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] |
Shimano

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] |
Chainring
The crankset (in the US) or chainset (in the UK), is the component of a bicycle drivetrain that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel. It consists of one or more sprockets, also called ''chainrings'' or ''chainwheels'' attached to the '' cranks'', ''arms'', or ''crankarms'' to which the pedals attach. It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain. Parts Cranks The two ''cranks'', one on each side and usually mounted 180° apart, connect the bottom bracket axle to the pedals. Lengths Bicycle cranks can vary in length to accommodate different sized riders and different types of cycling. Crank length is measured from the center of the pedal spindle to the center of the bottom bracket spindle or axle. The larger bicycle component manufacturers typically offer ...

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 ...

Schwinn
The Schwinn Bicycle Company is an American company that develops, manufactures and markets bicycles under the eponymous brand name. The company was originally founded by Ignaz Schwinn (1860–1948) in Chicago in 1895. It became the dominant manufacturer of American bicycles through most of the 20th century. After declaring bankruptcy in 1992, Schwinn has since been a sub-brand of Pacific Cycle, owned by the Dutch Conglomerate (company), conglomerate, Pon Holdings. History Founding of Schwinn Ignaz Schwinn was born in Hardheim, Baden, Germany, in 1860 and worked on two-wheeled ancestors of the modern bicycle that appeared in 19th century Europe. Schwinn emigrated to the United States in 1891. In 1895, with the financial backing of fellow German American Adolph Frederick William Arnold (a meat packing, meat packer), he founded Arnold, Schwinn & Company. Schwinn's new company coincided with a sudden bicycle craze in America. Chicago became the center of the American bicycle industr ...

Raleigh Bicycle Company
The Raleigh Bicycle Company is a British bicycle manufacturer based in Nottingham, England and founded by Woodhead and Angois in 1885. Using Raleigh as their brand name, it is one of the oldest bicycle companies in the world.

Bike Trials Riding
Mountain bike trials, also known as observed trials, is a discipline of mountain biking in which the rider attempts to pass through an obstacle course without setting foot to ground. Derived from motorcycle trials, it originated in Catalonia, Spain as (from ''trial sin motor'', "motorcycle trials without an engine") and is said to have been invented by Pere Pi, the father of Ot Pi, a world champion motorcycle trials rider. Pi's father had wanted his son to learn motorcycle trials by practicing on an ordinary bicycle. Trials riding is an extreme test of bicycle handling skills, over many of obstacles, both natural and man-made. It now has a strong – though small – following worldwide, though it is still primarily a European sport. Skills taken from trials riding can be used practically on any bicycle for balance, for example controlled braking and track standing, or balancing on the bike without putting a foot down. Competition trial bikes are characterized by powerful brakes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
