Vintage Triumph help with serial number
 

Hi All,
I have an old Triumph cycle with a serial number of ND5259050. Im trying to find out its age and model. Could any body point me in the right direction or offer help please?

Hi and welcome to the Bike Forums.

Appraising a bicycle is difficult when information is sparse. To best help, we need at least three things - where you live (market strength varies from city to city a lot), condition of the bicycle and pictures.

You will have to post a minimum of 10 times, spread over at least two days (this is to prevent spamming). Show the drive side of the bicycle and any special identifying features, such as drop outs (where the wheel axles fit into), head tube lug work, seat tube lug work, and anything else that might seem to be useful, such as a serial number.

Armed with that, thought there are no promises, you might be amazed at how quickly accurate information comes back.

Again, welcome and tell us a bit about the bike. Size, condition, were you live, how you got the bike, each in a separate post - that would be four post right there.

Randy’s autoresponse not withstanding, the serial # scheme on that bike won’t give you much. If it’s a Sturmey Archer 3-speed and the rear wheel is original, the date on the hub is the best way to tell (a system that has month and year of manufacturing: 68 2 = Feb 1968). Otherwise, sharing pics is the best way for some one to figure out the model, but the forum won’t let you do that until you’ve made at least 10 posts.

Thanks - That worked!
 

Thanks for taking the time to answer my question. Its turned out its a Feb 1975 hub, so I am presuming the bike is a similar age.
I found it going with a load of scrap bikes on Facebook. Its in good condition for its age but some of the chrome needs a little TLC.
I was thinking this would make a nice little project to do up. Would you advise getting it re-chromed?

Thanks for the advice I will try and produce some posts on the subject.

You'd be surprised at how well chrome may clean up.
Re chroming is usually not cost effective when used parts in better condition are available, unless it's something highly collectible or rare. .

The frame was manufactured by Raleigh in their Nottingham factory during March 1975.

No, I don't think it would be a good idea at all.
