Short answer: Shimano's road tiers run Claris, Sora, Tiagra, 105, Ultegra and Dura-Ace, and SRAM's run Apex, Rival, Force and Red. The step you actually feel is the move up to Shimano 105, or SRAM Rival: that is where 12 speeds, hydraulic disc brakes and the better lever design all arrive together. Above that, you pay mostly for lower weight and electronic shifting rather than a better ride. Below it, each tier adds one more gear and a little refinement.

What a groupset tier actually changes
A groupset is the set of components that make the bike go and stop: the shift and brake levers, the front and rear derailleurs, the chainset, cassette, chain and brakes. Manufacturers sell them in tiers, and the tier on a bike is one of the main things that sets its price.
As you move up the tiers, four things change:
- Number of gears, which decides how close together the gears are and how wide the overall range is.
- Brakes, from rim or cable-operated disc at the bottom to hydraulic disc from the middle tiers up.
- Weight and materials, with more carbon and lighter alloys at the top.
- Shifting, from mechanical cables to electronic systems at the upper tiers.
What does not change much is reliability. A well-adjusted lower tier shifts perfectly well. The higher tiers are lighter, crisper and more refined rather than dramatically more dependable.
Shimano road tiers
| Tier | Current series | Speeds | Shifting | Typical brakes |
|---|---|---|---|---|
| Claris | R2000 | 8 | Mechanical | Rim or cable disc |
| Sora | R3000 | 9 | Mechanical | Rim or cable disc |
| Tiagra | 4700, and R4000 from 2026 | 10, and 11 on R4000 | Mechanical | Rim, cable or hydraulic disc |
| 105 | R7100 | 12 | Mechanical or Di2 | Hydraulic disc |
| Ultegra | R8100 | 12 | Di2 electronic | Hydraulic disc |
| Dura-Ace | R9200 | 12 | Di2 electronic | Hydraulic disc |
Two recent changes are worth knowing.
Tiagra was updated in 2026. The new Tiagra R4000 moves to 11 speeds with hydraulic brakes, takes its lever shape from 105, and allows an 11-36T cassette, where the old Tiagra 4700 topped out at a 34T sprocket. That narrows the gap to 105 considerably.
CUES is replacing the bottom of the range. Shimano's CUES family is gradually taking over from Claris, Sora and Tiagra, though those older groups will stay available for a few years. You will already find CUES on some entry road bikes: the Merida Scultura Rim 100 uses a CUES 2x9 drivetrain. CUES is a separate system with its own rules, covered in our CUES compatibility reference.
At the top, Ultegra and Dura-Ace are now electronic only in their 12-speed versions. 105 is the highest tier still offered with mechanical 12-speed shifting.
SRAM road tiers
| Tier | Current shifting | Speeds | Notes |
|---|---|---|---|
| Apex | Mechanical and AXS electronic | 11 or 12 | Entry level, used mostly on single-chainring gravel builds |
| Rival | AXS wireless electronic | 12 | The mid tier, updated in 2025 |
| Force | AXS wireless electronic | 12 | Race tier, updated in 2025 |
| Red | AXS wireless electronic | 12 | SRAM's flagship |
SRAM went electronic earlier and more completely than Shimano. Its current Rival, Force and Red are all 12-speed wireless systems, called AXS, and SRAM's mechanical road groups are older 11-speed designs that have not been updated for some time.
SRAM also offers most tiers in single-chainring versions, and wide-range XPLR versions aimed at gravel riding.
Shimano and SRAM equivalents
The two brands do not line up exactly, but these pairings are close enough to compare bikes:
| Shimano | Roughly equivalent SRAM |
|---|---|
| 105 Di2 | Rival AXS |
| Ultegra Di2 | Force AXS |
| Dura-Ace Di2 | Red AXS |
Below 105 the comparison breaks down, because SRAM's entry offering, Apex, is aimed mainly at single-chainring gravel bikes rather than at budget two-chainring road bikes. On entry-level road bikes in India you will almost always see Shimano.
The jump you actually feel
If you are choosing between bikes, this is the part that matters.
Each step below 105 adds one gear and some refinement. Claris to Sora to Tiagra is a gradual climb. Each is a bit smoother and adds a cog, but the riding experience changes in small increments.
The move to 105 is different, because several things change at once. You get 12 closely spaced gears, so you are rarely between a gear that is too easy and one that is too hard. You get hydraulic disc brakes as standard, which is a larger improvement in control than any gear change. And you get Shimano's better lever shape, which is noticeably more comfortable on the hoods for a long ride. That combination is why riders who move from a Sora bike to a 105 bike describe it as a different kind of bike, not a slightly better one.
Above 105, the returns shrink. Ultegra and Dura-Ace are lighter and shift with a more refined feel, and both are electronic. None of that makes you meaningfully faster or more comfortable on an ordinary ride. The money is usually better spent on wheels, a bike fit or tyres.
The new 11-speed Tiagra R4000 changes this picture a little, since it brings hydraulic brakes and 105-style levers down a tier. On a bike that has it, the gap to 105 is much smaller than it used to be.
One caution on the other side: a bike marketed as "105" is not always a full 105 groupset. Some builds use 105 shifters and derailleurs with a different brand of chainset, cassette or brakes to hit a price. That is a legitimate way to build a good-value bike, but compare like with like when you are shopping.
