Off-road tire, or a bicycle tire designed to function well for varied terrain and uses.
All-rounder
A racing cyclist who excels in both climbing and time trialing, and may also be a decent sprinter. In stage races, an all-rounder is likely to place well in the general classification. All-rounders are usually Team Leaders in both stage races and classics cycle races. The term all-rounder can also mean a bicycle designed to function well for varied terrain and uses.[9]
A bicycle race typically organized by bicycle messengers or couriers. Alleycat races seek to replicate some of the duties that a working messenger might encounter during a typical day. The races usually consist of previously undisclosed checkpoints, which are listed on a manifest, that a racer will have to go to; once at the checkpoint, the racer will have their manifest updated. First racer to return with a completed manifest wins. Alleycats were first formalized in Toronto, Ontario, Canada, in 1989; however, messengers have been racing against each other for much longer. Recently,[when?] with the boom in urban cycling, many non-messengers have been participating in and organizing alleycat races.[10]

A drop on a downhill section of a race course
Drop
(or drop-off) A steep section, or sudden drop on a mountain bike trail.[39]
To be dropped is to be left behind a breakaway or the peloton for whatever reason, usually because the rider cannot sustain the tempo required to stay with the group. To drop someone is to accelerate strongly with the intent of causing following riders to no longer gain the benefit of drafting.[32]:238
(or "Drops") The lower part of the handlebars on a road bike; they run parallel with the top-tube.
(French) A line of riders seeking maximum drafting in a crosswind, resulting in a diagonal line across the road.[7][22]

Espoir
(French: hope) Age class for riders 19 to 22.[41] Also called U23.[42]
The fall line describes the direction on a mountain or hill which is most directly downhill. A trail is said to follow the "fall line" if it generally descends in the most downward direction, rather than traversing in a sideways direction.[43]
False flat
A low-gradient climb, usually occurring partway up a steeper climb. So-called because while it may look deceptively flat and easy (especially after the steep climb preceding it), it is still a climb.[44]
Fast finisher
A rider who has superior sprinting speed over the last few hundred meters of a race.[45]
Feed zone
In road bicycle racing, a location along the course of a long race where team personnel hand musettes containing food and beverages to passing riders. In mountain bicycle racing, a limited section of the course in which riders may accept food from non-racing assistants. Sometimes this is combined with the technical assistance zone if one exists.[22]
A red flag displayed with one kilometer remaining from the finish line of a race. Usually suspended over the road.[19]
Floating disc rotors
In a two piece disk brake rotor, floating rotors keep the braking surface cooler. A steel braking surface is riveted to an aluminium piece. When a rotor is subjected to serious heat, it expands.
Follow a wheel
The ability to follow a wheel is the ability to match the pace of riders who are setting the tempo. Following is easier than pulling or setting the tempo and the term can be used in a derogatory manner, e.g. "S/he only ever followed".[19]
The bicycle frame plus the front fork.[48] or a bicycle frame with shock and fork included, or just the including the shock if it's a full suspension frame.

Alternatively wanton and furious cycling or furious riding; a statutory offence in England and Wales and Northern Ireland applied to cyclists who cycle over the national speed limit.[50]
Gap
A distance between two or more riders large enough for drafting to no longer be effective. Also used as a verb (US English); for example: "Contador has gapped Armstrong!". It's much easier for a stronger rider to pull ahead of others once a gap has been achieved; without a gap, the others can draft along using significantly less power to sustain the same speed as the rider in front. While gaps are usually achieved through attacks, on mountain climbs, where slower speeds means the advantage of drafting is much less significant, riders are often gapped who simply cannot maintain the tempo of the faster riders.[25]
A gap jump
Gap jump
A jump with separate take-off and landing zones, having a "gap" between the ramps.[51]
G.C.
Abbr.: general classification. The timing splits used to determine who is winning in a stage race, and the overall position of riders relative to the leading rider. Riders can attack in stage races for time rather than winning the day's stage. They are said to be "riding for G.C.". In such circumstances alliances can form where some riders in a breakaway will work to help others win the day's stage despite not contesting the finish as the overall gap the breakaway gains helps them "on G.C."[22][25]
Granny Gear
Two meanings related to each other:
The lowest gear ratio on a multi-speed derailleur bicycle; smallest chainring in front and the largest at the back.
The smallest chainring on a crank with triple chainrings.[12][52]

