hello, i remember this frame set from back in the 70s...interesting that part of your sales info mentioned that there were NO CRACKS....as i recall there was a real issue of this failure especially among those who bought and raced this frame set...i think part of the allure was obviously a saving of weight...its imperviousness to the elements, lively feel w/ rigidity...all those good things one needed to say as sales points....i suppose the thinking was too conventional back then to just go for a gound up redesign, retooling for that material...a larger diameter tube may have solved some of those stress issues...i was also edified through the conversations of the day that the only way to really state, no cracks, was to magnaflux the frame...just curious how you arrived at that point where you could say, no cracks...i mention this as a point of interest and possible discussion w/ all of you out there who know the skinny on this frame, especially w/ all the interveneing years since its arrival for the pros and cons to be more a point of history than speculation...it's interesting also to see that it valued at approximately the same price that it sold for new, or a little less. happy thanksgiving to everyone. charles flaherty baltimore maryland usa
