Early to mid 90’s but, I can do you a 16” GT Talera, needs a strip, clean, new gear inners and some wheels, will be a nice bike with a bit of attention.
I’ll swap out for a nicer saddle.
£25 plus post.
Got this, think it’s a 26.4, but could be 25.4, the middle digit isn’t very well stamped but is got a 2 and a .4 and a bit smaller than my 27.2 Seat-post. I don’t have any callipers sadly.
Here you go, SACHS Huret shifters, French brand.
Non indexed with smooth upshift and a non indexed but audible nice click down.
£10 posted. PM if you’d like them 😊
It might be we are both right, you are looking for an adapter that fits onto the treaded section with bolt holes for a regular bolt on six bolt disc.
This is one of the hubs with a cover for use without disc.
Maybe contact SRAM to see if they have any kicking about?
Let us know if you find...
