I understand it probably will end up being more expensive, but at the same time I really want to understand how every part of my bike works together and I felt like building it up from the frame would be a good way to learn. I'm also in the market for a new bike anyway, since I've been riding the same one going on 7 years now. My hope is that this bike will become my main bike for the next 7-10 years, so I'd like to do it right and make it something I really like.
