a few years ago I bought a cheapie bike. That bike served it's purpose (gave me the chance to see that I love riding), but isn't the quality bike I'd like. Unfortunately I was hit by a delivery truck about a year after I bought the bike, bent rear wheel and frame (along with two knee surgeries), but the rest of the components are in good shape.

We're only talking Shimano 105 components, but I've looked for a decent bike with good components and I can't find anything in my price range. Figured it might be cheaper for me to buy a frame only and move my old components over.

How difficult is it to take components from one frame and move them to another?
