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 Tire
A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for racing. Bicycle tires provide an important source of suspension, generate the lateral forces necessary for balancing and turning, and generate the longitudinal forces necessary for propulsion and braking. Although the use of a pneumatic tire greatly reduces rolling resistance compared to the use of a rigid wheel or solid tire, the tires are still typically, the second largest source, after wind resistance (air drag), of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle. Bicycle tires are also used on unicycles, tricycles, quadracycles, tandem bicycles, hand cycles, bicycle trailers, and trailer bikes. History The first bicycle "tires" were iron bands on the wooden wheels of velocipedes. These were fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Bicycle Gearing
Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, and the rate at which the drive wheel turns. On some bicycles there is only one gear and, therefore, the gear ratio is fixed, but most modern bicycles have multiple gears and thus multiple gear ratios. A shifting mechanism allows selection of the appropriate gear ratio for efficiency or comfort under the prevailing circumstances: for example, it may be comfortable to use a high gear when cycling downhill, a medium gear when cycling on a flat road, and a low gear when cycling uphill. Different gear ratios and gear ranges are appropriate for different people and styles of cycling. A cyclist's legs produce power optimally within a narrow pedalling speed range, or cadence. Gearing can be optimized to use this narrow range as efficiently as possible. As in other types of transmissions, the gear ratio is closely related to the mechanical ad ...

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] |
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 ...

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.

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 ...

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.
