    Caution;  Merge;  Workers Ahead! 1991 Trek 970 Shimano Deore LX SLR Plus right/rear 7-spd Shifter/Brake Lever)

    This is my dilemma:

    My 1991 Trek 970's Shimano right/rear 7-speed shifter failed (shifter is integrated with brake lever). This purely thumb-operated shifter is no longer available (per local Trek dealers and Trek itself) and I have searched online stores, auctions and parts suppliers (including LooseScrews.com) without success.

    I am willing to change to a compatible component (7-speed thumb-operated shifter) but I lack the technical expertise to precisely describe what need. Furthermore, I do not have the specific Shimano part number to use as a reference (I have learned the hard way that Deore LX is much too broad). The only markings I can find is SLR Plus.

    I'm stuck and Trek won't help (ask me for copies of emails if you are interested).

    Any suggestions on how I might find this component?

    Does anyone know how I might determine the specific Shimano part number for the original component marked "SLR Plus" (for a Deore LX 7 speed rear derailleur)? My hope is that having the specific part number will allow me to narrow my search for it on the Internet.

    Since this shifter/brake lever is no longer produced by Shimano, I expect that it is in short supply. As such, having a back-up option of using a compatible unit should help expand my choices. Do compatible units exist?

    Thanks in advance!

    You can scour ebay for a replacement set or just a right side shift/brake lever. The push-push rapid fire shifters were only offered from 1990-1992, so there weren't that many made to begin with. I don't have a part number for you.

    Another option would be to replace both units by finding a set of center pull cantilever brake levers along with any set of shimano compatable seven or eight speed MTB shifters.

    I wouldn't be too hard on Trek. The bicycle industry reinvents itself every four years or so. Parts that are over that age are usually considerd hopelessly obsolete.

    Thx for the tips.

    After an extensive search
    (I spent more hours over more days than I would want to admit), I found the specific part number(s) from a German site, no less.
