The Beauty Of Mountain Bike 2016 Edition, A mountain bike or mountain bicycle (abbreviated MTB; or ATB, for all-terrain bicycle) is a bicycle designed for off-road cycling. Mountain bikes share similarities with other bikes, but incorporate features designed to enhance durability and performance in rough terrain. These typically include suspension on the frame and fork, large knobby tires, more durable heavy duty wheels, more powerful brakes, and lower gear ratios needed for steep grades with poor traction. Since the development of the sport in the 1970s many new subtypes of mountain biking have developed, such as cross-country (XC) biking, all-day endurance biking, Freeride-biking, downhill mountain biking, and a variety of track and slalom competitions. Each of these place different demands on the bike requiring different designs for optimal performance. MTB development has included an increase in suspension, typically up to 8″ or 203mm, and gearing, up to 30 speeds, to facilitate both climbing and rapid descents. However, advancements in sprocket design has recently led to the „1x (pronounced one by)” trend, simplifying the gearing to one Chainring/Sprocket in the front and multiple sprockets on the rear of the drive train, more commonly, 9, 10 or 11 speed.

Cross country (XC) mountain bikes are designed primarily around the discipline of cross country racing. Cross country racing with its emphasis on climbing as well as speed and endurance demands bikes that are both lightweight and efficient. In the 1980s and early 1990s XC mountain bikes typically consisted of a lightweight steel hardtail frame with rigid forks. Throughout the 1990s XC bikes evolved to incorporate lightweight aluminium frames and short travel (65 to 110 mm) front suspension forks.

Trail” Bikes are a development of XC bikes that are generally used by recreational mountain bikers either at purpose built „Trail centers” or on natural off-road trails.

Enduro/all-mountain (AM) bikes bridge the gap between cross-country and freeride bikes, such as the Trek Remedy series, Specialized Enduro, typically weighing between 13 to 16 kilograms (29 to 35 lb). These bikes tend to feature greater suspension travel, frequently as much as 6 inches (150 mm) or 7″ of front and rear travel, often adjustable on newer mid- and high-end bikes. They are designed to be able to climb and descend well, these bikes are intended to be ridden on all-day rides involving steep climbs and steep descents, hence the term 'all-mountain’.

Downhill (DH) bikes typically have eight or more inches (200 mm) of suspension travel. They are built with frames that are strong, yet light, which often requires the use of more expensive alloys and very recently, carbon fiber. In the past few years, lighter downhill bikes have been getting below the 40 lbs mark (18 kg). Due to their typically large or high gears, long, plush travel and slack geometry angles, Downhill bikes are ideal only for riding down dedicated downhill trails and race courses. Downhill bikes have the most sag of Mountain Bikes to get ample traction to go fast over bumpy trails. Head Angles are often as slack as 62 degrees. Several types of bicycle speed records have been registered downhill.

Freeride (FR) mountain bikes are similar to downhill bikes, but with less emphasis on weight and more on strength. Freeride bikes tend to have ample suspension and typically have at least 7 inches (180 mm) of travel. The components are built from stronger, consequently heavier, materials. They can be ridden uphill, but are inefficient and their moderately slack head tube angles make them difficult to maneuver while angled up a hill or traveling at a low speed. They are effective on technical downhill trails.

Slopestyle (SS) combination of Dirt and Freeride

Trials bikes are set up very specifically for the purpose of bicycle trials. Two varieties of trials bike exist, those with 26″ wheels (referred to as 'stock’) and those with 20″ wheels (referred to as 'mod’ – because historically they were modified BMX bikes).

Dirt jumping, urban and street mountain bikes lie somewhere in between a BMX bike and a freeride bike. They are typically very strong bikes, with 4 to 6 inches (100 to 150 mm) of front suspension, and rarely any rear suspension………
