A Trek Tx770 with all original parts or a Trek tx770 with 9 speed Ultegra? I would think that the modern 9-speed Ultegra parts would outweigh the value of vintage cyclone parts, but I also know that things like powdercoating a frame can lower the value, even though it would be a stronger finish.
I'm half way through a conversion now. I'm just waiting on a smaller FD clamp. It's full Ultegra except for the Easton EA50's and I was just curious how it will affect the value.
