To add to this, smaller size high end frames may well be built using lighter gauge tubes or in the case of carbon frames using less material. Small frames are designed for smaller, lighter riders and may not be up to the demands put on them from taller, heavier riders. As well, longer seatposts, stems and wider handlebars increase the stress that bigger riders put on their bikes. Professional riders often ride frames that are much too small for them, a good example of this was Ryder Hesjedal who rode a bike a couple of sizes too small for him in order to achieve a better aerodynamic position because of his height. However, as a pro he never had to buy a new bike because it broke during a ride and he had multiple bikes each year at his disposal. Every year, he would have been given new bikes from the current model year so he never was riding a bike more than 1 year old
