Hi all, this one maybe better replied to from a framebuilder, and lord knows theres a few of them out there on this great list, I don't build frames or forks but happy to do anything else. I better get on with it before you all fall alseep, if my brain cells are in working order I thought there was a certain ratio between rider weight and frame weight?, looking forward to the postings on this......regards wayne davidson Invers NZ, still 20oC/68oF in my unheated bedroom.............
