BikeParts Wiki

A groupset or gruppo (from the Italian for "group", often misspelled grouppo) is a bicycle component manufacturer's organized collection of mechanical parts. It generally refers to all of the components that make up a bicycle excluding the bicycle frame, forks, stem, wheels, tires, and rider contact points, such as the saddle and handlebars.

These parts typically include some of the following:

Except for special commemorative versions, manufacturers do not actually package the various different component together to be sold by retailers as a complete groupset. Therefore when a modern road groupset is bought after-market (as an upgrade for an older bike, or for someone building their own bike), the customer can choose which parts they require, the price of the groupset is just the individual prices of the chosen parts added together.

The major groupset manufacturers are Campagnolo for road bicycle and Shimano and SRAM for both road and mountain bikes.

Manufacturers typically offer a range of several groupsets, each targeted at a different budget or use. For instance, Dura-Ace, Super Record and Red are the top-of-the-line road racing groupsets for Shimano, Campagnolo and SRAM respectively.

List of Groupsets for 2009[]

Below is a list of three current manufacturer's groupsets for Road and MTB applications, each manufacturer's offering is arranged in descending quality. The number of sprockets of the cassette in each groupset is shown in brackets. This is often referred to as "10-speed" or "9-speed" meaning the number of sprockets, but the total number of gears is determined by this number multiplied by the number of chainrings, for example a bike that has a double chainring and a 10-speed cassette has 20 gears. However in practice the number of usable gear ratios is usually fewer as several of the gears may be the same ratio or may not be reachable due to the crossover of the chain.
