anatomy of a road bike explained diagram Some terms in the cycling world can be challenging to understand. 

We have made a list of some common technical words and explained them here as simply and accurately as we can.


Jargon buster guide


    • Alloy: An alloy is a mixture of two or more elements, at least one part is metal.


    • Bearings: Ball bearings work as a way of letting something spin/rotate freely and smoothly.
    • Bottom Bracket: The bottom bracket is housed in the bottom bracket shell of a bike.
    • Bottom bracket shell: The bottom bracket shell is where the bottom bracket is fitted, it is where the seat-stay, down tube and seat-tube join.
    • Brake levers: Brake levers are the handles/levers mounted on the handlebars used for stopping or slowing the bike.
    • Brake Cable: The brake cable system is made of two parts, the inner cable and the outer cable.


    • Carbon fibre: This is a composite that has a very high strength-weight ratio and is ideal for bicycle frames and components.
    • Cantilever brakes: Cantilever brakes are designed to operate in symmetry to touch the rim walls at the same time.
    • Cassette: The cassette is the cluster of sprockets fixed onto the splined freehub on the rear wheel.
    • Chain: The chain transmits the power from the chainring to the rear wheel of the bike.
    • Chain stays: The chainstays exit the bottom bracket shell in a rearwards direction where they meet the rear dropouts.
    • Chromoly: A type of steel that contains chromium and molybdenum. Another name you may see for chromoly is 4130 steel.
    • CX: CX is a short description for cyclo-cross.


    • Disc brakes: Disc Brakes comprise of a metal disc attached to the hub of the wheel, and can be operated either by hydraulic fluid or by cable.
    • Down tube: The down tube connects the bottom of the head tube to the bottom bracket shell.
    • Drop handlebar: Drop handlebars are predominantly used on road and track bikes.


    • Entry level: The term entry level is often used for first time riders wanting to buy their first bike.


    • Fork: The forks connect to the stem/handlebars allowing you to turn the front wheel and balance the bike.
    • Frame: The cycle frame is the main piece of the bike composed of the frame tubes. The wheels and other components are attached to the frame.
    • Freehub: The freehub is a component of the rear hub. It has a ratchet mechanism built into it to allow freewheeling/coasting.
    • Front derailleur: The front derailleur is used to move the chain in a sideways motion to allow shifting between chainrings.


    • Gear cables: The gear cable travels from the gear lever to the corresponding derailleur to allow the changing of gear.
    • Gear levers: Gear levers, often called shifters, enable the changing of the derailleur/gear mechanisms.


    • Handlebars: Bicycle handlebars are a one piece component fixed to the stem of a bike. The handlebars primary concern is to steer the bike.
    • Headset (Aheadset): The headset is a multi-piece component that is mounted at the head-tube of the bike.
    • Head tube: The head tube houses the headset and the steerer tube.
    • Hubs (front and rear): The hubs on a bike are the centre part of the wheels.


  • MTB: MTB is the abbreviation for Mountain Bike.


  • Rear derailleaur: This moves the chain from one rear sprocket to another, whilst keeping the chain tensioned.
  • Rear shock: This is a mechanical component that’s purpose is to absorb and smooth out the impact at the rear wheel of a bicycle, usually found on mountain bikes.
  • Rims: The rims are the perfect circular hoops that the tires are mounted onto.


  • Saddle:The bike saddle is the most intimate contact point on a bicycle. It’s clamped to the seat-post by the saddle rails.
  • Seat-post: The seat-post is a removable extension that is placed in the seat-tube of the frame.
  • Seat stays: Seat stays connect the top of the seat tube to the rear dropouts.
  • Seat tube: The seat tube is the insertion point for the seat-post.
  • Steel: Steel is an alloy. It’s manufactured by combining iron and other elements.
  • Suspension fork: This is a type of bicycle fork that has a suspension or shock absorbing unit.
  • Spokes: Spokes connect the hub to the rim.
  • Sprocket: A sprocket is another name for one of the individual cogs on a cassette or freewheel.
  • Steerer tube: The steerer tube is the upper part of the bicycle forks.
  • Stem: The stem is the linking component to join the handlebars to the steerer tube of the forks.


  • Tapered (head tube): These head tubes feature a bigger diameter at the bottom than the top.
  • Thumb shifters: Thumb shifters are very simple gear levers that were very common on MTB’s.
  • Tires: Bike tires fit on the outer circumference of the rims.
  • Top tube: The top tube is the joining tube from the seat tube to the top of the head tube.
