For years, gravel cycling tech has been surging ahead of road-specific innovations. Visiting Sea Otter Girona last week presented a host of new and interesting tech changes, though one or two of these could be a long way off achieving approval from the masses.

32″ will be 2027’s hottest tech

It is with the contentious tech that we’ll start. A small selection of brands, including Megamo and Avona were showcasing gravel bikes with 32-inch wheels. 

Avona had the most success with their rider, Leon Kaiser, winning the men’s UCI race. You can check out his setup here, but what struck me was how good the frames are looking in medium sizes.

I also caught a glimpse of Avona’s design in the small size and while I didn’t manage to grab a photo (sorry), the geometry looked well balanced. I will be very interested to see how brands can deliver 32-inch wheels for smaller riders.

The Megamo’s frame looked like a mostly finished product, though the Vittoria tyres were marked up as prototypes. These, however, are a set of the brand’s T50 tyres and I doubt it’ll be long until their launch.

The reason that the 32-inch wheel size is significant lies in its lack of compatibility with existing frames and tyres. For mass adoption of the larger wheels to take place, riders would need to buy a new frame, the wheels, and pick from an initially small selection of tyres.

While I fully expect to see a rush of pro athletes experiment with the 32-inch standard, I believe that recreational riders will need strong evidence that larger wheels will genuinely benefit their riding – not just racing at pro speeds. Given the cost involved in switching, the bike industry’s usual line of “trust me, it’s faster,” just won’t cut it.

Darimo’s full carbon cranks are truly bonkers

If you’re ever at a bike show and Darimo are in attendance, you’re in for a treat. The Spanish lightweight specialists are always coming up with something fun and I was very keen to get my hands on their finished Sigma carbon cranks.

The left crank arm and spindle are now one piece. It’s a lovely piece of carbon engineering, but the fun didn’t stop there.

Darimo has a prototype carbon chainring for the Sigma cranks that they’re still working on. The brand told me that work is currently going into the material used for the chainring teeth. 

Darimo’s founder, Damia, was kind enough to share plenty of details with me and says that they’ll have axle lengths for road, gravel, MTB and MTB wide, while crank lengths will range from 150mm to 172.5mm.

Obviously, Darimo had a set of weighing scales on hand. A pair of cranks weigh 251g, while the 46T chainring is just 86g.

Whaleroad’s 14-speed road groupset

Stopping by at Cykl bike’s stand, I got pointed towards a very interesting groupset from Chinese brand Whaleroad on the Montpellier brand’s gorgeous titanium frames. 

The 1×14 R7 road groupset pairs, in this instance, an 11-46T cassette with a solid chainring.

But aside from the tightly-spaced cassette, and wireless rear derailleur, I was most interested in the removable battery which can by charged via USB-C.

While I wasn’t able to ride the bike to which the groupset was fitted (it was a large), I did have a play with the shifter buttons. The click here was very nicely damped, yet still encouragingly positive.

Conti goes wider on value clincher road tyres

I love riding top-end tubeless tyres, but their cost means that 2nd-tier clincher tyres are my choice for higher wear duties, such as commuting.

Continental has a new 32mm width for the Grand Prix tyre. Launched a few days ago, this was the first time I’d got my hands on them and under the warm Girona sunshine, the tyre felt impressively supple.

Other golden tech nuggets

Specialized Off-Road Racing’s Geerike Schreurs had a very interesting addition to her S-Works Crux. The brand’s MTB XC side-loading box is generally found on the Epic and looks to provide some of the storage that other brands incorporate into the frame. (Image Credit: Liam Cahill)

And it was effective. Gee quickly popped the box open, revealing dedicated slots for gravel racing essentials. ‘Aero’ was also mentioned, so it’ll be interesting to see if Specialized makes this an official Crux product in the future. (Image Credit: Liam Cahill)

Pedal choices are always interesting for gravel and while for ages, the options were either MTB or road, now you’ll find some riders, like Ridley’s Daan Soete, opting for single-sided MTB pedals. (Image Credit: Farrelly Atkinson)

I was keen to see Ceramic Speed’s new ADR pulley wheels, which can go into regular derailleur cages. The saw tooth profile in the middle of the pulley wheel is for clearing debris, which is claimed to reduce bearing wear. (Image Credit: Liam Cahill)

Wove is a small and very interesting saddle brand which designs with a bike fit-first approach. This is the Mags, a 125g road and gravel saddle which we will definitely be asking to review. (Image Credit: Liam Cahill)

It was interesting, at Sea Otter, to see a number of brands from outside of the typical cycling sphere. Adidas was one such brand and having recently signed a deal with Mathieu van der Poel, I’ll be interested to see if more road and gravel products will materialise. A pair of these Velosambas have been on my wish list for a while. (Image Credit: Liam Cahill)

Big tyres on the road have been an interesting tech innovation this year and while Pirelli has lead the charge, not many brands can match their 40mm road tyres. (Image Credit: Liam Cahill)

They also had a P Zero F1 tyre on show which, as a casual fan of those very speedy cars, was rather cool to see. (Image Credit: Liam Cahill)

I’ll finish by getting back to actual cycling tech and POC launched their new TT helmet a few days ago. There are two widths to accommodate different shoulder widths, but how do you photograph a TT helmet? You ask one of the POC employees to adopt a mock TT position, of course.
