Mountain Bikes
A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling (''mountain biking''). Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which often 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, wide handlebars to improve balance and comfort over rough terrain, and wide-ratio gearing optimized for topography, application (e.g., steep climbing or fast descending) and a frame with a suspension mechanism for the rear wheel. Rear suspension is ubiquitous in heavier-duty bikes and now common even in lighter bikes. Dropper seat 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 ... [...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.

Orbea Occam 2020
Orbea is a bicycle manufacturer based in Mallabia, Spain. It is part of the Mondragón Cooperative Corporation and Spain's largest bicycle manufacturer. Orbea manufactures and assembles bikes at their own factories in Spain and Portugal. History Orbea was founded in 1840 by brothers Juan Manuel, Mateo, and Casimiro Orbea in Eibar, Basque Country, Spain. Originally a rifle and gun producer, Orbea exited the gun business and began designing and producing bicycles as Orbea Bicycles in 1930. Orbea began participating in the Tour de France as early as 1934, with famous Spaniard Mariano Cañardo as the face of the Orbea road cycling team. In 1969, under dire financial circumstances, employees formed a co-operative and purchased Orbea from the Orbea family. The newly formed Orbea cooperative left Eibar the same year to nearby Mallabia, where their first dedicated bicycle factory was built. For the next several decades, the company would focus on producing leisure bikes for con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Gearing
Bicycle gearing is the aspect of a Bicycle drivetrain systems, bicycle drivetrain that determines the relation between the cadence (cycling), cadence, the rate at which the rider pedals, and the rate at which the drive Bicycle wheel, wheel turns. On some bicycles there is only one gear and, therefore, the gear ratio is Single-speed bicycle, fixed, but most modern bicycles have multiple gears and thus multiple gear ratios. A Shifter (bicycle part), 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 ... [...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 2 ... [...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 Union Cycliste Internationale (; UCI; ) is the world governing body for sports cycling and oversees international competitive cycling events. The UCI is based in Aigle, Switzerland. The UCI issues racing licenses to riders and enforces di .... 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 Wo ...

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 Ros ...

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 Charlie 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 origin ...

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, 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 and fixed-gea ...

Bicycle Tire
A bicycle tire is a tire that fits on the Bicycle wheel, wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for Wheelchair racing, racing. Bicycle tires provide an important source of Bicycle suspension, suspension, generate the lateral forces necessary for Bicycle and motorcycle dynamics#Balance, balancing and Bicycle and motorcycle dynamics#Turning, turning, and generate the longitudinal forces necessary for Vehicle propulsion, propulsion and Bicycle brake systems, 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 Drag (physics), 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, tricyc ...

Cruiser Bicycle
A cruiser bicycle, also known as a beach cruiser or (formerly) motobike, is a bicycle that usually combines balloon tires, an upright seating posture, a single-speed bicycle, single-speed drivetrain, and straightforward bicycle frame#Frame materials, steel construction with expressive styling. Cruisers are popular among casual bicyclists and vacationers because they are very stable and easy to ride, but their heavy weight and balloon tires tend to make them rather slow. Another common feature is their ability to be customized with accessories including fenders, lights and saddle bags. They are designed for use primarily on paved roads, low speeds/distances, and are included in the non-racing/non-touring class and heavyweight or middleweight styles of the road bicycle type. The bikes, noted for their durability and heavy weight, were the most popular bicycle in the United States from the early 1930s through the 1950s, and have enjoyed renewed popularity since the late 1990s. ...
