Ok well again keep an open mind and also you will wanna keep in mind the material you want your bike to be made of. Carbon is great but then again bits you up and you might not want that if your using biking as a rest; however aluminium is great but you can go lighter than that. For cheaper but high quality stuff you might wanna look into light steel bikes like Lemond has some that are pretty cool. Well check them out at http://www.lemondbikes.com/home.shtml. Hope this helps!
