Tires and Rims

Tires and their rims need to be aerodynamic, durable and lightweight and this all affects the bike's climbing, acceleration and handling. Box-section rims are lightweight, accelerate quickly, and provide the most comfort whereas aero-shaped rims are stronger, have less wind drag, and are stiffer which means less comfort. The choice of rim will come down to personal preference. So if you are reasonably light and love riding at a leisurely pace on rough pavement then the box -section will be the best choice however if you are heavy set, competitive and ride on smoother pavement then the stiffness of the aero-shaped rims will suit you better.

With tires, essentially the thicker they are the longer they will last, the more they absorb road shock but they will have more friction as there is more tire on the road, so racing styles will always be thinner. So if you are looking at all of the road bikes for sale, then keep all of these variations in mind and decide on what specific features are important to you.
