Hi there, I’m new to the forum and fairly new to cycling. I’m opening a machine shop at the end of the year and need to find some products to make at night ”lights out” to make the most of the expensive machines I’m investing in. I had thought titanium screw kits would be a good start so was looking to find out what would be common bikes to cater for? I also thought about SPD cleats made from titanium? Any suggestions of components that I could make and sell in large quantities and where to market them would be much appreciate. Thanks for your time.
