Terms

Terms people actually search for first.

Attack Attack

A sudden acceleration meant to open a gap on a group or the peloton. Success depends on reading terrain, rivals' fatigue and remaining distance together: attacking too early burns out before the summit, too late fails to gain time. Climbers typically pick the final climb, classics specialists a cobbled sector or short steep ramp, and just after a corner is a classic launch point.

Bike Fitting Bike Fitting

Adjusting saddle height and setback, handlebar height, stem length and cleat angle to a rider's body and flexibility. In the US and UK a basic session runs $100-300, more with video analysis and pressure mapping. Most beginner knee, back and neck pain traces back to poor setup, so it's worth doing before spending on equipment upgrades.

Bonk Bonk

A sudden crash in energy and focus when glycogen stores in the muscles and liver run out, also called "hitting the wall". Once hunger is felt it's already too late, so the only real prevention is eating 60+ grams of carbohydrate per hour at steady intervals starting 30-45 minutes into a ride. Modern pros take in up to 120 grams an hour.

Breakaway Breakaway

A small group that escapes the main peloton and tries to stay clear to the finish. Breakaways form for stage wins, sponsor exposure and mountain or sprint points, and their fate depends on cooperation within the group and how hard the chasing teams commit. The peloton stretches and compresses the gap like elastic, calculating the catch for the final kilometres, so few breaks survive to the line.

Cadence Cadence

Pedal revolutions per minute, abbreviated rpm. A low cadence in a heavy gear loads the muscles and knees; a high cadence shifts the load toward the cardiovascular system instead. Most riders hold 85-95 rpm on flat ground and somewhat less on climbs. For a beginner, the fastest fix for knee pain is simply shifting to an easier gear and spinning faster.

Cassette Cassette

The stack of sprockets on the rear wheel hub, usually 11 or 12 speeds, labelled by its smallest and largest tooth count, such as 11-28T or 11-34T. A larger largest sprocket means an easier gear for climbing. Riders in hilly areas are often advised to run a wider-range cassette such as 11-32T or beyond, and derailleur capacity should be checked before swapping.

Century Century

A 100-mile (160 km) ride in a single day, the classic distance benchmark for amateur road cyclists in English-speaking countries. Organised century rides usually offer supported routes with rest stops, and completing one is a common first major goal after learning to handle a bike and build a base of fitness.

Cleat Cleat

The part bolted to the sole of a cycling shoe that locks into a clipless pedal. It improves power transfer and stabilises the pedal stroke, but before the twist-and-release motion becomes automatic, riders often fall over while stopped, a rite of passage sometimes called a "clipless crash". Start with the release tension at its lightest and practise in an empty car park.

Domestique Domestique

French for "servant", a rider who races to support the team leader rather than to win personally. Duties include carrying bottles and food from the team car, shielding the leader from the wind, chasing down rivals' attacks, and pacing a leader back to the group after a mechanical or puncture. A rider with leader-level ability who takes on this role is called a super-domestique.

Drafting Drafting

Tucking in directly behind another rider to sit inside the pocket of still air they create, cutting the wind resistance you have to overcome. It can reduce the power needed to hold race speed by roughly 20-40%, with the saving growing deeper inside a large group. Almost every road-racing tactic starts from this one piece of physics; it's banned in individual time trials, which enforce a minimum following distance instead.

Echelon Echelon

A diagonal formation riders form across the road in a crosswind, since drafting directly behind someone stops working when the wind comes from the side. Road width limits how many riders it can hold, and anyone forced out is left exposed in the wind, in what's called "the gutter", quickly losing contact. Strong teams deliberately accelerate in exposed crosswind sections to split the field and isolate poorly positioned rivals.

FTP (Functional Threshold Power) FTP (Functional Threshold Power)

The highest average power, in watts, a rider can sustain for about an hour, the baseline figure for structured training plans. It's usually estimated at about 95% of a 20-minute maximal test average, and training zones from recovery to anaerobic are set as percentages of it. A beginner might sit at 150-200 watts, a well-trained amateur 250-300 watts, and dividing by body weight shows real climbing ability.

General Classification General Classification

The overall ranking in a stage race, calculated by adding up each rider's finishing time on every stage, commonly abbreviated GC. The rider with the lowest total wears the leader's jersey and, if it holds to the finish, wins the race. Flat stages usually finish in one big group with identical times, so real gaps in GC mostly open on mountain stages, time trials and finish-line time bonuses.

