Mountainbike
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 othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sprocket
A sprocket, sprocket-wheel or chainwheel is a profiled wheel with teeth that mesh with a roller chain, chain, Caterpillar track, track or other perforated or indented material. The name 'sprocket' applies generally to any wheel upon which radial projections engage a chain passing over it. It is distinguished from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth except for timing pulleys used with toothed belts. Sprockets are used in bicycles, motorcycles, continuous track, tracked vehicles, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track, tape etc. Perhaps the most common form of sprocket may be found in the bicycle, in which the pedal shaft carries a large sprocket-wheel, which drives a chain, which, in turn, drives a small sprocket on the axle of the rear wheel. Early automobiles were also largely dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Fork
A bicycle fork is the part of a bicycle that holds the front wheel. A fork typically consists of two ''blades'' which are joined at the top by a fork ''crown.'' The crown is often at the front. Most suspension forks have an arch connecting the two side of the lowers (the part connected to the axle.) It is often in front of the stanchions (shaft the lowers slide on) but not always. Above the crown, a ''steerer tube'' attaches the fork to the bicycle and the handlebars (via a stem) allowing the rider to steer the bicycle. The steerer tube of the fork interfaces with the frame via bearings called a headset mounted in the head tube. At the bottom of the fork, ''fork ends'' hold the wheel. Usually, either the axle is bolted to the fork, or a ''quick release skewer'' passes through a hollow axle, clamping the axle to the fork. The term ''fork'' is sometimes also used to describe the part of a bicycle that holds the rear wheel, which on 19th century ''ordinary'' or ''penny-farth ...

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] |
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 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UCI Mountain Bike World Cup
The UCI Mountain Bike World Cup is a multi-round mountain bike racing series that is sanctioned by the Union Cycliste Internationale. The first World Cup series – which was composed of cross-country events – was held in 1989. The Downhill World Cup was inaugurated two years later, and the Dual Slalom World Cup was launched in 1998. The dual-slalom format – which involved knock-out heats with two riders on the parallel courses in each heat – evolved into four-cross (with four riders on a single course per heat) in 2002 before being dropped after the 2011 season. Riders win points according to their placing in each event. The reigning series leaders in each class are identified by a special jersey. The UCI Mountain Bike World Cup is broadcast live and globally on Red Bull TV. The replacement world series for 4X World Cup is the 4X Pro Tour and for XCM World Cup is UCI MTB Marathon series. Overall series winners Cross-country (XCO) Men * Medals: Women * Meda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

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-spee ...
