Well I did take off the small chainring, but I just wanted to use just the big chainring and not have to shift in front, just the back. I'm used to riding a single speed, and I think that the 48x30 I'd get from big to big would suffice for anything I'm going to be doing. However I just rode the bike for a couple miles, and I believe the other two chainrings are bent into an oval shape, which isn't easy to tell when I've got it flipped over, but when riding I can really tell. So I have another question. How or where can I figure/find out what the bcd is for the middle/big chainring? Btw being that I'm having to replace the chainrings, I'd still like to know if I put a big one on the middle if there would be any issues. I'd like to be able to buy just 1 chainring and that would suffice.