Gran Fondo Gran Fondo

Italian for "big ride", an organised long-distance event open to any rider who pays the entry fee, unlike a closed professional race. Courses typically run 40-125 miles with checkpoint cutoff times, and while times and placings are recorded, simply finishing is the goal for most entrants. Spring and autumn are the busiest seasons for gran fondos across the US and UK.

Grand Tour Grand Tour

The top tier of three-week stage races, the Tour de France, Giro d'Italia and Vuelta a Espana, covering around 21 stages and 2,000+ miles. Each runs 23 days including two rest days, and the rider with the lowest combined finishing time across every stage wins overall. Winning two or more Grand Tours in a single season is treated as an extremely rare feat.

Green Jersey Green Jersey

Worn by the leader of the Tour de France's points classification. Points are awarded by finishing order on each stage and at intermediate sprints, with flat-stage wins worth up to 50 points, effectively making it a sprinters' prize. Because a rider still has to survive mountain stages within the time cut and finish consistently near the front, it's occasionally won by an all-rounder rather than a pure sprinter.

Gruppetto Gruppetto

The back-of-the-race group formed by sprinters and domestiques who struggle on mountain stages, also called the "autobus". Its goal isn't placing but simply beating the time cut, a percentage of the stage winner's time, so riders inside it share pace-setting duties and ride at the minimum effort needed to survive. It's a survival strategy aimed at being fresh enough to compete again on the next flat stage.

Hors Categorie Hors Categorie

French for "beyond category", the top tier of climb, judged too difficult to fit within the standard 4th-to-1st category scale. Classification weighs length, average gradient and position within the stage; Alpe d'Huez, Mont Ventoux and the Tourmalet are classic examples. These climbs carry the most King of the Mountains points and are where the general classification is most often actually decided.

Indoor Trainer Indoor Trainer

General term for equipment that holds a bike stationary for indoor riding. A resistance unit clamps the rear wheel to apply load; a roller trainer has the rider balance freely on three drums. Most riders today use a "smart" direct-drive trainer, which replaces the rear wheel entirely and syncs with virtual riding apps, treated as close to essential gear in regions with long stretches of unrideable outdoor weather.

Intermediate Sprint Intermediate Sprint

A designated sprint point partway through a stage, awarding points-classification points, and in some races a small time bonus, by finishing order. Because breakaway riders and sprinters' teams chasing the green jersey often clash here, the peloton's speed can spike suddenly even with 60+ miles still to race.

King of the Mountains King of the Mountains

The classification decided by adding up points won for cresting rated climbs first. Climbs are graded from 4th category up to 1st, with Hors Categorie above that, and higher categories carry more points. In the Tour de France its leader wears the white jersey with red polka dots, and it's often chased through a breakaway by a rider who has given up on the general classification.

Lanterne Rouge Lanterne Rouge

The rider who finishes a Grand Tour in last place overall, French for the red lantern once hung on the back of a train. Despite being last, it carries its own mark of honour for surviving all three weeks, and stories exist of riders deliberately angling for the position to attract press and crowd attention. It isn't an official classification, so no jersey or prize money comes with it.

Lead-out Lead-out

A tactic in which a sprinter's teammates ride in a single-file line to lift the pace above 40 mph and deliver their sprinter to the final metres of a flat finish. Each rider pulls at the front until spent, then peels off, with the final lead-out rider releasing the sprinter around 150-200 metres from the line. One rider out of position or a wheel touch can collapse the entire train.

Monument Monument

Collective term for cycling's five oldest and most prestigious one-day classics: Milan-San Remo, the Tour of Flanders, Paris-Roubaix, Liege-Bastogne-Liege and Il Lombardia, each covering roughly 150-180 miles in a single day. A single win can define a career, and only three riders in history have won all five.

Musette Musette

A small shoulder-strap cloth bag handed to riders at a feed zone, holding gels, energy bars, sandwiches and bottles. Riders hook an arm through it while still moving, transfer the contents to their jersey pockets, and drop the empty bag in a designated zone or toss it to roadside fans. Team-branded musettes are popular collectibles among fans.

One-day Classic One-day Classic

A traditional race decided in a single day with no cumulative time, typically 120-190 miles and built around distinctive obstacles like cobblestones, short steep climbs or harsh weather, demanding a different kind of rider than stage racing does. The five most prestigious are the Monuments, and because most fall in spring, the period is often called "the classics season".

Out of the Saddle (Dancing) Out of the Saddle (Dancing)

Riding position with the hips lifted off the saddle, rocking the bike side to side under body weight to generate more force. It produces greater power on steep climbs and sudden accelerations but raises heart rate quickly and is hard to sustain. The key technique is keeping the bike from sliding backward as you rise out of the saddle.

