Mountain-bike
A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which makes them heavier, more complex and less efficient on smooth surfaces. These typically include a suspension fork, large knobby tires, more durable wheels, more powerful brakes, straight, extra wide handlebars to improve balance and comfort over rough terrain, and wide-ratio gearing optimised for topography and application (e.g., steep climbing or fast descending). Rear suspension is ubiquitous in heavier-duty bikes and now common even in lighter bikes. Dropper posts can be installed to allow the rider to quickly adjust the seat height (an elevated seat position is more effective for pedaling, but poses a hazard in aggressive maneuvers). Mountain bikes are generally specialized for use on mountain trails, single track, fire roads, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UCI Mountain Bike & Trials World Championships
The UCI Mountain Bike World Championships are the world championship events for mountain bike racing in the disciplines of cross country, downhill, and four-cross. They are organized by the Union Cycliste Internationale (UCI), the governing body of world cycling. The first three finishers in each discipline at the World Championships are awarded gold, silver, and bronze medals. The winner of each discipline is also entitled to wear the rainbow jersey in events of the same discipline until the following year's World Championships. Unlike other UCI-sanctioned mountain-bike races, the competitors in the World Championships represent national rather than commercial teams. The World Championships are usually held towards the end of the season. History The first UCI Mountain Bike World Championships took place in Durango, Colorado, USA in 1990 and featured only cross-country and downhill events. A separate UCI Trials World Championships had been held since 1986. From 2000 to 2016, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joe Breeze
Joe Breeze (born 1953) is an American bicycle framebuilder, designer and advocate from Marin County, California. An early participant in the sport of mountain biking, Breeze, along with other pioneers including Gary Fisher, Charlie Kelly, and Tom Ritchey, is known for his central role in developing the mountain bike. Breeze is credited with designing and building the first all-new mountain bikes, which riders colloquially called Breezers. He built the prototype, known as Breezer #1, in 1977 and completed nine more Series I Breezers by early 1978. Breezer #1 is now in the collection of the Smithsonian Institution’s National Museum of American History. Breeze, a road bike racer through the 1970s, was among the fastest downhill racers at Repack, mountain biking's seminal race held west of Fairfax, California. He won 10 of the 24 Repack races, which took place between 1976 and 1984. Breeze is a charter member of the Mountain Bike Hall of Fame; he was inducted in 1988.

Bicycle Wheel
A bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called a wheelset, especially in the context of ready built "off the shelf" performance-oriented wheels. Bicycle wheels are typically designed to fit into the bicycle frame, frame and bicycle fork, fork via Dropout (bicycle part), dropouts, and hold bicycle tires. Invention The first wheel to use the tension in wire wheel, metal spokes was invented by George Cayley, Sir George Cayley to achieve lightness in his 1853 glider. Construction The first bicycle wheels followed the traditions of carriage building: a wooden hub, a fixed steel axle (the bearings were located in the fork ends), wooden spokes and a shrink fitted iron tire. A typical modern wheel has a metal hub, wire tension spokes and a metal or carbon fiber rim which holds a pneumatic rubber tire. Hub A hub is the center part of a bicycle wheel. It consists of an axle, bearing (mechanical), bearings and a hub shell. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Biking
Mountain biking is a sport of riding bicycles off-road, often over rough terrain, usually using specially designed mountain bikes. Mountain bikes share similarities with other bikes but incorporate features designed to enhance durability and performance in rough terrain, such as air or coil-sprung shocks used as suspension, larger and wider wheels and tires, stronger frame materials, and mechanically or hydraulically actuated disc brakes. Mountain biking can generally be broken down into five distinct categories: cross country, trail riding, all mountain (also referred to as "Enduro"), downhill, and freeride. This sport requires endurance, core strength and balance, bike handling skills, and self-reliance. Advanced riders pursue both steep technical descents and high incline climbs. In the case of freeride, downhill, and dirt jumping, aerial maneuvers are performed off both natural features and specially constructed jumps and ramps. Mountain bikers ride on off-road trails su ...

Ross (bicycles)
Ross Bicycles Inc. manufactured over 15 million bicycles under the Ross brand between 1946 and 1988. The company began in Williamsburg, New York, United States, later moving its headquarters and manufacturing to Rockaway Beach, Queens. The headquarters remained in Rockaway when manufacturing was later moved to Allentown, Pennsylvania where Sherwood could focus on designing his high end Gran Eurosport model which featured synthetic grease, polished bearings, and 26 skip tooth front sprocket for friction reduction. Sherwood Ross, against the advice of his vice president Randy Ross, retooled the Allentown factory and experimented in unrelated bicycle endeavors involving government contracts. Randy Ross moved Ross bicycles manufacturing to Taiwan to keep margins competitive and bicycle manufacturing profitable, but Sherwood Ross's decision to keep the Allentown factory working on government contracts ultimately led to the company having to file for bankruptcy protection in 1988 Ross ...

