Frame Material??
 

Hello,

I have a road bike frame made by PACONI in Melbourne Australia. The frame has lugs and weighs 2.2 KG. The problem I have is that I do not know if it is an Aluminium Frame (screwed/glued lugs) or a Cro-mo frame.

Is there any way to tell? Or should the low weight be a good indicator of material used?

Thanks.

magnet will tell if it's ferrous or not.

Thanks jhota, a great idea.

Without knowing the exact Alu or Cro-Mo it's going to be impossible to tell by weight alone. Lugs and age are usually an indicator that it's steel, and often Aluminum will sound different when you tap it but niether are very definitive.

Give us a picture, serial number, age, more details...found a business listing for Paconi Racing Frames, maybe give them a call and ask.

Is the weight with or without a fork?

Thanks for the info. I was going to call the bike company a while ago but there are no serial nos or model names on this bike - just the brand and the maker's name.

I tried the magnet method as suggested in a previous quote and I suspect that the frame is steel (cromo) as the magnet stuck to it. I also tapped the frame, and it did sound a bit like aluminium (a sort of flat sound, whereas steel makes a higher tone when tapped)

It is the weight fully stripped without forks.

If I find that it is aluminium I will sell it, as I only ride steel..

If a magnet sticks to it as you say, it's not aluminum. And at a frame weight of 2.2 kg (4.8 lbs), it sounds like a chromoly frame of one sort or another, high-ten steel would be heavier-
