Subject: [CR] Trek 620 with Tange fork

Hello All!

Spent this evening listening to the Mets get routed while taking apart my wife's 1984 Trek 620. Even though it misses the cutoff by one year, it is a steel lugged frame with traditional non indexed components and squeaks in as KOF.

The original specs from the vintage Trek website are at:


It has a Reynolds sticker on it saying it is made of "butted 531 frame tubes". The dropouts are Suntour and the fork is clearly marked on the steerer tube "Tange.3.J.R".

The headset is to me a curious affair. The specs call for a Stronglight B10 Black delrin headset. The threaded race and lower race seem to have metal cores embedded in plastic. It uses angular roller bearings in plastic races and the upper pressed race bearing surface is covered with a loose washer to provide a flat surface for the bearings. Is this just a cheaper version of the A9 headset?
