Cross country:Mountain Bikes
A mountain bike is a bicycle specifically designed to withstand the toughness and roughness of a cross country ride. Compared to road bikes and BMX bikes, these mountain bikes usually have broader frames and tires to accommodate the rough road and terrain. These bikes usually have either front or rear suspension, depending on the preference of the rider. In some cases, both ends have suspensions. These are for the comfort of the rider while he is jostled as he traverses the rough road.
The broader and more knobby tires of the mountain bike are called knobbies because of the bumps and protrusions on them. These bumps or knobs are very efficient in “gripping” the rough terrain and maintaining their hold on the rough road. The smoother tires of road bikes cannot go up a rough road since these will just skid on it.
The different types of mountain bikes are usually categorized depending on their suspension. A full rigid mountain bike is one that has no suspension at all. Instead of the usual front suspension, it a fixed fork very similar to those of road bikes. A hard tail mountain bike is one that does have front suspension and does not have any rear ones. Some bikers prefer these kinds of set up since sometimes rear suspension can make the rider exert more effort because of the flex it gives.
A soft tail mountain bike is the kind with rear suspension but these are activated by the movement of the frame itself and not by the pivots. The rear suspension of these kinds of bikes is not as pronounced as those in the full suspension category. full suspension mountain bike has suspension in both ends, the front and the rear. This is a pretty comfortable bike to ride in rough road because the bike literally cushions you, at least most of the time.
The advantage of using a mountain bike is that you are physically fit and can go anytime to visit the great outdoors. It gives a great cardiovascular work out for the heart and burns a lot of calories also. One thing you must remember when you are out biking is to always wear a helmet. The helmet has saved lot s of lives already and it just might save your own. Helmets can withstand a pretty severe crash. Even if biking only in the streets near your home, always wear a helmet.
