So I bought an old Bianchi Tangent a few years ago and I am now becoming more of a biker. This bike is a hybrid and I use it mostly for road biking. I was wondering if it would be better for me to modernize this bike with new handlebars, new gears, and everything new required to add those parts or to just buy a new road bike? The guy at the bike shop said that it would cost about $500 to get all of these changes done.
