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.
When "safeties" replaced "ordinaries", chains and sprockets allowed small wheels to be turned faster than the pedal cranks. As result, a 28-inch wheel could be made to move a bicycle at the same speed as a 60-inch wheel. Such a bicycle was then said to be geared at 60 gear inches and pedalled similar to an ordinary with a 60-inch wheel.

16 tooth sprocket. Do = Sprocket diameter. Dp = Pitch diameter A sprocket and roller chain. A sprocket, [1] sprocket-wheel [2] or chainwheel is a profiled wheel with teeth that mesh with a chain, rack or other perforated or indented material. [3] [4] The name 'sprocket' applies generally to any wheel upon which radial projections engage a chain ...
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 ...
In 1991, a two-wheel drive bicycle was marketed under the Legacy name. It used a flexible shaft and two bevel gears to transmit torque from the rear wheel, driven by a conventional bicycle chain with derailleurs, to the front wheel. [11] In 1994, Steve Christini and Mike Dunn introduced a two-wheel drive option. [12]
Chainrings (also called "chain rings", [11] "chainwheels" or "sprockets", although sprocket is used this way mostly in the BMX community [3]) engage the chain to transfer power to the (usually rear) wheel. They usually have teeth spaced to engage every link of the chain as it passes over; however, in the past, some designs (called skip-tooth or ...
