I recently bought a 1997 GF Big Sur, and the suspension fork is all but toast. I want to replace it with a rigid fork. It takes a 1 1/8 inch Threadless, which I have found on-line, but they are double the price of the threaded. Just curious why they are so expensive. Is this a particularly coveted item? Anyone have any suggestions on where I can find one in the $30-$40 range? Anyone have one that are willing to part with for a reasonable price? $70+ seems a bit over the top for a fork to put on a 20 year old bike. Any insight would be greatly appreciated. Thanks!
