General Information

These shifters were very popular with racers who like the feel and that they slipped less than Campagnolo friction shifters of the same time period. Considered an excellent upgrade over all downtube friction shifters as well as modern counterparts by some. The open style lever was the later version of the Super LJ shifters.  Available banded and braze-on.  Also appeared in Spidel, Mavic, Gipiemme and Galli groups.  The steel clamp version would probably add 15-25g.

Braze on version carried model numbers: SLJ 5068 & SLJ 5059
