Hi guys, I'm a studying mechanical engineer from Adelaide Australia. I'm looking at making my first aluminium bike frame and have a heap of questions. To start with can I just use off the shelf aluminium from a supplier? And what's the best way to make chain stays as they are probably the most complex part. I'm designing the bike on CAD first and starting with single speed for my first one to see how I go and I'll move on from there. Any other advice?
