I am the original owner of a Miyata 210 that has between 25K and 30K miles on it. On a recent ride, the bottom of one of the two front forks broke off where the front wheel attaches. I have the piece, about the size of a quarter with the slots for the hub. I'm assuming that a weld would never hold. Any idea where I could get a replacement front fork? The bike has a 27" frame - extra tall.
