Zeus Pista Chainset

[dttlincs]

I got this Zeus chainset and bottom bracket today.
Could anyone help with age of it? It is 50t with threads for dust caps.
Could bottom bracket be titanium?
I bought it without knowing tread type on BB but it is english which is great as it fits the bike i wanted it for. Thanks

I would say mid to late 70’s

Does a magnet stick to the axle?

Re:

OK. Will do. Thanks

Re:

It is magnetic so not the titanium one.

Re:

Looks like bb is likely a Zeus Criterium Track from what I can see on Velobase.

Lurking somewhere, I think I have the matching Zeus BB pin spanner for the adjustable cup. I vaguely remember it as identical to the Campagnolo equivalent but without the anti-tarnish finish.

Re:

Don't Zeus chainsets have a different BCD to most other sets? I remember that the 'small' 5-pin cranks wouldn't fit TA etc. rings so were the 'large' 5-pin the same? The one here looks smaller and my 1984 RonKit catalogue states that chainwheels range from 36t upwards.
