This is something interesting about Trek- if you noticed the description of 531CS specifies a CrMo butted steerer- but a lot of the 600 series Treks I've seen have Tange steerers... As you might be aware, Trek played fast and loose with the "made in the USA" statement- as the fork and rear triangle were brazed in Japan (I've read by Tange)- I wonder if that has something to do with why there's (often) a Tange steerer on these bikes.
As a total aside- if you'll notice there's no 600 series bikes in the 1986 catalog- but the 400 series bikes have 531 main frames but Tange stays and fork... just interesting to me.
