After months of anticipation, the following era of SRAM Crimson AXS has made its debut, bringing with it a recent aesthetic and enhanced efficiency throughout the board, promising improved braking and entrance derailleur shifting capabilities.
Having had the chance to check trip the SRAM Crimson AXS forward of its official launch, I feel now could be the right time for an in depth comparability between SRAM and its longstanding competitor, Shimano.
Be aware that that is my opinion of driving each groupsets, slightly than an in-depth dive into their technical specs. For all of the nitty-gritty particulars, try our full launch story and overview.
Weight
The newest iteration of SRAM Crimson AXS proudly claims the title of the lightest highway disc brake groupset ever produced by the corporate, shedding a formidable 154 grams in comparison with its predecessor. This weight discount is primarily attributed to a complete redesign of the brake and shifter parts, leading to a notable 90-gram lower in system weight. Moreover, developments reminiscent of a carbon fiber decrease cage and revamped jockey wheels contribute to additional weight financial savings throughout the groupset.

Traditionally, Shimano’s Dura-Ace Di2 held the title for the lightest disc brake highway bike groupset on its launch in 2021. Nonetheless, SRAM Crimson AXS now surpasses it by practically 100 grams.
Shifting efficiency
The efficacy of drugs shifting stands as a pivotal facet of any groupset, and SRAM has made strides in addressing previous criticisms with the redesign of its entrance derailleur. Actually, I can say that enhancements have been made to reduce shift distances and improve velocity and reliability, although some customers could discover the distinction in shift really feel to be marginal in comparison with earlier fashions. In distinction, Shimano’s Dura-Ace Di2 has at all times had impeccable shifting efficiency, characterised by seamless transitions each up and down the cassette, even below load.

Regardless of SRAM’s efforts to refine its shifting mechanism, I feel Shimano maintains its edge on this regard, because of its superior Hyperglide know-how and persistently dependable efficiency.
Each groupsets provide spectacular shifting high quality, however for the racer that requires the quickest attainable responsive instances, I am unable to suggest something however Shimano – one all!
Braking efficiency
Recognizing the necessity for enhanced braking efficiency, SRAM has made vital efforts to raise the braking high quality of its new Crimson groupset. The redesign of the brake levers, which now combine the grasp cylinder into the shifter physique, ends in a a lot lighter brake really feel, and drastically improved modulation. Moreover, repositioned pistons on the calipers contribute to enhanced braking efficiency, marking a major enchancment over earlier iterations.
Whereas Shimano’s braking programs have lengthy been synonymous with reliability, SRAM’s newest developments have positioned it as a formidable contender.

I’ve been capable of one finger brake in any place, whether or not its on the hoods, or within the drops. However that stated, Shimano is not any slouch within the brake division both. They really feel dependable as ever, and use mineral oil as an alternative of DOT fluid, which is advantageous for dwelling mechanics.
However SRAM has, for my part, overtaken Shimano right here, and by fairly some margin. Modulation, lever weight, and stopping energy are all up on Shimano, so SRAM takes one other level.
Ergonomics
One thing that Shimano has at all times executed so extremely properly through the years is groupset ergonomics. I’ve at all times been received over by its shifter design, and that’s no totally different for the R9200 Dura-Ace groupset. The shifter our bodies are the right diameter to be simple to grip, whereas not feeling uncomfortably small, and the marginally inboard slanted hoods permit for an aggressive race place whereas tucked up on the hoods.
SRAM alternatively, have at all times been barely polarizing. The outdated SRAM levers had been, properly, attention-grabbing and personally one thing I by no means acquired together with. So, after I noticed the brand new group for the primary time I used to be over the moon to see that they’d been fully redesigned – however have they mounted them?
When driving on the hoods, they’re brilliantly comfy. The repositioned grasp cylinder makes for a well-sized handhold that provides loads of management. The brake levers are actually flared barely too, which caters properly for more and more widespread flared handlebars.