Mixing tiers and brands
| Combination | Works? | Note |
|---|---|---|
| Shimano 12-speed cassette, chain and chainset across 105, Ultegra and Dura-Ace | Yes | Same 12-speed road standard |
| Shimano Di2 parts across 105, Ultegra and Dura-Ace | Yes | Same electronic system |
| Mechanical shifters with Di2 derailleurs | No | Different systems |
| 11-speed and 12-speed parts together | No | Different spacing and chain width |
| Shimano shifters with SRAM derailleurs, or the reverse | No | Different cable pull and systems |
| Road Shimano with CUES | No | CUES uses its own LinkGlide system |
Two freehub points catch people out when changing cassettes or wheels. Shimano's 12-speed road cassettes fit a standard 11-speed road freehub. SRAM's 12-speed road cassettes, which start with a 10-tooth cog, need SRAM's XDR driver instead. Our freehub and cassette reference and chain compatibility reference cover the details, and our GRX reference covers Shimano's gravel groups.
Which bikes use which tier
Examples from the range, to show what each tier costs on a complete bike:
| Tier | Example bike | Price |
|---|---|---|
| Shimano Claris, 8-speed | Cannondale CAAD Optimo 4 | ₹85,599 |
| Shimano CUES, 2x9 | Merida Scultura Rim 100 | ₹86,990 |
| Shimano 105 11-speed shifting, mixed build | Pardus Super AL 105 11S | ₹89,990 |
| Shimano 105, 12-speed mechanical | Pardus Super AL 105 12S | ₹1,29,990 |
| Shimano 105, 12-speed mechanical | Basso Venta R 105 | From ₹2,09,990 |
| Shimano 105 Di2 | Gusto Duro Evo Di2 | ₹2,49,990 |
| Shimano 105 Di2 | Pardus Spark Sport 105 Di2 | ₹2,69,990 |
| Shimano Ultegra Di2 | Look 795 Blade R38D Ultegra Di2 | ₹6,99,000 |
| SRAM Rival AXS | Look 795 Blade R38D Rival | ₹7,71,000 |
| Shimano Dura-Ace Di2 | Pinarello Dogma F | ₹17,60,000 |
Note how tight the gap is at the bottom: an 8-speed Claris bike and an 11-speed 105-shifting bike sit within about ₹5,000 of each other. Higher up the table, prices climb steeply, though much of that comes from the frame and the brand rather than from the groupset alone.
Prices are indicative and move with exchange rates and import duty. Standards outlive stock, so a bike listed here may be out of stock at any given moment.
Frequently asked questions
Is 11-speed Shimano 105 (R7000) still a good buy?
Yes: 11-speed 105 R7000 shifts well, is durable, and replacement parts remain widely available, so a bike built around it is a sound purchase. The trade-off is that it is the previous generation, so 12-speed parts will not work with it later. Check whether a bike described as 105 has the full groupset or only 105 shifters and derailleurs, because a mixed build can still be excellent value, but it is not the same thing as a complete 105 bike.
Can I upgrade a Sora or Tiagra bike to 105 later?
Rarely economically: moving from 9 or 10-speed to 12-speed 105 means replacing the shifters, both derailleurs, cassette and chain, and often the chainset, and older road wheels built for 8, 9 or 10 speeds usually have a shorter freehub that will not take an 11 or 12-speed cassette. If the bike has rim or cable brakes, you cannot get 105's hydraulic brakes without new levers and calipers too. Added together, the upgrade often costs close to the difference in price between the two bikes, which is why buying the right tier at the start usually works out better.
What is the difference between Shimano Di2 and SRAM AXS?
Both are electronic shifting systems, but they are built differently: SRAM AXS is fully wireless, with a small battery on each derailleur and in each shifter, while Shimano's current 12-speed Di2 uses wireless shift levers with the derailleurs wired to a single main battery. In use, both shift precisely and need charging rather than cable adjustment. The practical differences are in charging routine, the feel of the levers, and the fact that the two systems cannot be mixed.
Which groupset tier suits Indian roads best?
For most riders, Shimano 105: it is the lowest tier with hydraulic disc brakes as standard, which matter more for control in traffic and in the monsoon than any difference in gears, and its parts are robust and easy to replace. Higher tiers use lighter components that can wear faster, which is not an advantage on dusty, gritty roads. If your budget sits below 105, prioritise a bike with hydraulic or at least good disc brakes over one extra gear.
How long does a groupset last?
The shifters, derailleurs and brakes last many years with basic care, but the chain, cassette and chainrings wear with use and need replacing periodically. Replacing the chain before it stretches too far makes the cassette and chainrings last much longer, so checking chain wear regularly is the single cheapest way to extend a groupset's life. Our guide to telling when your chain is worn explains how.
Identifying what your bike has
The tier name is usually printed on the rear derailleur and on the chainset. If only a code is printed, such as RD-R7100 or RD-R3000, the number tells you the series. Bring the code, or a photo of the rear derailleur, and we can tell you exactly what you have and what it works with.
Ask TBA Guide with your budget and the kind of riding you do, and we will point you to the tier, and the bikes, that make sense.
