, 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.
Ideally, a feed zone should be along a long, uncongested straight section of road, with a wide shoulder for team personnel and vehicles. A slight uphill is desirable, as it will slow the passing riders and make grabbing the musettes easier; the grade should not be so steep as to cause the riders to struggle. The roadway approaching the feed zone should be straight with a long unobstructed sightline, so riders may easily identify the personnel from their teams and position themselves for a smooth pickup.

G

gap: A distance between two or more riders large enough for drafting to no longer be effective. Also used as 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. A gap can also refer to the space in between a jump and the landing, which is common in mountain biking.

G.C.: Abbr.: general classification. the timing splits used to determine who is winning in a stage race. calculated from the first rider over the line each day time is then measured back by gaps from the winner of the day. Time gaps are then calculated back between riders and added to the overall position of riders relative to each other. Riders can attack in stage races for time rather than winning the days 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 days stage despite not contesting the finish as the overall gap the breakaway gains helps them "on G.C."

hammer: Hammer is used in three different ways in road cycling.
  1. as a phrase describing what happens to a rider who suddenly loses the ability to race, as in "The man with the hammer got him" or "He got hit by the man with hammer". This is a reference to the experience boxers have when their legs become powerless and weak just before collapsing (as if they have been hit with a hammer) following a severe blow to the head. The abruptness with which this happens differentiates it from hitting the wall. Alternative expressions are "'tapped'" short for "he got tapped by the man with hammer".
  2. "to put the hammer down" means to pedal hard, often with the purpose of trying to eliminate opponents in a road race. As in the phrase "We really put the hammer down and sprinted to the end". Some commentators have been known to reference a wide range of workshop tools in their ongoing search for sporting metaphor.
  3. more literally, the verb "to hammer" refers to pounding along powerfully on the pedals, e.g. "Leipheimer really hammered hard for the entirety of stage 19".


handicap: A style of road racing in Australia where riders are given time handicaps in bunches, with scratch being the last riders to leave and limit being the first riders to leave. The time intervals between groups, and the allocation of riders to groups is decided by the race handicapper, based on rider's ability, age and form. Race honours are usually awarded to the first 5 to 10 riders (depending on the size race) and to the fastest time.

 behind, hoping to create space between the sprinter and the pack. When the leadout man is exhausted he will move to the side to allow his teammate to race in the sprint. Often a line of leadout men will be used to form a leadout 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 leadout is for the sprinter to achieve high speed at the sprint approach using as little of his own energy as possible, so he has as much energy as possible for the final sprint.

let go: Two meanings, one the opposite meaning of the other
  1. To let go a rider or break is allowing a rider(s) to attack and not responding even if one has the capability to follow the attacking move. This is done for tactical reasons. Can be applied in the plural: "the peloton let the break go".
  2. To let go the wheels is to not be able to "hold a wheel" unable to follow the pace. "he let the wheels go" or "let go the wheel" the difference is the use of wheel rather than the rider or riders. if you let a rider or a break go you do so voluntarily. To let go a wheel is involuntary but has slightly derogatory edge in that the rider "let the wheels go" before he was pushed to his absolute limit, to be "dropped" (subtle).


limit: First riders to depart in a handicap race.

The madison is a team event in track cycling, named after the first Madison Square Garden in New York, and known as the "American race" in French and in Italian and Spanish as Americana.-History:...

: The madison is 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 his partner by a hand sling. The name comes from the original Madison Square Garden

omnium: An omnium is a multi-stage event that differs from a stage race in that points are assigned for placing in each stage rather than a time. Therefore a rider may win with a slower time than another rider, but more points. Conceivably a rider can win the omnium without finishing each event.

on the rivet: Describes 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.

on your wheel: Phrase describing the condition of being very close to the rear wheel of the rider ahead of you. Used to inform the rider that you have positioned yourself in their slipstream for optimum drafting. For example: "I'm on your wheel".

open road race: Generally going from point A to point B; can include multi-laps. Can also mean a club event in which non-club members can enter.

overlap: Riding in a position such that the leading edge of one's front wheel is ahead of the trailing edge of the rear wheel of the bicycle immediately ahead. Overlap is potentially dangerous because of the instability that results if the wheels rub, and the simple fact that it allows the trailing rider to turn only in one direction (away from the wheel of the rider ahead). In road bicycle racing, overlap can be a significant cause of crashes, so beginning riders are instructed to "protect your front wheel" (avoid overlap) whenever riding in a pack.

P

paceline: Group of riders riding at high speed by drafting one another. Riders will take turns at the front to break the wind, then rotate to the back of the line to rest in the draft.

, 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. All primes won shall be awarded to riders even if they withdraw from the race. 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. When primes are announced for a given group, only riders in that group or behind it at the beginning of the prime lap are eligible. Prizes can be cash, merchandise, or points, depending on the race.

prologue: A short individual time trial before a stage race, used to determine which rider wears the leader's jersey on the first stage.

SAG station: A location along the course of a long mass-participation recreational ride providing mechanical and/or medical assistance to riders in need. Volunteers at the SAG station may also dispatch SAG wagons to assist riders stranded along the course. A SAG station may also function as a food stop. "SAG" (most commonly written in all uppercase in the United States but without capitals elsewhere) comes from a 1930s British expression about riders "sagging" off the back of a group. It was adopted in the 1940s when road-racing restarted in Great Britain to mean a following vehicle into which riders sagged when the effort became too much and they dropped out of a race. SAG is sometimes described as an acronym for 'support and gear', 'gear' referring to: mechanical support.

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.

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. 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. The winner is the person with the most points at the end of the race.

Tubular tyres
Tubular tyres

: Tubular tyres are cycle tyres that 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 (up to 10 bar or 145 psi, or higher for racing and track-specific tires) which reduces their rolling resistance. They typically result in wheelsets that are lower in overall weight than comparable clincher wheels, because of the shape of the rim, the tire construction, and the lack of rim strips. Tubulars can 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. However, they are difficult to replace and repair and are generally more expensive than clinchers. Also called sew-ups, tubies, or tub.

turbo-trainer: A trainer that spins a fan assembly at the same time (for pedal resistance and air flow).

turn: A turn is a rider sharing the workload on a pace line "he took a turn" or "he is doing a lot of turns on the front". Missing turns can be expressed thus "he has missed a few turns now and has stopped working". In a breakaway the riders expect to share the work equally in "turns". A rider who doesn't take his turn is "sitting on the break".
