 Wheels, wheels everywhere, but which one is the right one for you? We're here to break it down and make life a little easier today on Purefix TV. If you're looking to upgrade your wheel set, you have a lot of choices. Most single speed fixed gear bikes uses a 700C sized wheel. So now you know you're rolling on 700s, it's time to choose the rim. This is where you can get creative because rims come in all different sizes and colors. Rims are measured in millimeters based on the depth of the rim. This is a 60 millimeter rim, also called a deep dish. Other deep dish sizes are 50 millimeters and a 40 millimeter. The deeper the dish, the heavier the wheel will be, but it also makes the wheel more durable, stiff and aerodynamic. This is good for track racing, but you know, if you're trying to shape some weight off your bike, you might want to go with a smaller size rim. If you're running brakes, you might want to use a wheel with machine breaking surface. This is an unpainted strip that allows your brakes direct contact with the metal so that you can stop on a dime. Machine Pro wheels are light with a 30 millimeter rim, and they come with sealed bearings so they don't need much maintenance and provide a smoother ride. Your brakes will still work on painted rims, but you might scratch up your paint job. Check out our blog post for more info, and if you have any questions, drop a comment below.
