TK (framesets)

1979

Overview

This frame design was also used for the works Pro-Star, though the later was advertised as a full Chromoly set (which is not the case). Only logical info as to what the TK refers to is 'Trimoly Kit'.

Available as either a 'Centurion' (A-Gussett) or 'Diamond' gussettHere you can see the two types of gussett available for the TK, these being the Diamond or Centurion, (both framesets were identical apart from this). Note the transparent 'background' decal for the seatpost tube and the Tange forks.
