Honda RN-01 G-cross
The Honda RN-01 G-Cross is a mountain bike produced by Honda specifically for downhill racing events. Honda is not a manufacturer of bicycles and this bike is not commercially available to the general public. It was introduced in the 2004 racing season by the ''Team G Cross Honda'' who competed in the NORBA and Mountain Bike World Cup points series races. What sets it apart from most other bicycles is the fact that it was developed specifically for race use by the Honda team using many purpose made components not commercially available. It is also different in that it uses an internal gearbox instead of external (derailleur) gearing system, which although not unique to this bicycle, is quite rare. The gearbox on the RN-01 is specific because it is not a classic gearbox such as the Rohloff Speedhub, for example. Inside the gearbox there is a classic derailleur, a cassette and a chainring. The freewheel is not placed on the rear wheel but in the bottom bracket, so the chain is const ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Downhill Cycling
Downhill mountain biking (DH) is a style of mountain biking practiced on steep, rough terrain that often features Glossary of cycling#gap jump, jumps, Glossary of cycling#drop, drops, Glossary of cycling#rock garden, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle
A bicycle, also called a pedal cycle, bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century, more than 1 billion were in existence. These numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, bicycle racing, and bicycle stunts. The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Red Bull TV is a global multi-platform channel owned by Red Bull GmbH, distributed digitally on connected TVs, smartphones, tablets, and on its website. The channel is available globally. Programming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derailleur
Shimano 600 front derailleur (1980) A derailleur is a variable-ratio bicycle gearing system consisting of a chain, multiple sprockets of different sizes, and a mechanism to move the chain from one sprocket to another. Modern front and rear derailleurs typically consist of a moveable chain-guide that is operated remotely by a Bowden cable attached to a shifter mounted on the down tube, handlebar stem, or handlebar. When a rider operates the lever while pedalling, the change in cable tension moves the chain-guide from side to side, "derailing" the chain onto different sprockets. Etymology ''Dérailleur'' is a French word, derived from the derailment of a train from its tracks. Its first recorded use was 1930. History A modern road bicycle drivetrain with front and rear derailleurs Various derailleur systems were designed and built in the late 19th century. One example is the Protean two-speed derailleur available on the Whippet safety bicycle. The French bicycle tou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Rohloff
Rohloff AG is a German company from Fuldatal near Kassel that manufactures hub gears, bicycle chains and tools that are known for their durability and high performance. The company’s logo is a black silhouette of a raven on a yellow background. History Rohloff AG was founded in 1986 and began by producing a high-tech and very expensive bicycle chain, the SLT 99. Sales of this chain generated revenues of €1m in 1991, and approximately €0,5m annually from 1992-1998. Development of Rohloff Speedhub 500/14 While at the Tour de France road race in France in 1994, the Rohloffs went bicycling on the beach in France. The bikes got stuck in the sand, and the primitive derailleur gear systems would not work. This triggered Bernhard Rohloff to develop a new internally geared hub. On the 1996 IFMA in Cologne, Rohloff announced a 14-speed gear hub with a weight of 1700 grams. At the time, the gear hub with the greatest number of speeds was the fragile 3700 gram 12 speed Sa ...

Front Freewheel
The Shimano Front Freewheel (FFS) was a proprietary bicycle drivetrain design of the 1970s that placed a freewheel between the pedal cranks and the front chainrings — enabling the rider to shift gears while coasting. FFS rear freewheel is different than a standard freewheel because it's "stiff" with more friction than a normal rear freewheel. It will slip if necessary however, to stop the chain in the event of, for example, a clothing tangle — which could otherwise lead to injuries of the leg by the drivetrain, crashing of the bicycle, or both. FFS marketing followed Shimano's then-current path of beginning with lower-cost implementations of the system using low tech and usually heavier materials. The resulting system was substantially heavier than the standard freewheel and, in any event, did not penetrate the market noticeably, although Panasonic, Ross, Schwinn, and Raleigh briefly equipped bicycles with FFS. The late Sheldon Brown called FFS a "solution in search ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
