700c Road Wheels - Alloy Clincher

700c wheels are commonly used on road and hybrid bicycles, there are however significance differences in wheels which are designed for racing, touring and commuting / recreational use. Wheels designed for racing bikes are a combination or balance of aerodynamics, lightweight, stiffness, strength and hub and bearing quality. The wheels construction, rim material (aluminium or carbon-fibre), aerodynamics, lacing pattern, hub, bearing quality and type (sealed, looseball or ceramic) along with rider weight all need to be considered. Triathlon and Time-Trial wheels require performance factors such as aerodynamics, stiffness, hub and bearing rotational smoothness and lightweight. Triathlon wheels key focus is aerodynamics with many wheels with either aero rims or semi-disc rims and bladed aero spokes or full carbon disc for rear wheels. Full carbon-disc wheels offer a significant increase in aerodynamics and power transfer, however represent safety issues in crosswinds.
