Cadence is the rate at which a cyclist pedals or turns the bicycle’s cranks in a minute. It is measured in revolutions per minute (RPM).
A cadence sensor is a device that measures and records the rate at which a cyclist pedals or turns the bicycle’s cranks in revolutions per minute (RPM).
A carbon frame is the primary structural component of a bicycle’s frame, constructed primarily from carbon fiber composite materials. Carbon fiber is renowned for its exceptional strength-to-weight ratio, making it a popular choice for high-performance bicycles.
Carbon wheels refer to bicycle wheels with rims constructed primarily from carbon fiber composite materials. These wheels are known for their lightweight, aerodynamic properties, and stiffness, making them a popular choice for high-performance bicycles.
A cassette refers to the cluster of multiple sprockets or cogs that are attached to the rear wheel hub of a bicycle. These sprockets are an integral part of the bike’s drivetrain and are designed to work in conjunction with the chain and derailleurs to enable gear shifting.
A century ride in cycling is a long-distance bicycle ride covering 100 miles (160.9 kilometers) within a single day.
A chain catcher is a small device or component mounted on a bicycle’s front derailleur or seat tube to prevent the chain from dropping off the small chainring (the inner chainring) and falling between the small chainring and the frame when shifting to lower gears.
Chain drop refers to the unintentional disengagement of the bicycle chain from the chainring or cassette, resulting in a loss of power transmission and potential disruption to the rider’s pedaling motion.
Chain suck in cycling is a mechanical issue that occurs when the bicycle chain fails to disengage smoothly from the chainring during downshifting, leading to it getting stuck or sucked onto the chainring teeth.
A chain tool, or chain breaker, is a handheld tool designed to remove and install bicycle chains.
A chain whip is a tool used for holding the cassette or freewheel in place while removing or installing the lockring that secures it to the rear hub.
Chainline is the alignment of the bicycle chain with the chainring(s) and cassette or sprockets in the drivetrain.
A chainring is a key component of the bicycle’s drivetrain, typically attached to the crankset. It is a circular, toothed disc with various-sized teeth that engage with the bicycle chain.
Chainring bolts are small, threaded fasteners used to secure chainrings to the crankarms of a bicycle’s crankset.
A chainring guard, also known as a chainring protector or bash guard, is a protective component installed on a bicycle’s crankset.
Chainring ratio, often referred to as gear ratio, in cycling, is a numerical expression that compares the number of teeth on the front chainring(s) to the number of teeth on the rear cassette or sprockets.
Chainring size refers to the number of teeth on the front chainring(s) of a bicycle’s crankset.
The chainstay is a structural component of a bicycle frame that extends horizontally from the bottom bracket, near the pedals, to the rear dropout, where the rear wheel is attached.
A chainstay protector is a protective cover or guard typically made of durable rubber, neoprene, or adhesive-backed plastic.
A chamois (pronounced shammy) refers to a padded insert or lining that is an integral part of cycling shorts, bib shorts, or cycling tights.
Chamois cream, also known as chamois butter, is a specialized product used in cycling to reduce friction, chafing, and discomfort during long rides.
Cleats refer to small, often triangular or rectangular, pieces of hardware attached to the bottom of cycling shoes.
A climber is a cyclist who excels at riding uphill and is particularly skilled in mountainous or hilly terrain.
Clip-on bars, also known as clip-on aero bars or tri-bars, are a type of handlebar extension commonly used in road cycling, particularly during time trials and triathlons.
Clipless pedals are a bicycle pedal system designed to securely attach cycling shoes to the pedals.
Cleat play, also known as float or cleat float, is a term used to describe the degree of angular movement that a cyclist’s foot can have while engaged with clipless pedals.
A clutch refers to the mechanism found in the rear derailleur of a bicycle drivetrain. The clutch maintains tension in the derailleur’s chain, preventing excessive chain slack and reducing chain movement.
A cog refers to one of the individual-toothed wheels or sprockets that make up the rear cassette or freewheel of a bicycle.
A compact crankset is a specific type of bicycle crankset designed to provide a wider range of gear ratios, particularly lower gears, for easier climbing.
Crank length refers to the measurement of the metal arms that connect the pedals to the bicycle’s bottom bracket.
A crankset, also known as a chainset, is a major component of a bicycle’s drivetrain. It consists of two or more chainrings attached to crank arms.
A criterium, often called a crit, is a type of road cycling race held on a short, closed circuit typically ranging from 0.5 to 2 miles (0.8 to 3.2 kilometers) in length.
Crosswinds refer to wind blowing horizontally across the direction of travel.
Cyclocross, often abbreviated as CX, is a unique and challenging discipline that combines elements of road cycling, mountain biking, and cross-country running.