The keirin is a 2000-meter track event where the riders start the race in a group behind a motorised derny. The derny paces the riders for 1400 meters and then pulls off the track, at which time the cyclists begin a sprint to the finish line. Keirin racing has traditionally been practised in Japan, where it has been a professional sport for over 20 years, and only in which pari-mutuel betting on the riders is permitted.
Kick
Accelerating quickly with a few pedal strokes in an effort to break away from other riders (e.g. "Contador kicks again to try to rid himself of Rasmussen")[67]
French for "red lantern", as found at the end of a railway train, and the name given to the rider placed last in a race.[12][19]
Lead out
Sprinting technique often used by the lead out man where the rider will accelerate to maximum speed close to the sprint point with a teammate, the sprinter, drafting behind, hoping to create space between the sprinter and the pack. When the lead out man is exhausted, they will move to the side to allow their teammate to race in the sprint. Often a line of lead out men will be used to form a lead out train to drive the speed higher and higher (and to reduce the chances of other riders attacking) over the closing stages of a race. The purpose of a lead out is for the sprinter to achieve high speed at the sprint approach using as little of their own energy as possible, so they have as much energy as possible for the final sprint.[7][19]
Leech
A rider who drafts behind others to reduce their effort, but does not reciprocate. Also wheelsucking.[68]

Limit
(Australian) First riders to depart in a handicap race.[12]
A mass-start track event comprising teams of two riders per team. It is similar to a team points race, as points are awarded to the top finishers at the intermediate sprints and for the finishing sprint. Only one of the two team riders is racing on the track at any one time, riding for a number of laps, and then exchanging with their partner by a hand sling. The name comes from the original Madison Square Garden, which was constructed as a velodrome.[69][70]

The shoulder strap is placed over the head and one shoulder, the contents are then removed and placed into jersey pockets or bottles (bidons) are placed into bottle cages. The bag is then discarded.[79]
A rider who is riding at maximum speed. When riding at maximum power output, a road racer often perches on the front tip of the saddle (seat), where the shell of an old-style leather saddle would be attached to the saddle frame with a rivet.[67]

Poursuivant
From French, literally "pursuer". A cyclist or group of cyclists who are separated from and behind the leader(s) (tête de la course) but in front of the main group. (peloton). This usually occurs when a small number of riders attempt to catch up to the leaders, either to join with them or to "bring them back to the pack" by encouraging the main group to chase them down.[19]
Prime
Primes (pronounced preems, after the French word for "gift") are intermediate sprints within a race, usually offering a prize or points. Primes are a way to encourage more competitive riding, and also an opportunity for companies to gain publicity by sponsoring a prime. In a criterium, a bell is sounded on the lap preceding the prime sprint at the appropriate line for that prime sprint. The line used for prime sprints need not be the same as the start or finish line. Primes may be either predetermined for certain laps or spontaneously designated under the supervision of the Chief Referee. Lapped riders are not eligible for primes except in the following situation: when a breakaway has lapped the main field, riders in the main field and the breakaway riders are then both eligible for primes.[22]
Prologue
An individual time trial of usually less than 8km (5mi) before a stage race, used to determine which rider wears the leader's jersey on the first stage.[32]
A track consisting of rollers and banked turns designed to be ridden without pedalling. Momentum is created by "pumping", movements of the body up and down.[90]
A type of road bicycle racer who specializes in rolling terrain with short but steep climbs. Ideal races for this type of rider are the one-day classics in spring. These races are characterized by hills that are a 10–20% grade and 1–2km long; examples include the Liège–Bastogne–Liège, the Mur de Huy in the Flèche Wallonne and the Manayunk Wall in the Philadelphia International Championship. The physique of this type of rider allows them to escape from the peloton through quick bursts usually with the assistance of a teammate. Examples of such racers include Philippe Gilbert, Paolo Bettini, Danilo Di Luca and Peter Sagan, who are able to sprint their way up the shorter climbs to win a stage or a single-day race.[91][92][93]
Queen stage
The stage of a multi-day road race which is deemed the hardest, most demanding and most prestigious stage of the race.[72][94] Derived from the French étape reine.[95]
Queen of the Mountains (or "QOM")
The title given to the best female climber in a road race.
The fastest female rider on a segment (such as on the ride-tracking web site Strava).
A long-distance discipline of cycling where riders attempt courses from 200 to over 1200km, collecting stamps at controls with the clock running constantly. Every participant finishing within minimum and maximum time limits is considered a winner regardless of finishing order. Riders may ride in a group or solo as they please, and are expected to be self-sufficient between controls. Randonneuring is not regulated by UCI.
A bicycle or tricycle where the rider is placed in a laid-back position, feet first and sitting in a seat instead of on a saddle. Usually used for ergonomics or aerodynamics. All world land speed records are held by (enclosed) recumbent bicycles, but these bikes are not allowed in races governed by the UCI.[97]
An experienced rider who organizes a team's riders in a road race, including making tactical decisions and improvising new tactics when pre-race plans are overtaken by events on the road. They are the key link between the directeur sportif and the rest of the team. Road captains are normally selected on a race-by-race basis depending on the demands of the event and their relationship with the team leader. Notable road captains in recent years include Bernhard Eisel, Luca Paolini, Mick Rogers and David Millar.[100][101]

