Highway bike groupsets defined: SRAM, Shimano and Campagnolo rankings
Mar
A street bike groupset is the gathering of elements that make you cease and go – in different phrases, the drivetrain, shifters and brakes.
Loads of firms make bike elements, however the market is dominated by three major manufacturers: Shimano, SRAM and Campagnolo.
Regardless of the variations between the manufacturers, the elements all do the identical job, even when there are some refined variations in how they strategy their particular duties.
We’ll begin this purchaser’s information by explaining the completely different groupsets obtainable of their hierarchies, then go into larger element on the person elements and the way they differ between manufacturers. We’ll end by explaining the advantages of the costlier groupsets and discussing compatibility.
If knobbly tyres are extra your factor, we’ve received a separate information to mountain bike groupsets. And whereas we’ve coated gravel briefly right here, we’ve additionally received a information to gravel bike groupsets for all the small print on gearing decisions.

What’s a groupset?
A groupset contains all of the mechanical elements to your bike – so principally all the things besides the body, fork, wheels, handlebar, seatpost and saddle.
You should purchase an entire groupset or the person elements and there’s some chance to combine and match between groupsets, though many objects usually are not inter-compatible.
Once you purchase a brand new bike, a motorbike model will typically sub in some cheaper elements with a groupset, so that you may for instance get a crankset that’s from a special stage or perhaps a completely different model from the remainder of the groupset.
The elements of a full groupset are:
- Crankset (additionally known as the chainset)
- Backside bracket (the bearings within the body on which the crankset spins)
- Brake levers/shift levers, normally mixed
- Rear derailleur
- Entrance derailleur
- Cassette (the gear sprockets on the rear of the bike)
- Chain
- Brakes
There’s an explainer of every part and extra groupset specifics later on this article.
Shimano groupsets: completely different ranges defined
Shimano is the oldest and most generally used of the three major manufacturers. It started life in Japan in 1921 when Shozaburo Shimano determined to begin making freewheels in a rented nook of a demolished celluloid manufacturing facility.
Quick-forward to at present, and it’s turn out to be so profitable that Shimano now accounts for at the least half of the worldwide bike elements trade.

Highway bike groupset elements
Now we all know how the completely different groupsets stack up, let’s have a look at the person elements to be present in a groupset.
We’ll clarify the important thing variations between the completely different manufacturers and what high-end options to look out for.
Highway bike crankset/chainset defined
Single, double and triple chainrings
The crankset (or chainset) is the most important a part of any groupset and contains the chainrings, the cranks and, normally today, the spindle that hyperlinks the 2 crank arms collectively.
Cranksets are grouped into three classes primarily based on the variety of chainrings used: double (the most typical on the street, also known as 2x or 1x/’one-by’); single (widespread in mountain biking and cyclocross/gravel, and also known as 1x or ‘one-by’); and triple (an older customary that’s hardly ever seen on new bikes).
Double crankset variations
- The customary double crankset is mostly utilized by professional riders and traditionally consists of a 53t massive ring and 39t small ring, or 53/39
- The semi-compact crankset – or pro-compact – is 52/36. This provides you a barely simpler climbing gear whereas nonetheless retaining an enormous high gear. It’s a widespread choice amongst aggressive novice riders
- The compact crankset is 50/34. It has turn out to be very fashionable due to its mixture of simple gearing and low weight
- Tremendous-compact or sub-compact cranksets supply a good decrease gear vary on double chainrings, equivalent to 48t/32, 48/31 or 46/30. These have gotten widespread with gravel riders and bikepackers who need the low, intently spaced gearing a 2x setup can supply.
- SRAM upset the applecart when it went 12-speed and launched cassettes with a 10t small cog, reasonably than 11 enamel. That lets it obtain comparable gear ratios with smaller chainrings, saving weight and providing even wider ranges. SRAM’s second-tier Drive eTap AXS groupset now features a low-range 43/30t choice, for instance.
Triple cranksets
- The triple is an older kind of chainset generally seen on classic street bikes and touring bikes. It provides a variety of gears, however at a weight penalty by including a 3rd chainring. It usually combines a 50t outer ring, a 39t center ring and an inside ring that has simply 30 enamel. It’s widespread with touring cyclists who worth a super-small ‘spinny’ ring when loaded down with panniers.
