Im looking for a new frame for my old bike. the frame i have now is a 18". yes im awear its a trek 4300, but ive swapped out the rims, and the fork, now i just need a good frame under $200 to make it a really good backup bike. heres a pic of my bakup bike, any reccomendations for a new frame? (if so id appreciate a link of where i cud buy it cuz my lbs like all others charges more then the internet)
