My new SG A-53T chainring didn't come "ramped and pinned". I think this means the teeth aren't cut and beveled and there aren't any pins to aid in shifting. It's a beautiful chainring with a much nicer finish than the stock one it replaced. I bought it from my local and knowledgeable LBS to work on a full ultegra 53/39 double setup. Will I be giving up better shifting for better appearance? What are the differences in the various versions? No, it's not Biopace.
