Thanks to Jon, Brian and Shane for input on this...  Jon had a stick tail database that although lost in a computer crash, still yielded some "guide post" dates.  This is an evolving process but this graphic represents the fundamentals of the early Quadangle Stick Tail era from 1982 to late 1985.

 

So the attached image is meant to be a "quick guide" for the early stick tail Quadangle era - from 1982 to LATE 1985.

One interesting thing about the stick tail era is a switch to a more standardized and detailed serial number format. This helps us see that frame changes did not end nor begin cleanly on Dec 31st and Jan 1st.  :lol:

 

I'm going to share some serial information provided by Jon, but we should bear in mind that this is based on serials collected and there may well be other examples that would push these dates around a bit.

 

That said, the first iteration of the 4130 Chromoly stick tail was short lived and they went to Reynolds quickly. Jon Hoffman had a stick tail database that was lost in a computer melt down, but stand out details include that the earliest 4130 stick tail Jon had logged was serialed with a Sept 82 date. Conversely the earliest Reynolds that Jon was able to log was March, 1983. So with current evidence we can see that the earliest stick tails were 4130 and went from at least 9/82 to around March of 1983. Then they went to Reynolds and that went until the return to 4130 and a design change in late 1985.

I have one of the blueprints (a copy) of the Stick drawn over the looptail that I got from Scot... can't remember the dates though.

I have a 4130 stick tail but it’s been in a box. I’ll try to pull it down to give you the serial number

January 1983 BMXA had a test on it. While it talks all about the use of 531 Reynolds, the bike in the pics is clearly a 4130 Chromo Quad with its tiny seat/chain stays.

* my pics are coming out sideHays * 🤣🍻🤣

Hold tight!
