BSA track cycle racing

[Roby]

Goodmorning everyone, I have got a BSA track cycle racing. Serial number 3521, I have just bought it. I'll like know how old is it. And what a Kind of wheels I must put in. I live in Italy and the bike was sold here. Italian people told me to find hubs SIAMT on the flange side and wooden wheels. Lightweight BSA Rat-trap pedals. Is it right?
Thank's a lot everybody will Help me.

No idea on age but it's certainly a very nice bike. Quite rare as well I would assume?

now that is nice @Roby

an oily rag resto job on that please do not loose that patina

The teeth are a bit gappy on that chain ring? A nice bike.

That chainwheel is 1" pitch - can chains still be obtained?
I'd love that bike - my dad was a tracky and rode one similar with 1" pitch chain. Lucky bloke picking that up!

One of the photographs shows a chain looped through the rear triangle - I guess this is the correct one inch pitch; if so, treasure it, because another would be difficult to find in good condition. I don't know how old the frame is, but the veteran cycle club may be able to help. They have online copies of many BSA catalogues dating back to 1900.
You could also contact them with a query: cyclehistory@gmail.com Please keep us informed if they tell you details of your frame.

NB to other CC members - please remember that Roby has (very good!) English as a second language, and avoid slang/abbreviations which may be difficult to translate.
Yes, I'm looking at you, @biggs682 with your "resto job"! Roby, he means "restoration", just in case you're struggling - if not, please forgive me, both of you!

After the late 1920's. Chrome plate was invented in 1924 and the big cycle manufacturers started using it in 1927. The geometry and certain details (headset) suggest late 1930s.
And now for some wild guesswork. In your wooden wheel thread the hub has been cut out. In 1936 and only for a couple more years, Constrictor sold some hubs (made by BSA) called circumferential, the spoke came from the rim, wrapped round a post on the hub flange, and went back to the rim so had a nipple on each end and no bent head to break. These hubs were wildly popular but as I said only made for a short time. My guess is someone has taken the hub out of your wheel to put in a better (post war alloy?) rim. So that wild conjecture supports a late '30s date

I would tend to agree with most of "Hover Fly" description. I think chroming became vogue in 1929/30. Inch-pitch chain drive was popular on racing bikes between 1900 & late 1940s. The bars appear to be South of France type.

After re-examining your images, I'm fairly sure this is a Pre-WW2 frame. From research I've done in the past (my own BSA's), they stopped using the water slide oval transfer in 1936. It was replaced with a alloy oval badge.

I have seen some BSA catalogues , https://oldbike.wordpress.com/1936-bsa-catalogue/ they are well done but there aren't track cycle there. The chain is the correct one, I'll write to cyclehistory@gmail.com. Thank's

What is written on the sides of the crank arms, near the spindle? I see writing in one of the photos, but can't make it out. If it happens to say "WILLIAMS" then you should find a date stamped on the other side. The date is a code involving a couple letters next to a dagger-like mark. If you have that, google "Williams Date Codes" and you should find it right away.

I'm guessing 1935 -1939 or so, but that's really a guess. What do I know.

 

[Roby]

Thank you very much. In the the crank arm You can see a " F" and " PATENT 13695/..." . " 22" is the theet's numbers, but what "F" means ?
