<span class="mw-page-title-main">Derailleur</span> Variable-ratio transmission system commonly used on bicycles

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.

<span class="mw-page-title-main">Hub gear</span> Device for changing gear ratio on bikes

A hub gear, internal-gear hub, internally geared hub or just gear hub is a gear ratio changing system commonly used on bicycles that is implemented with planetary or epicyclic gears. The gears and lubricants are sealed within the shell of the hub gear, in contrast with derailleur gears where the gears and mechanism are exposed to the elements. Changing the gear ratio was traditionally accomplished by a shift lever connected to the hub with a Bowden cable, and twist-grip style shifters have become common.

Shimano, Inc., originally Shimano Iron Works (島野鐵工所) and later Shimano Industries, Inc. (島野工業株式会社), is a Japanese multinational manufacturing company for cycling components, fishing tackle and rowing equipment, who also produced golf supplies until 2005 and snowboarding gear until 2008. Named after founder Shozaburo Shimano and headquartered in Sakai, Osaka Prefecture, the company has 32 consolidated and 11 unconsolidated subsidiaries, with the primary manufacturing plants based in Kunshan (China), Malaysia and Singapore.

Campagnolo is an Italian manufacturer of high-end bicycle components with headquarters in Vicenza, Italy. The components are organised as groupsets (gruppi), and are a near-complete collection of a bicycle's mechanical parts. Campagnolo's flagship components are the Super Record, Record, and Chorus groupsets with all three representing their recent shift to 12-speed drivetrains. Super Record and Record are the top groupsets, followed by Chorus, Potenza, Centaur and Veloce. Campagnolo also produces aluminum and carbon wheels, as well as other components.

<span class="mw-page-title-main">Bicycle chain</span> Roller chain that transfers power from the pedals to the drive-wheel of a bicycle

A bicycle chain is a roller chain that transfers power from the pedals to the drive-wheel of a bicycle, thus propelling it. Most bicycle chains are made from plain carbon or alloy steel, but some are nickel-plated to prevent rust, or simply for aesthetics.

<span class="mw-page-title-main">Bottom bracket</span> Bicycle component

The bottom bracket on a bicycle connects the crankset (chainset) to the bicycle and allows the crankset to rotate freely. It contains a spindle to which the crankset attaches, and the bearings that allow the spindle and crankset to rotate. The chainrings and pedals attach to the cranks. Bottom bracket bearings fit inside the bottom bracket shell, which connects the seat tube, down tube and chain stays as part of the bicycle frame.

<span class="mw-page-title-main">ZF Sachs</span> German family business

ZF Sachs AG, also known as Fichtel & Sachs, was founded in Schweinfurt in 1895 and was a well-known German family business. At its last point as an independent company, the company name was Fichtel & Sachs AG.

The Birdy is a folding bicycle designed by Riese und Müller in Germany and produced by Pacific Cycles in Taiwan. As of 2010 over 100,000 had been sold. Three distinct models have been marketed, in addition to some specialist variations, with the third (Mk3) introduced in July 2015.

SRAM LLC is a privately owned bicycle component manufacturer based in Chicago, Illinois, United States, founded in 1987. SRAM is an acronym comprising the names of its founders, Scott, Ray, sAM,. The company produces a range of internally developed cycling components, including Grip Shift, separate gravel, road, and mountain drivetrains from 7 to 12 speed. SRAM developed the Eagle line of mountain bike specific drivetrain components intended to improve shifting performance. SRAM was also the first to release a dedicated "one by" drivetrain with a single front chain-ring.

<span class="mw-page-title-main">Cogset</span> Set of sprockets attached to the rear wheel hub of a bicycle

On a bicycle, the cassette or cluster is the set of multiple sprockets that attaches to the hub on the rear wheel. A cogset works with a rear derailleur to provide multiple gear ratios to the rider. Cassettes come in two varieties, freewheels or cassettes, of which cassettes are a newer development. Although cassettes and freewheels perform the same function and look almost the same when installed, they have important mechanical differences and are not interchangeable.

