   en.wikipedia.org/wiki/Bicycle_chain

   Bicycle chains Roller chain and sprocket. 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.

3. Crankset - Wikipedia

   en.wikipedia.org/wiki/Crankset

   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 crank lengths for adult riders from 165 to 180 mm (6.5 to 7.1 in) long in 2.5 mm (0.098 in) increments, with 170 mm (6.7 in) cranks being the most common size.

   List of bicycle parts by alphabetic order: Axle : as in the generic definition, a rod that serves to attach a wheel to a bicycle and provides support for bearings on which the wheel rotates. Also sometimes used to describe suspension components, for example a swing arm pivot axle

5. Bottom bracket - Wikipedia

   en.wikipedia.org/wiki/Bottom_bracket

   The plug is machined to accept a typical bottom bracket, but offset from the center of the plug, so that by rotating the plug, the location of the bottom bracket (and hence the chain tension) may be adjusted (fore and aft to tension the chain, the upper or lower eccentric position for a given chain length can be chosen to fine tune bottom ...

6. Bicycle gearing - Wikipedia

   en.wikipedia.org/wiki/Bicycle_gearing

   In the case of road bikes, this is usually around 670 mm. A 700c "standard" wheel has a 622 mm rim diameter. The final wheel diameter depends on the specific tire but will be approximately 622 mm plus twice the tire width. Front/rear measurement only considers the sizes of a chainring and a rear sprocket. Gear inches and metres of development ...

8. Derailleur - Wikipedia

   en.wikipedia.org/wiki/Derailleur

   Cage length, when combined with the pulley size, determines the capacity of a derailleur to take up chain slack. Cage length determines the total capacity of the derailleur, that is the size difference between the largest and smallest chainrings, and the size difference between the largest and smallest sprockets on the cogset added together. A ...
