Shimano ST-A050 — what is that?

Cuervo Blanco · Aug 26, 2018

Recently I got such a shifter with the marking ST-A050. It looks cool and works fine. Nowhere can I find information about this model. What group Shimano, what year of release - Google can not find anything. I write here in the hope that someone has information about this model.
P.S. And forgive me for my awful english.

Re:

I think you'll find it's a flat-bar road lever/shifter combo. It may say the bar clamp size on it?
Should be 3x7 speed shifting, so more for touring/trekking/hybrid use I guess.
I'm not sure what level it is, but probably lower end of the Shimano groupset range, think of Claris sort of level.

If you search Google there's a few hits for ones for sale/sold on ebay.

This shifter looks like Deore DX, and works no worse.
⌀ 22.2mm

The shifter is the same as used for the 100GS through to the deore LX for the 1992 model year.

100GS is the same as Tourney. I don`t understand. You want to say that the shifter from 100GS was screwed to the body from Deore LX?

Re:

Essentially the same shifter unit was used, yes, the differences were in the materials used for the brake levers, as the shifter unit just bolts onto the lever assembly.
