General Information
This lug type was used on Trek models 660, 520, 420, and 400. seatpost clamp is integrated into lug. Fancy carving and etched Trek logo on both sides. Both inner connection points for the seat stays are marked. The right (drive side) seat stay is marked "73.0", perhaps referring to the seat tube angle requirements for this lug. The left (non drive side) stay is marked "TSI 51.1 6.7".
