New road bike wheels can make a huge difference to the performance of your bike, having an impact on the bike’s ability to accelerate and handle as well as hold speed. Investing in a quality set of road bike wheels can be the single most significant upgrade you can make. Climbers will want the lightest wheels possible, while aerodynamic rim profiles add weight but improve straight-line speed for racing and time trialling. A growing trend for wider rims allows wheels to be run with higher-volume tyres for additional comfort. Ensure your chosen wheel matches your braking system.
