Cycling Glossary

Last update: 2nd September 2006

This cycling glossary has some unusual definitions relevant to the Arun-Adur CTC. For a much more comprehensive glossary, see Sheldon Brown's Bicycle Glossary


Audax
Latin for 'daring'. A type of cycle ride designed to test the endurance of cyclists. Originated in France, events are run in this country by Audax UK.
Bidon
The French name for the drinking bottles that are inserted into bottle cages. You should always have two in hot weather!
Bonk
That horrible feeling when your body runs out of fuel on a long distance cycle ride. Eat and drink plenty as you go to avoid this.
Bostal
Local Sussex term for a pass ("col" in French) over the South Downs. Steyning Bostal is a good place to try out your granny gears.
Break wind
Not what you think! To cyclists, it refers to riding in front of another cyclist so that they can follow in the slip-stream.
Cadence
The rate or speed of pedal rotation whilst cycling. Cruising speeds are normally around 80-90 rpm while fast cycling requires around 100 rpm or higher. Anything below 70 and you are struggling!
Captain
The person on the front of a tandem who does some of the work plus the necessary bits like braking and steering as he is the only one who can see where they are going! (see Stoker).
Cassette
A group of sprockets and spacers that are assembled and secured by a separate locking ring onto a carrier which contains a freewheel assembly. The sprockets can be changed to suit your requirements and the complete assembly usually contains 7, 8, 9 or even 10 sprockets.
CTC
The Cyclists' Touring Club, Britain's largest national cyclists association. Join now!
Derailleur
French word that means what it says, i.e., "de-rails" the chain. It is used to describe the mechanism that physically forces the chain to move from one sprocket or chain-ring to the next. Most touring and racing bikes have a front- and a rear-derailleur.
Downs
Hilly regions in the South of England, i.e., North Downs and South Downs, which are separated by the Weald.
El Supremo(Dave Hudson)
An exceptional cyclist-friendly tea-stop, quite often found in the middle of nowhere. Mainly spotted on Audax events in the South East, but known famously throughout the country.
Etape
French word for "stage" as in a tour, e.g., Tour de France.
Fixed wheel
This refers to the rear gear or lack of them. The single rear sprocket is firmly fastened to the hub and does not freewheel! You must never stop pedalling on one of these bikes!
Freewheel
A set of sprockets that come in a ready-built assembly and contains the freewheel mechanism, which basically is a ratchet. The freewheel allows the gears to be stationary while the rear wheel rotates but will provide drive when the gears rotate faster than the rear wheel.
Granny gear
A very low ratio gear invented to make life easy for mountain bikers. Now also used by a lot of cycle tourists to avoid having to honk.
Grimpeur
French word meaning 'climber' and is used in the title of some hilly cycle rides e.g., Kit Hill Grimpeur starting from Tavistock.
Hand-sling
This is not the variety that you need after a fall but a helping hand from a colleague who pulls you from behind and launches you forwards. Used in team racing.
Hitting the wall
This is another expression for the 'bonk' or the point when you run out of energy. This can occur when trying to climb 'The Wall' south-east of Forest Row, East Sussex.
Honk
To stand on the pedals for extra power. Used when accelerating hard or when climbing a steep hill. Generally, touring cyclists never honk, they just select a lower gear, stay seated and spin the legs (this helps prevent knee strain). One advantage of honking is to give the backside a rest and allow the blood circulation to get to parts that may be going numb!
Kevlar
Modern man-made material that is woven into the casing of some bicycle tyres offering greater resistance to cuts and penetration. These tyres are usually referred to as "puncture-resistant" but this can vary wildly so find your own personal preference. My choice is Schwalbe Marathons for general touring including some rough stuff and Continental Gatorskins or GP4000 for quick road riding.
Lanterne Rouge
French for 'red light'. Unexcitingly, this is merely a name for the person who is last!
Mechanism
The English word(see derailleur) to describe the spring-loaded assembly that forces the chain to jump from one sprocket or chain-ring to the next when moving the gear lever(s).
The front 'mech' operates on the chain-rings and the rear 'mech' operates on the rear sprockets.
Musette
French for 'nose-bag' or a light shoulder bag containing energy bars and similar foodstuffs.
