Road Bike Wheels
Although modern wheels are getting more and more hybrid, and generally better at performing multiple functions, there are still specialty wheels that work better at one job than others. If you're a hill climber, then you'll want nothing more but to shed as much excess weight as possible, so therefore a light wheel is the best you can buy. However, if it's wind resistance that you want, to keep to a minimum then you'll need aerodynamics over light weight. Aerodynamics are important for speeding through the flats and straight, rolling terrains.
Here at ProBikeKit Canada you'll find all types of road bike wheels, including lightweight and aerodynamic variants, and you can check the weight on the product pages.