Pave Pave

French for the rough cobblestone roads still found in stretches of northern France and Belgium. They define Paris-Roubaix and the Tour of Flanders, and individual sectors are rated up to five stars for difficulty. The vibration punishes hands and lower backs and causes frequent flats and crashes, so riders prepare with wider tyres, lower pressure and thicker bar tape.

Peloton Peloton

French for "little ball" or platoon, the term for the main group in a race. Riding tightly bunched maximises the drafting benefit and reduces individual effort, so the group constantly stretches and compresses like a living organism. Positioning battles intensify before climbs, corners and crosswind sections, and most crashes happen at exactly those moments.

Polka Dot Jersey Polka Dot Jersey

Worn by the leader of the Tour de France's King of the Mountains classification, white with red dots. Introduced in 1975, the pattern is said to be drawn from the packaging of the era's sponsor, a chocolate brand. Points accumulate by cresting rated climbs first, and it's a jersey often pursued through repeated breakaway attempts by a rider out of general-classification contention.

Power Meter Power Meter

A device fitted to the crank, pedal or hub that measures actual pedalling output in watts. Unlike heart rate, it isn't affected by weather or daily condition, making it the standard reference for training load and race pacing. Single-sided entry units in the US and UK run $400-600, dual-sided units $1,000 and up, and it's not essential gear for a first season.

Rainbow Jersey Rainbow Jersey

Worn for a full year by the reigning world champion, white with five coloured stripes, until the next world championship. It can only be worn in the discipline it was won in, and even after the reign ends the rider keeps the right to wear the stripes on cuffs and collar for life. The jersey carries enough symbolic weight that a so-called "curse of the rainbow jersey", a poor season right after winning it, has become a running storyline.

Skinsuit Skinsuit

A one-piece, skin-tight racing garment designed to remove the flapping drag of a regular jersey. It's essentially mandatory in time trials and track racing and has become common in road sprint finishes too. Fabric with fine surface texturing manages airflow, and a well-fitted suit is credited with saving tens of seconds over a 25-mile time trial.

Stage Race Stage Race

A multi-day race format in which a stage is ridden each day and finishing times are added together to decide an overall winner. It ranges from three-week Grand Tours to week-long races like Paris-Nice and single-day-plus events. The dual structure, each day is its own independent race and simultaneously one piece of the overall classification, is the root of the sport's tactical complexity.

Sticky Bottle Sticky Bottle

An illegal tactic in which a rider takes a bottle handoff from the team car and holds on deliberately, letting the car's acceleration tow them forward. Taking a bottle is legal; being towed by one is not, and it draws a fine and a time penalty, watched for by officials following the convoy of cars. Riders returning to the pack after a mechanical or a nature break are especially tempted by it.

Through and Off Through and Off

A rotating pace line in which riders take turns at the front breaking the wind before peeling off and rejoining at the back. It's the core technique for holding speed in a breakaway or team time trial; if one rider pulls too long, the whole group slows. Beginners are safest keeping pulls short and peeling off into the wind side without braking hard.

Time Cut Time Cut

The cutoff time, set as a percentage of the stage winner's time based on course difficulty and average speed, beyond which a finisher is disqualified in principle. It's exactly why sprinters group together into a gruppetto on mountain stages. If enough riders would miss it and disqualifying them all would gut the field, race officials sometimes pardon the group with a points penalty instead.

Time Trial Time Trial

An event where riders start individually at set intervals and race the clock alone, with no drafting allowed, often called "the race of truth". Aerodynamic bikes, skinsuits and teardrop helmets are standard, and position and pacing decide the result. Outside the mountains, it's where Grand Tours open their biggest time gaps, and it frequently settles the overall winner.

Watts per Kilogram Watts per Kilogram

Power output divided by body weight, the best single predictor of climbing ability. Absolute power matters most on flat ground, but on a gradient a rider has to move their own weight against gravity, so this ratio decides the order. Based on a 20-minute effort, a beginner sits around 2-3 W/kg, a strong amateur 3.5-4.5 W/kg, and elite Grand Tour climbers are estimated to hold about 6.5 W/kg on long climbs.

Yellow Jersey Yellow Jersey

Worn by the overall leader of the Tour de France, introduced in 1919 so spectators could pick out the leader at a glance. The colour is generally said to match the yellow newsprint of L'Auto, the paper that founded the race. The Giro d'Italia uses a pink maglia rosa and the Vuelta a Espana a red jersey for the same purpose, with a new leader's jersey awarded on the podium after each stage.
