I have a bicycle frame that's really heavy. It's a mountain bike frame with shocks, so I decided to replace the entire frame with a city bike aluminum frame(I only use the bike if I have to pick up/buy some stuff near home). How do I know if the frame that I replaced is a titanium/steel?
I got the bike as a present from my uncle almost 6 years back, I don't have an idea about the brand, it's just the entire frame is not your average frame, it's somewhat heavier than other bikes( I compared it with the aluminum frame I bought/ plus a couple of my friends bike)
What methods/techniques should I use to know what type of frame do I have?
