Hi

I am trying to find out the value of an old road bike I have. The bicycle actually belonged to my Grandfather who was an amateur champion cyclist in his day. I dont believe that this bike was used in any of his races. It has been sitting in his shed for the past 30 years or so I think.

The brand says Alps Industrial Ltd on the handlebars. It has very cool patterns on the corners of the frame.. The tyres look like they are the original tyres. I cant seem to find any other markers to determine type of brakes, etc but really don't know where to look, and what to look for.

Can anyone help?

That's very nice lugwork. This bicycle is a lot older than 30 years. Based on the rust, it looks like all of the components are steel. Correct? If you're not sure, check using a magnet.

Do you a caliper to measure the diameter of the seat post? If not take a thin strip of paper and wrap it tightly around a cleaned area of the post and mark where it overlaps. Remove the paper, and measure from the end to the mark, to the nearest 0.5 mm. Divide this result by 3.14 to determine the diameter of the seat post itself and post the result. This will give us a good idea of the level of tubing inthe frame.

I'm sure someone will want a good drive side photo of the crankset and rear hub.

Hi
If my calculations are correct, the diameter of the seat post is 27.07
Yes, you were right in that the frame is steel.
I've attached some more photos, particularly of the drive side.
Thank you for your help.

That seat post measurement indicates a high grade frame material. Given the apparent era, it's most likely Reynolds 531. Offhand, I don't recognize the chainring pattern. Hopefully, another member will.
