in a bike and then look at used stuff from there. First priority i think is fixing what i have.

Thank you all for your responses.