Within the drops, the levers really feel nice, and SRAM additionally provides round 10mm of adjustment to maneuver the lever nearer to the handlebar, one thing that folks with smaller palms will definitely profit from.
Button tactility is fairly related throughout the board – each Shimano and SRAM have assured feeling shifts which can be laborious to overlook, and each programs are so good at this level that selecting between the 2 is solely private choice.
The place SRAM is let down barely is driving in an aggressive place on the hoods. The form of the entrance of the lever makes it laborious to know the hoods comfortably whereas in a breakaway place – sure this received’t have an effect on all people, however that is SRAM’s top-level groupset, so it is price taking into consideration.
In fact, it’s so shut between the 2 manufacturers that I’ve to present every one half a degree right here. Adjustability, button high quality, and hand positions are all very related, and whereas Shimano may edge SRAM for breakaway driving, in the identical vein, if you’re a gravel rider, SRAM may be the higher possibility.
Aesthetics
Aesthetic preferences differ, however for me, Shimano’s modern, understated design has an actual sense of timeless magnificence. Conversely, SRAM Crimson AXS stands out with its daring styling, that includes aggressive strains and modern shifters that add a contact of aptitude to any bike.

Do not get me mistaken, they each look nice, however for what its price, on appears to be like alone, I might nonetheless select Dura-Ace.
Options
Relating to wi-fi shifting, SRAM has led the way in which from day one. As the primary to go wi-fi, it did a formidable job of defending the mental property of its designs and made it nearly unattainable for different manufacturers to comply with go well with.
Maybe essentially the most helpful characteristic of the SRAM Crimson groupset is the detachable and interchangeable batteries. Bikes are massive, invariably, get fairly soiled too – so with regards to charging your groupset, you don’t essentially wish to be traipsing your bike by means of your lounge to cosy it as much as a plug socket.
SRAM negates this by having detachable batteries that cost by way of a USB hub. It additionally signifies that when you run out of battery mid-ride, you may swap your one nonetheless working battery to have the ability to change gear on least on one in every of your mechs.

SRAM has additionally leveled with Shimano within the button division too, including new further ‘bonus buttons’ on the within of the lever hoods. Equally to Shimano’s auxiliary buttons on the highest of the hoods, these could be programmed to vary screens on Hammerhead head items, change gear, and extra.
Whereas each Shimano and SRAM characteristic app integration for the respective merchandise, SRAM’s software program is a bit more person pleasant. This, together with every part else means one other victory for the American model.
Energy meter
As soon as upon a time, an influence meter would have been a uncommon commodity within the biking world, however with over a decade of advancing tech, energy meters are just about the norm now with regards to top-level bikes.
Each Shimano and SRAM have their very own energy meters on top-level groupsets, nonetheless the know-how concerned is barely totally different.
SRAM’s system is a chainring-mounted unit that makes use of a single pressure gauge to get an influence output correct to +/- 1.5%. Though mounting this on the chainring could be very correct, it does imply that the left and proper energy steadiness must be estimated slightly than really measured.
Shimano’s energy meters, alternatively, are crank-based. This implies they must measure items on each the left and proper crank arm, that means they will calculate a real energy steadiness, and measure energy as soon as once more to +-1.5%.
It’s fairly shut between the 2 of them, nonetheless I have to say that I’ve had a extra dependable expertise through the years with Sram, so although it’s tight – I’m giving the purpose to them.
Value
Relating to worth, it is honest to say that each SRAM and Shimano are each fairly darn costly. After I tallied up the totals for the 2 manufacturers I used to be reminded simply how a lot a top-of-the-range really groupset prices – however they’re comparable.
For a full groupset, together with rotors, chargers, batteries, and powermeters – every part, you’re looking at a complete of £4248 for SRAM, and £4281.87 for Shimano.
But it surely’s price saying that not many individuals really purchase a groupset by itself, and with each groupsets so shut in worth, bikes are prone to retail for a similar value that means to nearly each shopper, this one is a draw.
Conclusion
All in all I feel the competition has grow to be nearer than ever between the 2 manufacturers. I’m somebody who has swapped between the 2 groupset producers over the previous couple of years, and I actually suppose as a brand new buyer I might wrestle to choose one over the opposite – nonetheless, there are some key factors I might make.
Shimano on the one hand, I feel is extra ergonomic for race bike positioning and as such makes it my choose for the highway, however with regards to gravel, I don’t suppose the hoods present as a lot safety as SRAM. Add to that the plethora of gearing choices obtainable for one-by and two by setups, and I feel which groupset I might select would actually rely upon my driving type.
For extra longer miles, and steeper climbs, I feel SRAM is tough to cross up, however as a racer at coronary heart, the shift velocity of Shimano offers them the win – simply…