Single cranksets
- The single-ring crankset has just one chainring. To compensate for the lack of the smaller, inside ring, a 1× crankset is commonly matched to a wider-range cassette. Single ring cranksets use alternating vast and slim enamel with the next profile, to assist chain retention.
Highway bike shifters defined
For probably the most half, trendy street bikes use dual-action shifters that incorporate the gear levers into the brake levers.
Every model has its personal spin on the idea, so the way you shift mechanical gears on a Shimano-equipped bike is barely completely different to the way you shift on a Campagnolo- or SRAM-equipped bike.
Digital shifting nonetheless depends on paddles constructed into the brake levers however makes use of small servomotors within the derailleurs to make them transfer.
Digital drivetrains supply persistently exact shifting and decrease upkeep than a mechanically actuated drivetrain.
For a full rationalization of how the completely different methods change gear, learn our detailed article on the right way to change gear on a street bike.
Highway bike brakes defined
The issues don’t finish with the varied shift actions and whether or not they’re mechanically or electronically actuated. The number of brakes used on street bikes has additionally grown extra complicated in the previous couple of years.
Up to now, cable-operated, caliper rim brakes have been the one kind used on most street bikes, however latest years have seen street bike braking choices develop to soak up direct-mount rim calipers, hydraulic rim calipers (these stay exceptionally uncommon), cable-operated disc brakes and hydraulic disc brakes.
Hydraulic disc brakes are typically thought of to be the perfect all-round choice, however which kind of brake is finest for you relies on a variety of components. Understanding how street disc brakes work will make it easier to determine.
All three groupset manufacturers now supply hydraulic disc brake choices alongside rim brakes for almost all of their groupsets, they usually’re now dominant on new bikes.
Highway bike derailleurs defined
The derailleurs are the mechanisms – generally mech for brief – that transfer the chain from one gear to the subsequent.
The entrance derailleur does the job for the entrance chainrings, whereas the rear derailleur does it for the cassette; each are managed by the shifters.
Highway bike cassettes defined
The cassette is the cluster of sprockets mounted on the rear wheel. The extra sprockets on a cassette, the extra ‘speeds’ the groupset is alleged to have.
So, if there are 10 sprockets, you’ve a 10-speed groupset; 11 sprockets is an 11-speed groupset, and so forth.
(Word: ‘speeds’ solely refers back to the variety of sprockets, not the overall variety of gears obtainable; for that, you’d must issue within the variety of chainrings on the crankset.)
Having extra sprockets not solely offers you with a wider vary of gears but additionally means the jumps between them are usually smaller.
Smaller gaps imply it’s simpler to take care of an optimum pedalling cadence as you shift from one gear to the subsequent, and are subsequently most popular by racers.
For street bikes with a double crankset, 11-28t might be the most typical cassette vary, however Shimano, SRAM and Campagnolo all supply an enormous vary of decisions to fit your driving.
It’s additionally changing into extra frequent to see wider vary cassettes fitted as customary, with ratios equivalent to 11-32t and even 11-34t showing on some bikes, whereas SRAM provides a 10-36t 12-speed cassette in its eTap AXS Drive and Rival ranges.
Highway bike chains defined
The groupset model and variety of gears dictate the kind of bike chain you require (groupsets with a ‘larger’ variety of gears require narrower chains).
Dearer chains additionally typically have smoother, extra sturdy and extra corrosion-resistant coatings than their cheaper counterparts.
Moreover, some costlier chains have the pins and plates drilled to take away weight.
Word {that a} chain is a put on merchandise and needs to be changed at common intervals. There are instruments that can let you know when to exchange your bike’s chain.
Failure to do that will speed up put on in your cassette and chainrings, however you may prolong chain life by cleansing it often and solely utilizing the finest chain lubes to your bike.
Highway bike backside brackets defined
The underside bracket comprises the bearings on which the crankset spins and it suits into your body.
Backside brackets are available in many styles and sizes – we’ve received an entire information to backside bracket requirements – however so far as street groupsets are involved, all of them fall into considered one of two classes: press-fit or threaded.
Threaded backside brackets screw into your body on threads. Press-fit backside brackets, because the title suggests, are pressed into the body and held in place by friction.
Usually talking, press-fit backside brackets are much less handy than threaded ones with regards to upkeep and compatibility, however many producers favour them for purported weight and stiffness advantages, in addition to ease of producing.
What do I get with a costlier street groupset?
