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!
