The Anatomy of Mountain Bike Wheels
Mountain biking is a popular sport that involves a specialized bicycle intended for the rough conditions that exist on off-road trails. This sport pits one cyclist against a field of other contenders all aiming to get through the course at the fastest possible speed. The terrain of an area has a major impact on the speed that these cyclists can travel at. The conditions can often be dangerous and hairy, therefore it is important to mountain bike riders to know that their mountain bike wheels are designed to handle the impacts and abuse that they are put through.
There are various categories of mountain biking, but all of these place the bike and rider in a similar situation, where it is the rider and their bike verses the natural terrain. The hardest part of competitive mountain biking is often the terrain. Mother Nature is very series opponent, but if you have the right bike and handle it properly Mother Nature can actually become your adversary rather than the competition.
Regardless of whether you intend to ride for competition or just for a way to pass some time, you will need to know that you have the proper equipment. Mountain biking is like any other sport or past-time in order to be proficient at it and stay safe you need to have the right equipment. In this case the proper equipment entails having a bike that is designed to provide you with the best possible ride while still holding up to the elements.
A mountain bike differs from a regular bike tin the way it is designed and constructed. These bikes incorporate features that are intended to handle the rough conditions that they will be used in. The elements of these bikes are all reinforced to provide durability and handle impact.
Most modern mountain bikes consist of front forks that provide dual suspension. These frames are mounted onto 26 to 29 inch wheels. These wheels and tires are wider and thicker than the tires and wheels on a standard road bike.
While mountain bike wheels are designed to be tougher and provide a better absorption to the shock of riding over rough terrain, they are still in many ways the same as wheels used on road bikes. Many of the features on a set of mountain bike wheels are the same as those on a road wheel.
A set of wheels is known as a Wheel set and are designed to fit into the frame and fork of mountain bikes via dropouts. The elements of a wheel for a bike are the same regardless of the type of bike. They all contain hubs, axles, bearings, spokes, and rims.
Mountain bike wheels contain what are known as clincher rims. These types of rims are used with clincher rims. This type of rim utilizes a wire or Kevlar fiber bead that interlocks with flanges in the rim. The tires contain a separate inner tube that is encased by the supports of the rim. This type of rim makes it possible to access the tube in the case of a leak and can allow the tube to be easily replaced or patched.
There are various types of mountain bike wheels the most popular is the 26 inch ISO 559 wheel. This wheel has a 559 mm diameter and an outside tire diameter of 26′. In many cases these tires may be tubeless, which allows the rider to run the bike with lower tire pressure, which permits better traction and shock absorption. Since they are tubeless they do not risk being punctured when they run with less pressure. Many riders will also use a sealing fluid that provides increased sealing capability and works well to avoid punctures from thorns or spikes.
Another type of mountain bike wheels is the 29 inch ISO 662. These wheels are 29 inches tall and use a clincher style wheel and are becoming increasingly more popular for cyclocross and cross country riding. These wheels which are also known as 29ers provide some benefits over other mountain bike wheels. These larger wheels handle rolling over obstacles such as branches and boulders, better than 26ers. They also handle soft materials such as sand better, and make a superior wheel for dessert conditions. These wheels are also ideal for taller riders.
There are also some disadvantages of 29ers; these include increased weight since they are larger. Weight is important in a mountain bike and therefore many of the components of a bike including the mountain bike wheels are constructed from a material that is light weight and durable. The increased size of the wheel means that it is more flexible which results in a weaker wheel. The other major problem is that many bikes are not designed to handle 29ers and must be customized to handle them.
