I'm very interested in gettting one got about 800$ to spend on a new bike and I have been looking around for what is a good investment, quality wise.

my questions are as follows:

Where can i find a frame set I ride a old tommaso conversion 56cm atm but I hear BK run a little big should i stick with 56 or go to 54?

What sort of price am i looking at for a frame set, i have seen or heard them going for anywhere from $450 - 850.

with the BK fork and a 700c wheel is there clearance for bar spins?

and if you have any suggestions as to an alternate frame Id appreciate it. I have been riding my Conversion for about 5 years now I just dont really keep up with whats new cool so much as just riding a lot, so im a bit uninformed

Thanks guys and girls
