I have been looking at a new bike, and have decided on a Canondale Rize 4 (alum frame, fox fork, fox shock, hydro brakes) and now have to make a harder decision..... I have the chance to buy a Rize 1 (carbon frame, carbon lefty fork, etc), weight is 22 lbs !!!! I can buy the carbon bike for the exact price of the Rize 4 model. Its a new bike, it just has been parking lot tested at the LBS. I will never race, and I tip the scales at 200lbs. Do I need a carbon bike, or should I stick with the stronger Rize 4? I only ride our local trails.... maybe twice a week if im lucky. I need to decide in the next few days or let my buddy take it.
