My old bicycle

[DazzaTD5]

Decided to strip down and refurb my mid 80's push bike.
Although the cost of the dutch made leather hide seat and grips, Continental tyres and tubes were worth more than the old pushy itself, the end result I was pretty happy.

That is an interesting old bike. What is the maker? What is its provenance and history? Looks American to me.

Yes great pick there, how did you pick it as american?

Its a Diamonback, 1989 on the frame from memory, no history I purchased it off another casual bike rider such as myself, was painted in a horrible bright green.
The wheel guards are vintage Schwinn which I scored from a mate of mine.

The frame and handlebars style is what Americans called a Roadster. Does it use British Standard Cycle threads (BSC or CEI) or American threads?

Ahh good info.
Well as for the thread, I dunno... the rear hub I found nuts in my workshop to fit. The front was the odd ball that for the life of me I couldn't find new nuts to replace and had to be content with using the original. So I'm guessing the front is BSC which means its likely to have been replaced at some point

if that makes sense

I asked because I did not know if USA bicycle manufacturers used US threads (NC,NF, NEF, NP etc) or if they used the bicycle industry standard of BSC/CEI. Even Asian makers used BSC at least until fairly recently. BSC nuts and bolts are hard to find but are stocked by Bruce Gardner B.S.F. Bolts Melbourne and Classic Fasteners Adelaide. They are always either 26tpi or 20 tpi in larger sizes. 3/16" is 32tpi. I sold lots of BSC taps and dies to restorers of British motor cycles. I can only recall one sale to a bicycle restorer. A chap from Port Hedland who had found a Bates Cantiflex put out on the street for a council clean up. Looked like a wrecked old grid but its unusual design prompted him to take it home. Reading the internet convinced him it was a very worthwhile project. For thirty years Bates Cantiflex was the choice of the top level of professional racers.151601151602
