I recently bought my 1st road bike. Its a used 09' Fuji Newest 4.0 ( http://2009.fujibikes.com/Road/Sport/Newest40.aspx) with all stock components. I looking to upgrade my F/R brakes to Shimano 105s. My biggest question will these work with my stock parts. How difficult is this to do by myself? Can anyone point me in the right direction of links to good tutorials?
