I stood up and broke the chain on my old mtn bike and it took out the front deraileur and front chainrings. I had another ride planned for the next day and didn't want to jump into buying a bike right away, but fixing a nearly 20 year old bike seemed silly.
The purple Stumpjumper was a demo bike and they let me use it for the rest of the week. (probably helped that he remembered me buying the Bianchi Giro there a couple years before) I got spoiled pretty quickly going form the old no suspension bike, to a full suspension. (hydraulic discs are nice too) With the bike absorbing all the hits, I can pump the tires hard and ride in comfort and low resistance.
