2. Bicycle brake - Wikipedia

   en.wikipedia.org/wiki/Bicycle_brake

   A hydraulic front disc brake. The disc is held by a six-bolt mount. The caliper is held attached to an IS fork mount via PM adapter. A disc brake consists of a metal disc, or "rotor", attached to the wheel hub that rotates with the wheel. Calipers are attached to the frame or fork along with pads that squeeze the rotors for braking.

3. Bicycle drivetrain systems - Wikipedia

   en.wikipedia.org/wiki/Bicycle_drivetrain_systems

   Major changes in bicycle form have often been initiated or accompanied by advances in drivetrain systems. Several early drivetrains used straight-cut gears that meshed directly with each other outside of the hub. [1] [2] Some bicycles have used a double-sided rear wheel, with different-sized sprockets on each side. To change gears, the rider ...

4. Cogset - Wikipedia

   en.wikipedia.org/wiki/Cogset

   On a bicycle, the cassette or cluster [1] 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 ...

5. Flip-flop hub - Wikipedia

   en.wikipedia.org/wiki/Flip-flop_hub

   DK Bicycles introduced the Dual Drive hub back in the early 2000s which is a BMX Left/Right drive flip flop hub with the smaller sized metric (30 mm x 1 mm) BMX threads for 13T-15T freewheels, but also includes two threaded adapters, one left and one right, threaded inside to match the smaller metric threads and threaded on the outside with ...

6. Freehub - Wikipedia

   en.wikipedia.org/wiki/Freehub

   A set of sprockets (called a "cassette") is mounted onto a splined shaft of the freehub to engage the chain. The ratcheting mechanism is a part of the hub, in contrast to a freewheel, an older technology, which contains both the sprockets and a ratcheting mechanism in a single unit separate from the hub. In many high-end and midrange bicycles ...

8. Eccentric (mechanism) - Wikipedia

   en.wikipedia.org/wiki/Eccentric_(mechanism)

   Eccentric bottom bracket on a Burley tandem bicycle held in place with two set screws. The term is also used to refer to the device often used on tandem bicycles with timing chains, single-speed bicycles with a rear disc brake or an internal-geared hub, or any bicycle with vertical dropouts and no derailleur, to allow slight repositioning, fore and aft, of a bottom bracket to properly tension ...

9. Disc brake - Wikipedia

   en.wikipedia.org/wiki/Disc_brake

   Close-up of a disc brake on a Renault car. A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc (sometimes called a [brake] rotor) [1] to create friction. [2] There are two basic types of brake pad friction mechanisms: abrasive friction and adherent [further explanation needed] friction. [3]
