Mountain biking can be an exhilarating sport that is challenging for you and your bike. As the only point where your bicycle comes in contact with the ground, your wheels are a crucial element in how well you perform on the trails. Selecting the right wheels for your bike is a matter of understanding your riding conditions and finding an appropriate mix of features and durability to meet your needs.
Size
One of the first factors to consider in choosing a mountain bike wheel is rim diameter. According to U.K. national cycling organization CTC, some mountain bikers may be inclined to buy large, 29-inch wheels because it is easier to roll over rocks, but this is not the best choice. Rims that are about 26 inches are better because the wheel will be stronger and give more clearance for the suspension.
Tire Width
Tire width can affect how much traction you get while riding. If your tires are too narrow, you may sink down into the trail or be more susceptible to flats. If your tires are too wide, you create an excess of rolling resistance against the ground, which can make pedaling uphill or through muddy conditions more difficult. The optimum width for a rear mountain bike tire is usually about 2 inches. The front tire can be slightly narrower, as it supports less of your riding weight.
Tread
Mountain bike tires come with a variety of treads, the pattern of which is largely irrelevant to how well it provides traction, according to Sheldon Brown. The height of the knobs is important and should be chosen based on your regular riding conditions. If you generally ride on a hard-packed trail, the height of the tread does not need to be much. If you are typically trekking through heavy mud, tall tread knobs are best to keep you moving forward.
Wheel Weight
The weight of your wheel plays less of a factor in mountain biking than it does on a road bike. However, one way that you can reduce the weight of your wheel and simultaneously improve it for mountain biking is to purchase a tire that uses Kevlar instead of nylon for the body. Kevlar not only is lighter, but it will also make your wheel more resistant to punctures and pinch flats when riding on rough terrain.
