I love my bikes. I replace parts as needed. Some of my bikes are like the old axe that's had the handle replaced 3 times and the head replaced 5 times, but its still the same old axe. If your bike is run over by a bus and every single component is destroyed you simply replace every component, it may look like a new bike but its not, its the same old bike.