Rollers
A type of trainer composed of rolling cylinders under the rear wheel linked to a single rolling cylinder under the front wheel which allow the rider to practice balance while training indoors.[102]
Rotating weight
Mass that is rotating while the bike is moving, which is a form of inertia. A bicycle wheel can be approximated as a hollow cylinder with most of its mass near the rim. The rotation of the cranks, hubs, and other parts are less significant because both their radius and rotational speed are smaller. Reducing the rotating weight with lighter wheels and tires will permit faster acceleration and braking (or the same acceleration and braking with less energy).[103]
How much a bike sinks into its travel just by having body weight on it.[104]
Sag wagon

A mountain bike trail designed for a single line of riders.
Sit-on and Sit-in
To ride behind another rider without taking a turn on the front (thus tiring the lead rider), often in preparation for an attack or sprint finish. "Sitting in the wheels" is to take an easy ride drafted by the peloton or gruppetto. Often a strategic decision to save energy in races.[7]
Skinny
A narrow beam to be ridden over lengthwise, as a test of a rider's skill. A skinny can be of various widths (almost as narrow as a bike tire, and up to 20cm wide) and various lengths (from one to several meters). Some may also "neck-down" to successively thinner widths, and may also have steps, and be on an incline (up or down). They may be close to the ground, or in some cases dangerously high, and even span small creeks or other obstacles.[51]
Soigneur
French for "healer". A non-riding member of a team whose role is to provide support for the riders, possibly including transportation and organization of supplies, preparation of the team's food, post-ride massages and personal encouragement.[19]
Sportive bicycle
Also known as comfort or endurance bicycle. A type of racing bicycle intended for less competitive cyclosportive and long-distance riding. Typically features more upright riding geometry, higher handlebar position, longer wheelbase, and disk brakes.[107][108]
Rider with the ability to generate very high power over short periods (a few seconds to a minute) allowing for great finishing speeds, but usually unable to sustain sufficiently high power over long periods to be a good time triallist. Sprinters are usually too big to have a high enough power-to-weight ratio to be good climbers.[19]
Squirrel
A cyclist who has a tendency to swerve unexpectedly and maintain inconsistent speed. Considered dangerous to follow at close range for the purpose of drafting.[22]
An amateur rider, who is taken in by a professional team during the season. This lets the rider get some experience at riding a few pro races, and the team gets a chance to assess the abilities of the rider.[67]
The component that attaches the handlebars to the steer tube of the bicycle. They come in two major types, quill and threadless. The angle and length plays a major part in how the bicycle fits the rider.[7]
Sticky bottle
A technique often used by the rider who takes food and water from the team car during a race. The car occupant continues to hold the bottle after handing it to the rider, effectively dragging the athlete. This concerted act gives the cyclist a moment to relax. Usually tolerated by the race commissaire if the bottle is held for 1–2 seconds, but may result in a sanction (such as disqualification) if abused.[110][111]
A race that ends at the top of a mountain climb. Such stages favour the climbers and are normally decisive in major stage races like the Giro d'Italia and the Tour de France.[112]

