Would something like this work with a separate bottom bracket, crank, and front derailleur adapter? If so what would be a good cheap 2x crank and bottom backet for it? I don't mind buying parts here and there, or mixing matching parts as long as they work. I already have a 11 speed Shimano cassette that came with the trainer. And because this is just for the trainer I don't need brakes or back tire.

Also I know it is a junk bike, but looking where I live used is $600 plus for a 10 or 11 speed. I want to save up later and buy a good road bike in the $2k range so I don't want to spend money on a used bike.

Thanks again for any help.
