I know it may not seem like a lot compared to what some of you guys ride, but I did my first 10 mile ride this morning. What a great feeling. I should smash 100 miles for the month and end up closer to 150. That first ride when I though my legs were going to burst into flames at 1.5 miles I would have never thought I would be able to do it in less than a month, but I did.
All that got me to thinking. If I am going to keep all this road riding up maybe I should get some road tires for the old mountain bike. I would like to get an extra set of rims so I can keep my knobby tires for trail riding. Looking at what that will cost I could probably get a used road bike off of Craigslist. So I'm not sure what to do. I need to stay low budget say under $500 or so, most of my fun money goes to things I can do with my 3 year old.
Would a good bike shop tell me what size bike I need to look for even if I'm not buying it from them? What are some things I should look out for when looking at a used bike? I know next to nothing about bikes so any help would be appreciated, even if it is to tell me my expectations and budget are unrealistic.