A group of cyclists working together as part of a competition.
Team time trial
Riders start in groups or teams, usually of a fixed size. The time of the nth rider of a team counts for the classification for each team member. In the 2009 edition of Tour de France, riders who are dropped from their team's group would be scored with their own time, instead of the team time.[22]
Technical
A description of a trail or trail feature requiring "technical" skill to ride well. A technical climb, for example, may have an uneven surface and tight turns making the ascent challenging without well developed mountain biking skills.[114]
Technical Assistance Zone
A designated section along the course of a mountain bike or cyclocross race along which riders are allowed to accept technical assistance (tools, spare parts, or mechanical work) from another person. In cyclocross racing the technical assistance zone is called the "pit". Not all mountain bike races contain a technical assistance zone, instead requiring riders to carry whatever tools and spare parts they may need. A rider accepting technical assistance outside of the designated zone risks disqualification.[115]
A TTF consisting of a wood drop followed quickly by a banked berm
TTF
Technical Trail Feature, a feature often found on mountain biking trails designed as a challenge or test of a rider's skill. It can include log piles, log rides, wall rides, jumps, skinnies, and so forth. Difficult TTFs may have an optional bypass.[51]
Tempo
Steady pace at the front of a group of riders. A relatively fast tempo can be used by a group or team to control the peloton, often to make up time to a break. The group will ride at the head of the bunch and set a fast enough pace to stretch the peloton out (also known as stringing out) and discourage other riders from attacking. Setting a slower tempo can be done for the purpose of blocking.[116] A tempo is also a type of track race where two points are awarded to the first person to cross the line each lap, and one point is awarded to the second person to cross the line each lap.[117]
Tempo pace
A level of exertion just below the rider's anaerobic threshold. Used as a reference point in training, this is the highest level of exertion that a given rider can sustain.[118]
Tête de la course
From French, literally "head of the race". The leading cyclist or group of cyclists, when separated from (in front of) the peloton.[119] See Cabeza de carrera.
A race against the clock where riders are started separately (ranging from 30 seconds to 5 minutes apart). The winner of the race is determined by the fastest person across the course. No drafting may be employed in a time trial as it is a solo race event.[7]
A rider that can generate relatively high power over long periods of time (5 minutes to an hour or more) in a race against the clock.[120]
To Stick The Knife In
To finish off a group of riders who are about to crack. The perpetrator knows (or guesses) they have better overall energy than their competitors, presumably after making them suffer with numerous accelerations. The ensuing violent acceleration, which results in dropped competitors, is referred to as "sticking the knife in".[121]
Track
An oval cycling track for races, banked at up to 50 degrees. Cycling tracks are usually indoors. Bicycling or cycle tracks are also called velodromes.[72] An Olympic track is generally 250 m long.[122]
Train
A method in stage races to get a sprinter to the front of a bunch sprint and launched. The sprinter's team riders will form a line, usually within 5k of the finish, and take turns to build up speed. The last rider in the train will be protected (drafting) until a short distance from the finish. Perfected by HTC and Mark Cavendish.
A piece of equipment that a bicycle stands on so that the rear wheel can spin while the bicycle is stationary, allowing stationary riding. These are usually used when the conditions outside are bad.[123]
Also known as an old-school sprinter. A rider who excels primarily in sprint finishes on flat to mildly uphill terrain. Often too heavy to compete in longer or steeper uphill courses.[124]
Tubular tyres have the inner tube permanently stitched inside the casing. They are held in place using glue or glue-tape, and are affixed to rims which lack the sidewalls characteristic of a hook-bead rim. Tubulars take very high pressure which reduces their rolling resistance, and can result in wheelsets that are lower in overall weight than comparable clincher wheels. They can also be ridden at lower pressures than clinchers without the risk of pinch flats, because of the shape of the rim. This makes them well-suited to cyclo-cross, especially in muddy conditions where low tire pressures are used. Also called sew-ups, tubies, or tub.[7]
Turbo-trainer
A trainer that provided resistance when peddling a bike, fixed in place. Often resistance is provided by a fan assembly or a magnet. See Bicycle trainer.[125]
Turn
A turn is a rider sharing the workload on a pace line.[72] In a breakaway, the riders expect to share the work equally in "turns". A rider who does not take their turn is said to be "sitting on".[126]
Alternatively known as a city bike, a bicycle that is designed to be ridden on the road sometimes utilizing components of a mountain bike and in most cases, hydraulic disc brakes; similar to a hybrid bicycle.[127]
USS
Under seat steering, a steering configuration on recumbent bicycles where the handlebar goes under the seat, like on an office chair.[62]
A banked turn which becomes vertical or nearly vertical (i.e. a "wall"). A skilled rider on a wall at high speed will lean sharply, and in some cases will almost become horizontal while on the wall. A wall-ride can be integral with the trail (formed of dirt or rock), or be constructed of wood.[51]
Water carrier
Referred to in French as a 'Domestique'. A member of a team who chases down competitors and tries to neutralize their efforts; water carriers will often protect their team leader from the wind by surrounding them. When a leader has to get a repair or stop to answer nature, their domestiques will stay with them and pace them back up to the peloton. Called "water carriers" because they go back to the team car to pick up water bottles for team members. In Italian the term is "gregario".[72]
Weight weenie
A cyclist who is concerned about the weight of their bicycle or its components.[129]
Lifting the front wheel of the bicycle in the air through force transmitted through the pedals, and continuing to ride on only the back wheel. The rider maintains the wheelie by applying pedal strokes and rear brake in order to balance the bicycle on only the rear wheel.[22]
Wheelsucker, wheelsucking
A rider who sits on the rear wheel of others in a group or on another rider, enjoying the draft but not working. Also leech, leeching.[22][68]
Winter bike
A racing bicycle adapted for use in winter seasons. Typically these are less expensive and incorporate mudguards, which are rarely present on their modern summer counterparts.[130]
An outside lane on a roadway that is wide enough to be safely shared side by side by a bicycle and motor vehicle. The road may be marked with partial lane markings to designate the portion of the lane to be used by bicycles.[131]
Work
To work is to do "turns on the front", to aid a group of riders by sharing the workload of working against air resistance by "pulling on the front" of the group. Similar to pull. Often used in combination with other expressions: e.g. "He hasn't done any work all day, he has just sat on the breakaway." Working is used in many contexts in the peloton and road racing.[67]