O.C.D.
L'Ordre des Cols Durs - Literally translated, it means "The Order of the Hard Passes". A club for people who like cycling in mountainous regions. It originated in France, but there is a UK club too. The vertical equivalent of Audax UK!
On the rivet
Derived from the days when everyone rode on the old saddles that had rivets holding a piece of leather onto a metal frame. 'Brooks' is the most notable manufacturer of such saddles ands they are still available today. 'On the rivet' meant that you were pedalling hard and literally sitting on the front rivet!
Pack
To give up on an event. Happens to the best of us and there is even an unofficial competition in Audax circles for the rider who packs the soonest!
Pedalling squares
When a rider becomes totally exhausted, usually climbing hills, and cannot maintain a smooth pedalling action.
Peleton
A large pack of riders and not a place for those of a nervous disposition!
Randonnée
Long distance cycling event designed for fit tourists. Organised by Audax UK.
Randonneur
Person who has succumbed to the addictive qualities of Randonnées.
Recumbent
A "laid-back" style of cycling and the first radical bicycle design since the "standard". A whole article could be produced on this style of bicycle but I will condense them down to the following short paragraphs.
Basically, a recumbent consists of two or three wheels and the rider sits in a hammock-style seat with legs extended forwards to the front-mounted pedals and chainrings. Steering is either by under-seat bars with linkage or by tiller- style bars to the front wheel(s).
On a two-wheeled recumbent, the rear wheel could be either a small(20inch) wheel or a conventional 700/26inch wheel but the rider sits higher in the latter.
There are two styles of three-wheeled recumbents. Either the rider sits low inbetween two conventional 700/26inch rear wheels or he sits higher in front of a single rear wheel and has two small(20inch) front wheels.
Getting on or off a two-wheeled recumbent, starting from a standstill and balancing requires a completely new technique but once mastered, they give greater comfort and faster rides although it is harder climbing hills on one.
The low riding position can be hazardous in traffic and riding two of these abreast is very unsocial and will receive lots of horn-blowing!
SPDs
Pedals that have an automatic spring-loaded locking mechanism to grip a metal plate fitted to the bottom of special cycling shoes. Insertion is automatic when you press down in the right place and removal is done by rotating the foot. SPD stands for 'Shimano Pedalling Dynamics' and they are sometimes referred to as "clipless" pedals
There are single-sided racing pedals, reversible single-sided with platform, double-sided and double-sided with platform pedals. However, I must point out that you will fall off during your first attempts to use these devices!
Stoker
The person who sits behind the captain on a tandem and does most of the work but sees very little!
Tandem
Alternative bicycle for two riders requiring large tubing, especially strong wheels and damn good brakes! Fitting S&S couplings to the frame helps when trying to transport one of these.
Tricycle(or Trike)
Alternative bicycle which normally has one front wheel and two rear wheels and a conventional riding position. The original trikes have standard sized wheels and could be seen a lot in the '60s but are quite rare nowadays. They require a good sense of balance especially when cornering! There are now Recumbent Trikes which are much easier to ride because of the low centre of gravity.
Valves
There are two types, Presta and Schraeder valves for bicycle tyres. The Presta valve is smaller and will cope with higher pressures than the larger car-style Schraeder valves, which are usually found on Mountain Bikes. Also, the Presta valve requires a smaller hole in the wheel rim which can be critical in maintaining strength in narrow road/racing rims.
You must specify the length of the valve body if you have deep aero-rimmed wheels.
Weald
Relatively flat areas of land in Sussex between the North and South Downs.
Wedgie
An upright bicycle with a narrow, hard seat called a saddle. Nothing like as comfortable as a recumbent.
Wheelsucking
The action of continuing to follow another cyclist without ever taking a turn in front. This will make you very unpopular! It is called "Tail- gating" when you follow a vehicle but this is a very dangerous practice and not to be recommended!
White(road)
A narrow road shown on an OS map without any colour and is marked as "Other road, drive or track". It can vary from a metalled surface to a gravel track!
