Hi. I don't have an 18" Aurora Avalanche frame (well actually I do, but I am not selling) but I have everything (!) else to build a 91 to original spec, incl. fork, stem, tires, grips, BB, HS ... In case you are not looking to go original, I also have some very rare bits that may be of interest (Scott SE U-brake and matching front!). Let me know if you need anything. BR Pete
