side of the chainring or, in case of multi-sprocket chainring, on the outboard side of the largest chainring. Single-sprocket chainrings may have chain...

Freiburg Germany. This record was set on a bicycle setup with a 130-tooth chainring, weighing 20 kg and equipped with wooden rims.[verification needed] Cycling...

gear inches = drive wheel diameter in inches × number of teeth in front chainring number of teeth in rear sprocket {\displaystyle {\text{gear inches}}={\text{drive...

be used to take up chain slack. As well, finetuning the combination of chainring, cog, and chain length may suffice until the chain develops significant...

chain tension. A ghost or floating chainring is an additional chainring in the drive train between the driving chainring and sprocket. The top of the chain...

front chainring / number of teeth in rear sprocket). Gain ratio = (Radius of drive wheel / length of pedal crank) × (number of teeth in front chainring /...

18 mm (1⁄8 in). The chainring, sprocket and chain should all be the same width. Although a wider chain will work on a narrower chainring or sprocket, it is...

for the chainrings in order to reduce weight. This is done because the chain is shifted across the cassette much more often than the chainrings. This setup...

keep clothing from fouling the chain. See also Skirtguard, Bashguard. Chainring: (one of the) front gear(s), attached to a crank Chainset: see Crankset...

vertical and riders have little mechanical advantage. Biopace chainrings have a reduced chainring diameter coinciding with the cranks being horizontal. This...

possibility of the chain shifting past the smallest inner chainring, especially when the inner chainring is very small, even on bikes adjusted by professional...

"1x" drivetrains (pronounced "one-by"), simplifying the gearing to one chainring in the front and a wide range cassette at the rear, typically with 9 to...

levels. The inner level was driven by the chainring and the outer drove the rear cog. Instead of teeth, the chainring and cog had grooves into which the rollers...

fixed gear bicycle. The gearing of the chainring and sprocket are run at or near a one-to-one ratio, but the chainring may not have fewer teeth than the sprocket...

cyclo-cross bicycles are now set up with a single chainring and chain "drop" guards. A single chainring setup simplifies mechanics and reduces the chance...

BCD) chainring combination with a 12-25 to 12-30 cassette. Some riders opt to use a single chainring in the front (typically a 40-42 tooth chainring) while...

first to release a dedicated "one by" drivetrain with a single front chainring for road bikes. The company grew to become a cycling component brand,...

Typically the gearing has a triple chainring similar to mountain bicycles, whereas most road bicycles have only two chainrings. Raleigh's 1985 catalogue lists...

frame, which means that the rear sprocket is directly behind the front chainring. Chainline can also refer to the distance between a sprocket and the centerline...

called chainrings and sprockets to select a ratio. A dérailleur system normally has two dérailleurs, or mechs, one at the front to select the chainring and...
