What is the earliest occurrence of the wishbone seatstay?

[classen]

I see the wishbone rear seatstay showing up on a lot of bikes in the late 80s , but I'd like to know where this trend started. Is there a particular frame builder that this can be attributed to?

dunno
was it a roadie thing?
more likley to be for a material other than steel (tho used on steel frames )
maybe early carbon frames ,just thinking it may use another materials
properties better
my nishiki cascade has a wisbone rear but i think thats a 92

I had a steel mongoose from around 86/7 with a wishbone rear

Ok I was digging through the MOMBAT site and found several references from 1988/1989 that indicate that Mountain Goat's Jeff Lindsay designed the uni-stay in collaboration with Tange. Another article from Bicycle Guide magazine (not sure of exact date, but it's entered under 1989 on MOMBAT) claims that Mountain Goat had exclusive use of this custom tubing from Tange for 6 months.

The uni-stay (aka wishbone) also appears in several 1990 Rocky Mountain models (when Chris Dekerf was welding there).

There is also a mentioned on MOMBAT under the 1988 section of Raleigh:

All Technium mountain bikes use a Monostay Wishbone on the rear and chain stay mounted brakes.

So maybe Mountain Goat only had the exclusive 6 month licesne for the Tange produced uni-stay? and Raleigh used their own design?

I'll continue to dig into this. Maybe the design was first seen in road bikes?... an area of which I don't have too much knowledge

There will be more roadbikes with a monostay and that pre date all above mentioned MTB's.
