I'm very new to this I bought a new fixie its a Vilano with stock everything, I want to spend all of the money on everything else except the frame itself. I just don't know what is quality and what is bs. I know that I definitely need new pedals, a saddle, wheels, and tires. The rest I can live with for now. What is a good way to learn about the different brands and mfgs without actually purchasing them?
