shimano sram sunrace campagnolo microshift

Bicycle groupsets comprise of all the gearing and braking components that make up the mechanical moving parts of a bike. This includes the chain, cassette, crankset, bottom bracket, derailleur/s, shifters, levers, and brakes, plus all the cables or any other smaller parts that make them work together.

Major cycling groupset brands include Shimano, SRAM, Campagnolo, and Sunrace. Each offers a wide variety of groupsets optimized for Road and Mountain bike cycling. When choosing a bike, it’s important to ensure that the groupset and gear ratio is correct for the style of cycling you intend to do.

These days, more and more bikes are using a 1x groupset, meaning there is only a single cog on the crank and no front derailleur or shifter. This reduces the weight and complexity of the system, making it easier to clean and maintain. However, for certain disciplines like cycle touring it is still necessary to use a 2x or 3x set up to get a wider range of gear.

How to Shift Gears on a Bike: Gear Shifting Explained for Beginners

Learning how to shift gears effectively will increase the enjoyment of your rides and help boost your ...

Traditionally, the number of gears is calculated by multiplying the front rings with the number of cogs on the rear cassette. So a 10-speed rear cassette in a 2x setup provides 20 gears. However, in 2x or 3x setups, several gear combinations will always overlap so in practice, you get less than indicated.

Down below we’ve listed all of the current groupsets by the best bicycle component brands out there. Although the majority of the market is shared by Shimano and SRAM, there is SunRace, who offers parts at more affordable rates, and Campagnolo, which is best known to make super high-end groupsets for road bikes. Anyway, take a look at the whole selection down below!

Shimano vs SRAM market share according to The Pros’ Closet’s data:

  • Road Bikes – 76% Shimano / 18.5% SRAM
  • Mountain Bikes – 27.7% Shimano / 71.5% SRAM
  • Cyclocross / Gravel Bikes – 51.1% Shimano / 46.9% SRAM

Shimano XTR

XC, Marathon, Trail, Enduro, All-Mountain

Ultimate race components

  • 12-speed
  • Greater flexibility & Action-optimized cockpit layout
  • HYPERGLIDE+ shifting – lets you pedal continuously while shifting

The XTR is Shimano’s top-of-the-range MTB groupset built for professional racing and enduro events. The bonded alloy and Chromoly steel crank are mounted directly which helps to reduce weight even further. It has all the other bells and whistles, including Dynamic Shape Engagement, Shadow Plus tech, and upgraded non-slip shifters. XTR is available with a 12-speed cassette in either 1x or 2x format.

Availability – evo.com

Shimano SLX

XC, Marathon, Trail, Enduro, All-Mountain

The SLX is a mid-range groupset with a 1x or 2x setups and a 12-speed cassette with the largest cog up to 51 teeth. The crank uses Hollowtech II technology to save weight and range from 165mm to 175mm in length.

The introduction of Dynamic Chain Engagement on the SLX helps reduce chain wear and provides smoother gearing over rough terrain. Furthermore, SLX is compatible with the i-SPEC EV standard which provides customizable mounting positions and brake lever integration.

Shimano Deore

XC, Marathon, Trail, Enduro, All-Mountain

Deore is the first in Shimano’s more professional groupsets, incorporating Hollowtech II technology. This includes a hollow bottom bracket that is connected to the crank for more efficient power transfer.

The M6000 model has a 10-speed steel cassette and uses Shadow RD+ technology with a controllable chain stabilizer. It’s available in both 2x or 3x configurations to provide 20 or 30 gears.

There is also a 12-speed Deore M6100 model that uses a 1x setup combined with a 30 or 32T crank and 10-51T cassette. The M6100 utilizes a modern Microspline freehub which is only compatible with certain wheelsets.

The higher-grade alloy Deore XT groupset is a lighter-weight option, with 1×12 or 2×12 setups. It is also compatible with Di2 electronic shifters.

Shimano Alivio

XC – Marathon

Alivio is very similar to Acera but uses lighter materials on certain parts to reduce weight. It also has a 9-speed cassette with double or triple crank and Shadow RD rear mech. However, with the addition of Shimano’s ‘Hyperglide’ technology on the Alivio, you get better accuracy and smoother gear changes. These groupsets are often found on the mid-level mountain and gravel bikes.

Shimano Acera

XC – Marathon

Acera is Shimano’s mid-range groupset, built to handle the rigors of rough mountain biking. It features a 9-speed rear cassette that can provide 18 or 27 gears, depending on whether you choose a 2x or 3x setup. The modern alloy cranks and steel chains look considerably better than lower groupsets.

Shimano Altus

XC – Marathon

Altus is a significant upgrade on Tourney, incorporating Shimano’s Shadow RD rear derailleur low-profile technology to avoid damage. However, it’s still a relatively low-quality set made of steel, with no clutch and a maximum 45 tooth rear cog.

It uses modern plastic thumb and finger shifters and can be paired with a double or triple crank. The side-swing front derailleur provides for better tire clearance than Tourney’s top swing.

Shimano Tourney

XC – Marathon

Tourney is the lowest quality MTB groupset that Shimano offers and is commonly found on the cheap mountain, touring, and hybrid bikes. The derailleurs are controlled with old-style thumb shifters which are often clunky and inconveniently placed.

Cassettes come in different sizes, from 6 to 8 cogs, and are usually paired with a Tourney triple crank to provide 18, 21, or 24 gears. Although cheap and heavy, Tourney drivetrains are tough and long-lasting.

