Just picked up a 1977 Trek TX900 on ebay.Full nuovo record,columbus sl,drilled lugs.Seems to be sort of a rare bird.Does anybody know how many of these were produced back in the day,and perhaps who would have had a hand in brazing these early machines.Can't wait to get this thing on the road......... Cheers, Todd Kielman Chicago Again violating the "one in,one out" rule.
