It suits riders aged around seven-11, who may find its triple chainset baffling.

The bottom bracket on a bicycle connects the crankset (chainset) to the bicycle and allows the crankset to rotate freely.

Back in January I did not know my derailleurs from my drop bars, my cranks from my chainset, my brackets from my bearings.

The 2006 winner Nicolas Vouilloz rode a 150 mm travel bike with a Dura Ace chainset and semi slick rear tyre.

He rode on 8oz tubulars He had handlebar controls for his gears, Mafac Racer brakes, Campagnolo hubs and a Stronglight chainset.

The system is useful for folding bicycles (where a multiple front chainset could foul the bike's folding mechanism) and in recumbent bicycles and freight bicycles (where small wheels and/or increased weight require a wider range of gears with smaller steps).

The bike was equipped with 15-speed Suntour ARX GT gears, originally designed for use on road bikes, and the Stumpjumper also featured Mafac cantilever brakes and a TA Cyclotourist chainset, both designed for touring bikes.

In 1990 the Japanese bike component manufacturer SunTour introduced the Browning Electronic AccuShift Transmission (SunTour BEAST) - a triple chainset system for mountain bikes in which one quarter of the circle is hinged along a radius.

The crankset (in the US) or chainset (in the UK), is the component of a bicycle drivetrain that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel.

This device, however, is attached to the frame rather than to the crankset.

It may also be referred to as the "tread" of the crankset.

The most common tandem crankset is a set of four cranks.

The motor was designed within the hub of the crankset axle.

The 2009 model included the option of a front triple crankset, giving 27 speeds.

Current systems have a 2-speed hub gear incorporated in the crankset or bottom bracket.

There are other instances where adapters can be used to fit a crankset made for one standard into another.

The crankset is a steel, cottered mass market unit manufactured by Williams.

At least one manufacturer offers a crankset in which the crank arms may rotate independently.

These systems do not have sensors on the crankset or cassette to determine what gear the bicycle is in.

Most flat bar bikes are fitted with a triple crankset giving 24 or 27 speeds.

The rear crankset typically has many chainrings, sometimes on both sides.

The crankset that drives a bicycle via the pedals.

The special crankset must also be paired with a rear hub that can be driven from the left side.

This is known as a three-piece crankset.

The front crankset typically has only one chainring.

It has no pedals, no crankset and chain, and no training wheels.

The distance from the handlebars to the crankset is likewise longer than a conventional bike and can give problems for cadence sensors.

A planetary-gear crankset offers two different gear ratios with just one chainring.

If you have a track hub, it's better to operate on the bottom bracket or - for minor shifts - on the crankset.

The larger spindle in addition to the larger bottom bracket shell make for increased stiffness of both the frame and crankset.

Power meters using strain gauges are mounted in the bottom bracket, rear freehub, or crankset.

Modern crankset chainrings can be swapped out, as can cogsets.

The middle chainring, in the case of a triple crankset, usually has the most shaping to aid in shifting up and down.

The simplest conversion uses the existing freewheel/cassette and crankset, the chain being cut to fit the desired gear ratio.