Bicycle Suspension
Bicycle suspension is the system, or systems, used to ''suspend'' the rider and bicycle in order to insulate them from the roughness of the terrain. Bicycle suspension is used primarily on mountain bikes, but is also common on hybrid bicycles. Bicycle suspension can be implemented in a variety of ways, and any combination thereof: *Front suspension *Rear suspension *Suspension seatpost *Suspension saddle *Suspension stem (now uncommon) *Suspension hub Bicycles with only front suspension are referred to as hardtail and bicycles with suspension in both the front and rear are referred to as dual or full suspension bikes. When a bicycle has no suspension it is called rigid. Bicycles with only rear suspension are uncommon although the Brompton folding bicycle is equipped with rear only suspension. Although a stiffer frame is usually preferable, no material is infinitely stiff and therefore any frame will exhibit some flexing. Bicycle designers intentionally make frames in such ...

Red Bull Rampage
The Red Bull Rampage is an invitation-only freeride mountain bike competition held near Zion National Park in Virgin, Utah, United States, just to the north of Gooseberry Mesa. From 2001 till 2004, it was held off the Kolob Terrace Road, on the western boundary of Zion National Park. History The competition took place from 2001 till 2004. However, by 2005 the organisers canceled due to the increasing risk competitors were taking. After a three-year hiatus, Rampage returned in 2008 at a new venue. The organizers introduced wooden features for the 2008 event. Previously, the competition took place on a ''natural'' piste, meaning it was devoid of manmade features. The event usually occurs in October. Its format is similar to freestyle skiing and freestyle snowboarding, where competitors are judged on their choice of lines down the hill, their technical ability and the complexity and amplitude of tricks. Since its inception, Red Bull Rampage has become one of the biggest events in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downhill Mountain Biking
Downhill mountain biking (DH) is a style of mountain biking practiced on steep, rough terrain that often features jumps, drops, rock gardens and other obstacles. Jumps can be up to and including , and drops can be greater than . The rider commonly travels to the point of descent a ski lift or automobile, since the weight of the downhill mountain bike often precludes any serious climbing. In this context, the use of a motorized vehicle or device does not make DH a motorized sport. Riders must possess a unique combination of total body strength, aerobic and anaerobic fitness, and the acceptance of a relatively high risk of incurring serious permanent injuries. Downhill bikes are heavier and stronger than other mountain bikes and feature front and rear suspension with over 8 inches (20 cm) of travel, to glide quickly over rocks and tree roots. In competitive races, a continuous course is defined on each side by a strip of tape. Depending on the format, riders have ...

Freeride (mountain Biking)
Freeride is a discipline of mountain biking closely related to downhill biking, dirt jumping, freestyle motocross, and freestyle BMX. When riding a freerider one focuses on tricks, style, and technical trail features. Freeride is now recognized as one of the most popular disciplines within mountain biking. The term freeriding was originally coined by snowboarders, meaning riding without a set course, goals or rules on natural terrain. In mountain biking, it is riding trail with the most creative line possible that includes style, amplitude, control, and speed. Many in the cycling industry suggest that the Laguna Rads were the first to freeride, that is riding terrain that didn't already have an existing path or network of trails. History The original freeride bikes were modified downhill bikes that utilized gearing that enabled the rider to go up hills as well as down them. Modern freeride bikes are similar to downhill bikes, but feature slightly less suspension travel and ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Bicycle
The term road bicycle is used to describe bicycles built for traveling at speed on paved roads. Some sources use the term to mean racing bicycle. Other sources specifically exclude racing bicycles from the definition, using the term to mean a bicycle of a similar style but built more for endurance and less the fast bursts of speed desired in a racing bicycle; as such, they usually have more gear combinations and fewer hi-tech racing features. Certain of these bicycles have been referred to as 'sportive' bicycles to distinguish them from racing bicycles. Compared to other styles of bicycle, road bicycles share common features: * The tires are narrow, high-pressure ( or higher), and smooth to decrease rolling resistance * The handlebars are bent ("dropped") to allow the rider position to be leaned forward and downward, which reduces the forward vertical cross sectional area and thus highly reduces the air resistance * They usually use derailleur gears; however, single-speed ...

Specialized Stumpjumper
The Specialized Stumpjumper is a mountain bike produced by Specialized Bicycle Components. When it was first produced in 1981, the Stumpjumper was the first mass-production mountain bike. The Stumpjumper is still in production, although its design has changed significantly since it was first sold. Stumpjumpers have been raced professionally by riders including Christoph Sauser and Ned Overend. History Specialized started to produce the Stumpjumper in 1981, making it the first mass-production mountain bike. The first Stumpjumper was produced in Japan and was based on a design for a custom-made bike originally marketed by Tom Ritchey, Gary Fisher and Charles Kelly. Specialized's founder Mike Sinyard has explained that the company's aim was to "make a bike on a production basis but as though it was a custom bike". The first Stumpjumpers had welded steel frames because the lugged and brazed frames that designer Tim Neenan wanted to use were not available at the time. The original bike ...
