Darimo always manages to wow with sleek carbon components and almost impossible light weights, and their new Sigma carbon cranks are no different. Sub-280g for a set of carbon arms and carbon spindle, with an alloy driveside bearing race and direct-mount chainring interface, and you can set it up for road, gravel, or even mountain bike action.
Also, if you have any bike with an aero seatpost that’s itching to go on a diet, Darimo might just be able to help – now with 34 different non-round shapes for their ultralight carbon T1 posts. Plus, they keep adding literally hundreds more integrated cockpit options – with various flare, length, width & finish options, as well as a new elliptical steerer option specifically for Pinarello’s latest integrated road bikes.
And of course, we always love to see a new Dangerholm custom build…
Darimo Sigma ultralight carbon crankset made in Spain

Darimo’s latest ultralight carbon creation is their new Sigma crankset.
It looks sleek and simple and cool and all, but not so extraordinary right?
Well, not until Darimo explains how light & stiff it is, or that you can use it from road to gravel to mountain bikes, too.

Darimo claims a weight of 280g for the carbon arms and carbon spindle – with aluminum pedal inserts, driveside bearing race, and direct mount chainring interface. (These 165mm arms and axle weigh just 279g.) That’s pretty light for a road crank, but incredibly light for an off-road-rated crankset.
For carbon crank comparison, a set of 172.5 SRAM Red cranks weigh 310g with their alloy Dub axle, Force about 410g, and XX SL at 380g.

Darimo explains that their boxy oversized arms and carbon spindle construction make the cranks not only super light, but super stiff and tough, too.
They also plan to offer the new Darimo Sigma cranks in road, gravel, and mountain bike axle widths to get your perfect chainline. And also they’ll have any crank arm length you could need, within reason. Darimo suggested that will probably mean starting at 155mm arms, and going up to 180mm for example. Ultimately, lengths will simply depend on demand since Darimo machines their own aluminum molds and can react to consumer demand.

Pricing is not officially set in stone yet, but will be approximately 1100-1200€. Also for now, they are assuming they’ll stick with the SRAM 8-bolt direct mount interface as that is ideal for 1x & 2x chainring and even power meter spider compatibility. But Darimo is still waiting to be sure that SRAM won’t object to their using this common standard.
Darimo promised more details soon, possibly as early as this week.
Next Darimo + Dangerholm collabo on this “TECHNICALLY A GRAVEL BIKE”

Dangerholm has worked with Darimo for several years. They are both dedicated to building insanely light, but still capable bikes and components, so it always seemed like a good match-up.
The latest project from Gustav Gullholm aka Dangerholm is this Scott Scale RC SL Gravel bike. Yes, it is a hardtail mountain bike with a 100mm fork. But in Gustav’s own words written on the chainstay, once he put the flared 1-piece carbon Darimo Nexum Gravel handle bar on it it became, “technically a gravel bike.“
The smart suspension fork and dropbar are an interesting update, as two years ago Dangerholm reassured us that a rigid cross-country hardtail mountain bike is already essentially a gravel bike.

Of course, the new Darimo Sigma cranks feature at the heart of the new gravel bike build. But while they are the newest component to grace the new project bike, it’s not quite the most flashy…


Everybody does 1-piece carbon cockpits these days, but Darimo has played with 1-piece carbon seat assemblies too.
We already spotted that wild prototype Darimo seatpost with a fixed ultralight saddle bonded to the top last summer at Eurobike, where Dangerholm had it on a more conventional weight-weenie 5.86kg XC build of the same bike, which he was showing off together with Trickstuff. But with the dropbar setup, SRAM Red Xplr, and a RockShox SID SL Ultimate Flight Attendant fork… maybe Dangerholm is thinking a 6kg build makes more sense for gravel than mountain biking?
Darimo ultralight aero seatposts for more bikes!

One of Darimo’s most popular products is their ultralight non-round aero seatpost. With so many bikes fitted with uniquely oval, elliptical, and D-shaped aerodynamic seatposts, you are often stuck with whatever proprietary post came stock with your bike. But often, these stock posts are not exactly light, even when you buy a $/£/€ 10,000+ road or gravel bike.
So Darmio to the rescue – now with 34 non-round shapes to choose from!


Offered with either their conventional T1 titanium bolts & alloy hardware for offset heads or the even lighter T1 Loop that swaps in a dyneema rope loop for zero-offset heads, there’s quite a bit of weight to save. Darimo says their aero posts typically save around 70-90g off stock options.
And now there are ultralight aero & non-round posts to fit an ever-expanding list of bikes, including those from: Berria, BMC, Cannondale, Canyon, Colnago, Enve, Factor, Giant, Pinarello, Sarto, Scott, Specialized, Trek & X-Lab. And they keep adding more, based on data they get about the latest bikes being sold with proprietary seatpost shapes.
Speaking of Sarto…

Darimo had one of the just-released custom Sarto Raso Gravel Wide carbon bikes on hand in Girona to show off one of their latest ultralight aero seatpost shapes.


It seems like a good match here too, combining the handmade custom-geo & layup Italian carbon gravel frame with Darimo’s handmade custom Spanish carbon components that not only come in a wide range of sizes but also can tune the layup to rider weight or riding style needs.
Darimo Nexum integrated cockpits add new elliptical Pinarello option

There are apparently thousands of possibilities for those Nexum handlebar cockpits, even before you factor in rider customization. And Darimo keeps adding more. Their latest is an elliptical steerer tube interface.
Why would you need that you ask?
Well, I guess you haven’t just bought a new Pinarello Dogma or F-series to later realize that its proprietary steerer tube shape has you locked into the stock handlebar.

So, Darimo added a new Pinarello-compatible elliptical steerer to their long list of customizable Nexum cockpit options.
- 50-130mm stem lengths in 10mm steps
- 36-44cm widths in 2 cm steps
- 0°, 6°, or 16° flared drops
- fully integrated routing or internal only in the bar
- round or Pinarelllo elliptical steerer interface
- UD, forged carbon, or classic 3K weave top layer finishes
- gloss or matte finish, with white, black, or white & red logos
Darimo Carbon still does custom aluminum, too

Darimo Carbon may be the company name, but they still do a lot of custom Spanish CNC-machined alloy, as well.
I’m asucker for a rainbow of anodized aluminum colors. But get past the flashy looks, and these customizable (length, angle & stiffness) IX2 AL stems are a great way to add a truly fit to your bike’s existing cockpit. Especially if slamming that stem hasn’t already worked for you.
You can order all of this by reaching out to Darimo directly through their barebones website, or find a local Darimo boutique bikeshop to help you in tricking out your bike.
