Shimano 105 Groupset History List

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, fork, stem, wheels, tires, and rider contact points, such as the saddle and handlebars.

These parts typically include the following:

Road Bike Groupsets Mountain Bike Groupsets Other Shimano Groupsets. Japanese company Shimano certainly know a thing or two when it comes to bicycle components. Founded in 1921, Shimano has spent almost 100 years meticulously innovating, developing and perfecting design methods in order to produce some of the most renowned and respected products available on the cycling mar.
New Shimano 105 series is introduced with Shimano Linear Response (SLR) brake system which is to give the cyclist more control over the caliper brakes. 1987 SHIMANO 600 Ultegra series are in the market.

2 brake levers or
2 integrated brake levers/shifters
2 brakes, front and rear
2 derailleurs, front and rear
1 bottom bracket
1 crankset
1 chain
1 cogset, freewheel or cassette

With the following forming part of some groupsets:

RX-100 - Reported to be the same as the 105 group except for finish. RSX - A lower-priced but well-constructed group with drop-bar brake/shift lever: 7-speed rear indexing, and front indexing for triple chainwheels. The front shifter also works with Sachs 3 x 7 internal-gear hubs.

1 headset (more commonly included with vintage groupsets)
1 seatpost
2 hubs, front and rear (although, most manufacturers now offer groupset-branded pre-built wheels)
Pair of pedals
assorted cables and cable housing^[1]^[2]

Except for special commemorative versions, manufacturers do not actually package the various components 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.^{[citation needed]}

The major groupset manufacturers are Campagnolo for road bicycles 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 while Claris, Veloce and Apex are their entry level road racing group sets, respectively.

List of Groupsets[edit]

Below is a list of the three largest manufacturer's groupsets for Road and MTB applications. Each manufacturer's offering is arranged in descending price/quality. The number of sprockets of the cassette in each groupset is shown in brackets. 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, although some of them overlap. Please see the article on bicycle gearing for more information.

SRAM are phasing out 3 ring front chainrings in their MTB range for a 2 front chainring and single chainring, 10 or 11 sprocket rear cassette setup, commonly found on road bikes.

Specialist[edit]

There are some groupsets which are designed for a specific purpose (track cycling, downhill etc.). Some are just partial groupsets which are intended to be used with other groupsets.

Shimano Dura-Ace Di2 7970 - (10) - electronic shifters and derailleurs intended to be used with regular Dura-Ace 7900 parts (cranks, cassette, chain, bottom bracket etc.)
Shimano Dura-Ace (track) - (1) - Track bikes
Campagnolo Pista - (1) - Track bikes
Campagnolo Time Trial - (N/A) - Time Trial components with bar-end controls, chainrings with oversized toothing and super-light brake levers in composite material.
Shimano Hone - (9) - Based on the Deore LX M580 groupset for Enduro and Freeride applications, discontinued in favor of Zee and SLX
Shimano Zee (10) - Freeride and Downhill - A lower-end version of Saint
Shimano Saint - (10) - Downhill and heavy-duty applications
Shimano Capreo - (9) - including a cassette incorporating a 9-tooth sprocket for small-wheeled bicycles

The Shimano Nexus began as an internal hub only and has slowly grown into its own groupset including a higher end internal hub (Alfine, previously Nexus 'Redline'), chain, shifters, cranks, brakes and calipers.

Shimano Alfine - (8/11) - Internal (planetary) hub gearing, hydraulic disc brakes or mechanical calipers
Shimano Nexus - (8) - Internal (planetary) hub gearing, drum brakes or calipers
