I don't know how many people here have used pcpartpicker.com before, but is there a site like this for bikes? Best parts of that site for me are:
- part compatibility: if i pick a certain motherboard, only ram that is compatible is listed
- graph of price over time: for each component i get to see how various online retailers change the price of it over time. that way i know to hold off till black friday to get certain parts
- list of basically every part: if i wanted a hard drive in my comp, i get a list of just about every manufacturer
I'm not too savvy on bike building sites, but I'm sure there's a slick one out there. Any suggestions?
