Bike rims are the wheel of the bike without the tyres and tubes that connect on when it is ready to ride. A better thought is that the rim is the skeleton of the wheel, a strong stiff structure that holds the entire wheel in place. The rim is extremely important and needs to be carefully considered, especially if a person intends to buy a rim that does not already come with the bike. The best rims for road and track are made out of carbon and are extremely expensive. The best rims for other forms of bike riding such as mountain and BMX are made out of alloy or any other material that is both light in weight and strong in absorption.