<span class="mw-page-title-main">Shifter (bicycle part)</span> Bicycle component

A bicycle shifter or gear control or gear levers is a component used to control the gearing mechanisms and select the desired gear ratio. Typically, they operate either a derailleur mechanism or an internal hub gear mechanism. In either case, the control is operated by moving a cable that connects the shifter to the gear mechanism.

<span class="mw-page-title-main">Hub dynamo</span> Electrical generator in a bicycle wheel

A hub dynamo is a small electrical generator built into the front hub of a bicycle wheel that is usually used to power lights. Often the hub "dynamo" is not actually a dynamo, which creates DC, but a low-power magneto that creates AC. Most modern hub dynamos are regulated to 3 watts at 6 volts, although some will drive up to 6 watts at 12 volts.

<span class="mw-page-title-main">Kronan (company)</span>

Kronan bicycles are marketed by Kronan Trademark AB, also known as Kronan AB. Kronan AB was established in June 1997 by three former-students, John Wahlbäck and the Avander brothers, Henry and Martin. In autumn 2003 the company was bought by the Brunstedt family with Mary Brunstedt as the company's current CEO.

<span class="mw-page-title-main">Rohloff</span> German manufacturer of bicycle components

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.

<span class="mw-page-title-main">Electronic gear-shifting system</span> Method of changing gears on a bicycle

An electronic gear-shifting system is a method of changing gears on a bicycle, which enables riders to shift with electronic switches instead of using conventional control levers and mechanical cables. The switches are connected by wire or wirelessly to a battery pack and to a small electric motor that drives the derailleur, switching the chain from cog to cog. An electronic system can switch gears faster and, because the system does not use Bowden cables and can calibrate itself, it may require less maintenance.

<span class="mw-page-title-main">Shimano Alfine</span>

Alfine is the name of a comfort and urban oriented product series by Shimano. It is mainly known for internally geared hubs, but includes also hydraulic disc brakes and levers, chain tensioners, dynamo hubs, cranksets, shift levers, and complete wheels.

<span class="mw-page-title-main">Shimano Nexus</span>

Shimano Nexus is a brand of bicycle components which includes products such as epicyclical gear hubs, cranksets, shifters, brake levers, hub brakes, hub dynamos, and a CPU for automatically changing gears. The series is primarily aimed at the "comfort" market such as urban commuters and tourers, and as such is not made to withstand the rigours of off-road or mountain biking. The free-wheeling Nexus internal gear hubs are compatible with Shimano's "roller brake", its version of a drum brake, but not with the Shimano disc brakes used with the higher-end Shimano Alfine internal gear hubs.

The SRAM i-Motion series of products is a sport, urban, and trekking oriented product series developed and manufactured by SRAM Corporation. Branded i-Motion are internally geared hubs, shift levers, and dynamo hubs. Related to the i-Motion series are also changeable free or fixed single speed hubs, hybrid epicyclic and derailleur gear hubs, and hydraulic disc brakes. The i-Motion series of products were developed at SRAMs Schweinfurt R&D and manufacturing plant in Germany, formerly of Sachs.

SRAM G8 is an internally geared hub for bicycles developed and manufactured by the American cycling component manufacturer SRAM Corporation. It entered production in 2013.

Kindernay is a brand of hub gears manufactured by the Norwegian start-up company CA Technology Systems. They use hydraulic gear levers and are manufactured in Oslo, Norway. Their system differs from their competitors by having a modular design called Swap Cage where the gear mechanism can be easily separated from the hub housing, so that the end-user can use the hub gear with several different wheel sets. This could make it easier and more economical to change wheel sets to adapt the bike for different seasons or roads, or so that wheels can be easily changed between bikes. The hubs are assembled at Kindernay's factory in Oslo by hand, but in the long term it is planned that production will be automated and assembled by robots.
