Currently, I have a cheap, stock 2200/Sora equipped bike with a Shimano 105 hub/Mavic Open Sport wheelset. I bought the bike sans the wheelset and bought the wheelset knowing I would be upgrading frames and other components in the future. I am looking to build a Soma Smoothie with the end goal of having a very solid, comfortable road bike that doesn't break the bank. I will be using this for recreational riding only.
In starting to compile the pieces, I am finding quite a bit of older NOS Shimano 105 9 speed parts available.
My questions are:
Would it be crazy to build up a bike using these older, but never used, components to complete the build?
Is the older Shimano 5500 series 105 stuff worth buying and using?