Does paying extra all the time convey you improved efficiency? Perhaps, however the larger up the vary you go, the smaller these efficiency advantages turn out to be, and the increments turn out to be much less noticeable, whereas the equipment will get much more costly.
Second-tier groupsets (Shimano Ultegra, Campagnolo Refrain, SRAM Drive) are typically nearly as good in useful phrases because the pro-level elements and significantly cheaper, however they weigh fractionally extra and have fewer unique shiny bits.
Weight
It was as soon as famously mentioned of bicycle elements: “Sturdy. Mild. Low cost. Choose two.” A lighter bike will all the time speed up and climb higher than a heavier one, however with out giving up energy, one thing needs to be compromised.
Whether or not you’re taking a look at groupsets, wheels and even full bikes, diminished weight is commonly the main contributor to elevated value.
With all of the street groupsets, the extra you spend, the lighter they get. The quantity of weight that you simply save to your cash diminishes dramatically on the higher finish, although.
These weight variations are the results of costlier supplies and refined, or extra time-consuming, manufacturing processes.
Along with additional machining, hole-drilling and excessive precision, costlier elements typically use supplies equivalent to carbon fibre, titanium, light-weight aluminium and ceramic bearings to attain the head in low weight and efficiency.
Sturdiness
When you’re spending more cash on a groupset, you’d count on it to outlast a less expensive choice. Sturdiness does enhance with value, however our expertise is that sturdiness additionally plateaus on the second-tier choices, and in some methods, really begins to say no at the costliest choice.
The costlier technical elements are constructed with larger precision, refinement and supplies that lend themselves to larger longevity. That is obvious in derailleurs and shifters the place the cheaper choices will develop play and slop over time, whereas the higher elements typically stay like new.
Put on objects, equivalent to cassettes and chainrings, nonetheless, are sometimes the reverse of this. Cheaper choices are made from heavier however extra sturdy steels, whereas the costlier variations are generally constructed from lighter however softer aluminium or titanium alloys.
Efficiency
Along with the advantages of diminished weight, costlier groupsets discover different methods of accelerating efficiency. Most noticeably, higher-priced choices present a smoother, extra exact and in some instances faster shift between gears.
This contains diminished effort on the lever, one thing that turns into obvious when you’ve been on the bike for a number of hours. It’s an space the place digital gears set the benchmark; final precision on the easy push of a button.
One other efficiency instance is elevated crankset stiffness to offer crisper shifting and extra environment friendly energy switch from the pedals to the rear wheel. That is achieved with extra complicated designs, and supplies that enhance energy and stiffness, however don’t add weight.
Braking raises a complete new checklist of advantages as costs go up. Merely put, costlier brakes are stronger, supply higher really feel and management, and cease you with much less hand pressure required.
This distinction is rather more obvious with rim brakes, although. There’s hardly any significant efficiency distinction between low- and high-end hydraulic disc brakes.
Further options
Moreover providing further gears, the costlier groupsets normally get new options first.
Shimano first launched Di2 digital shifting on the Dura-Ace stage, earlier than trickling it all the way down to Ultegra. The identical is true of extra mundane particulars – Dura-Ace was the primary to get attain adjustment utilizing a built-in screw reasonably than ugly shims, a function now discovered all the best way all the way down to Claris stage.
Equally, Shimano and Campagnolo now supply their higher-end cranksets in a common dimension that’s cross-compatible with compact, semi-compact or standard-sized chainrings. Because of this for those who ever want to change your chainring sizes, you are able to do so without having a brand new crankset.
Groupset compatibility points
It’s value being conscious that not all groupset elements from a given producer are suitable with each other, even in instances the place it looks as if they need to be.
Producers are inclined to replace their ranges incrementally over time so you may’t all the time assume, for instance, that one 11-speed part will work with one other in the event that they’re not from the identical 12 months or groupset.
There are variations within the exact quantity of cable pulled by completely different rim brake levers too, so you could not get optimum efficiency for those who transfer up the hierarchy whenever you change particular person elements.
That mentioned, groupsets of a given model are typically designed to work with one another, offering they share the identical variety of gears. (i.e. Shimano 11-speed with Shimano 11-speed, Campagnolo 11-speed with Campagnolo 11-speed.)
For particular compatibility queries, we’d counsel you ask your native retailer earlier than shopping for, seek the advice of producer technical paperwork on-line, or search recommendation on our discussion board. Shimano, for instance, maintains very detailed compatibility charts.
