How Important Are Mountain Bike Frames? Mountain bike frames are the basis for the bicycle’s sturdiness, weight and general appearance. This is why when purchasing new mountain bikes, most cycling professionals and enthusiasts give the frames a thorough check instead of just giving it a casual or cursory look. Though it may appear similar to a casual observer, each frame has different sizes, symmetry and materials used which is tailored for a particular body structure of the cyclist who will be riding it. Most of the mountain bike frames available in the market today is usually made up of aluminum steel. This makes for a sturdy, yet very light structure, making it easy for the cycling enthusiast to maneuver. Although there are still frames that are made up of galvanized iron or steel, these are rapidly fading fast into oblivion and is being replaced by aluminum and some other lighter materials like titanium. Naturally, if you are a cyclist, you always undoubtedly would prefer the lightest material to make up your frame. This is where the ultra lightweight metal call titanium comes in. Bike frames that are made of titanium are almost weightless, yet are sturdy enough to withstand the rigors of cross country cycling. The only problem with titanium as of the moment is the exceedingly high cost which only a few cycling enthusiasts can afford. This is why most cycling enthusiasts still prefer their bikes to have aluminum frames because they are very affordable. Though they may not be as light as those frames which are made from titanium, aluminum frames do exceedingly well in various types of tracks. Another area of consideration which you must carefully check out is the size of the frame. Bear in mind that mountain bike frames have different sizes which correspond to the height and body physique of the cyclist who would be riding it. The size of the mountain bike frame is usually determined by measuring the expanse of the frame from the center of the base bracket to the uppermost portion of its top tube. Getting the right bike frame is very important since it can affect the way you maneuver your bicycle. Remember that all frame sizes are influenced by the unique body structure of the cyclist who will be riding it which is why you have to carefully select the mountain bike frame with a size that closely matches your own body physique. Once you have correctly determined the weight and the size of the mountain bike frame that you consider perfect for your body structure, you can now begin that exciting cross country journey that you have been longing to indulge into.