Shimano Road Groupsets

Shimano Dura-Ace

Shimano Dura-Ace FC-R9100 11-Speed Crankset

Dura-Ace is the best groupset available in Shimano’s road bike range, comprising a combination of alloy, carbon, and titanium parts. It’s super lightweight and the groupset of choice by many professional cycling teams, including Dimension Data and Team Ineos.

Dura-Ace includes rim, mechanical or hydraulic disc brakes and is available as standard or with Di2 electronic shifting.

Shimano Ultegra

Ultegra is the second-best groupset available from Shimano and is commonly found on top quality carbon road bikes. Its components are built from highly durable and lightweight materials, designed for heavy use over long distances.

It has an 11-speed cassette and is available in the standard version or with electronic Di2 shifters. The groupset is available with high-quality rim brakes, mechanical discs, or hydraulic disc brakes.

Shimano 105

The 105 is one of Shimano’s most popular professional groupsets, often found on mid-range road bikes. It includes an 11-speed cassette that works well with either a single or double crank. The 105 groupsets have also been upgraded to include hydraulic disc brakes. It’s a high quality, durable groupset that can be used in competitive racing events.

Shimano Tiagra

Tiagra is Shimano’s most affordable quality groupset and offers a slightly downgraded version of the more professional 105 groupsets. It has a 10-speed cassette that can be combined with a single or double crank for 10 or 20 gears. In 2019, Shimano upgraded the Tiagra groupset to include hydraulic disc brakes rather than rims.

Shimano Sora

Sora is a slight upgrade on Claris, offering a 9-speed cassette with a double or triple crank to provide 18 or 27 gears. It also comes with rim brakes and combined levers to control the entire system.

Shimano Claris

Shimano’s most affordable groupset is Claris, commonly found on entry-level road bikes. It includes simple rim brakes with rubber and alloy levers, which control both the gears and brakes. The 8-speed rear cassette can be combined with either a double or triple crank, to provide 16 or 24 gears.

It’s suitable for recreational riders doing short commutes or weekend rides but the components are not durable enough for long-distance or heavy touring.

Shimano Gravel Groupsets

Salsa – Cutthroat GRX 810 – MSRP $4,199


Shimano GRX

Shimano GRX derailleur

Shimano’s newest range of groupsets is aimed at the emerging gravel bike market. They are made up of components from other Shimano groupsets, combined to provide the ideal conditions for gravel riding. This also covers a range of other cycling disciplines, including bike touring, cyclocross, and other styles of adventure biking.

ProRX800 (Ultegra equivalent)
MidRX600 (105 equivalent)
EntryRX400 (Tiagra equivalent)

All Shimano GRX groupsets use hydraulic disc brakes with inline levers, Shadow RD derailleurs with chain stabilization, and either 1x or 2x setups. The lowest range GRX R400 groupset is made up of Tiagra parts, the RX600 uses mostly 105 parts, and the highest level RX800 uses Ultegra components.


Mountain / Gravel

SRAM Brand logo

Like Shimano, SRAM makes both road and MTB style groupsets in varying price ranges. The American company was founded in 1987 in Chicago, Illinois, making it one of the youngest groupset manufacturers.

The SRAM name is an acronym of the founders, Scott, Ray, and Sam. In 2015, SRAM released the first wireless groupset, the SRAM Red eTap. Over the years, SRAM has acquired several other component manufacturers, including RockShox for suspension and Avid for disc brakes.

These days, SRAM is far more focused on the MTB market, leaving Shimano to largely dominate the road bike market. They offer three different disc brake options: Level, G2, to Code, which increase in quality and are matched with similar-quality groupsets.

Apex 1 Rear Derailleur

Apex is SRAMs entry-level groupset with rim brakes and an 11-32T cassette. It uses SRAMs WiFli system which allows a wider range of gears without needing a triple crank. This helps to keep weight down. There is both a 10-speed and 11-speed cassette available with either a 1x or 2x setup. On SRAMs Apex 1 groupset you can get a rear derailleur to accommodate up to 42T cogs.



Founded in 1933 in Italy, Campagnolo is arguably the oldest producer of bicycle gears and is often credited with inventing the rear derailleur. Despite being formed earlier, Shimano only started manufacturing cycling gear components later on.

For almost two decades after World War II, Campagnolo’s parallelogram shifting technology led the world of professional cycling. Nowadays, Campagnolo is less prominent than Shimano and SRAM but remains the groupset of choice by many professional cycling teams. The company no longer produces groupsets for the MTB market.

One thought on “Groupset Overview – Shimano, SRAM, Campagnolo, SunRace, microSHIFT

  1. Ray says:

    I buy older low budget brand name bikes such as Specialized, Trek, Giant, Iron Horse, and others. It’s a good way for me to get decent, albeit older bikes and I enjoy working on them. I have traditionally stuck with Shimano basically because of price and availability and because I have owned many bikes and most of them have had Shimano parts on them so it’s a brand that I trust based on experience. However lately while shopping I have been seeing a lot of buzz surrounding SRAM and Microshift.I don’t have a lot of disposable funds to throw at my hobbies and I have several of them so I’m always looking for the best deal. That’s my bottom line but the keyword in that is “deal” and not “price” because my goal is to find a balance between price and quality. With Shimano, I often use Altus although I prefer Acera and Alivio. I am however interested in possibly trying out SRAM and Microshift components but I don’t always need or have the money for a complete groupset in a single project. I’m doing research at this point and although I have seen a lot of articles which say that both companies offer “Shimano compatible” components, I am looking for some actual feedback from cyclists who have experience in mixing and matching brands and components regarding function, reliability, longevity, etc. If anyone has specific comments or advice regarding this I can be reached at [email protected] and thank you in advance for any and all insight into this subject.
