Would you wear an inflatable bike helmet? Plus SRAM Red sneak peek + new shift button, a base layer designed for riding over 30mph, Brompton x Bear Grylls + more

Check out loads of new stuff from Trek, Suplest, Chrome Industries, Rouvy…

We’ve got another packed edition of Tech of the Week for you, featuring what looks like SRAM’s next-generation Red groupset, Brompton’s collab with Bear Grylls, your chance to ride virtual stages of the Vuelta a España, and earbuds designed with cycling in mind, but we’re starting with a very, very unusual helmet…

Have you seen the Inflabi inflatable bike helmet?

In terms of appearance, it’s a challenge but could the Inflabi inflatable bike helmet offer practical benefits for urban cyclists? (We first saw this product on Cyclist’s website although it was at Eurobike earlier in the summer).

2023 Inflabi helmet - 1

If you think this looks like something you just pump up and stick on your head… well, yeah, that’s pretty much the size of it.

“Unlike classic helmets, the bicycle helmet is not made of EPS foam, but consists of robust textile air-tied chambers that use our air technology,” says Inflabi. “When filled with air we can achieve a better shock absorption in case of a fall.

“We use inflated air chambers to provide unparalleled safety and protection for cyclists. Our unique design uses abrasion-resistant high-quality fabrics and a specialised membrane to create air chambers that can be easily inflated before use, providing a custom fit and maximum impact absorption.”

The only existing design we can think of that does anything even vaguely similar is from Hövding, but that’s an airbag that you wear around your neck, automatically inflating to cover your head if you fall.

What’s the advantage of an air-filled design?

“[It is] lightweight and flexible, comfortable and adaptable,” says Inflabi. “If you don’t need Inflabi, deflate it in seconds and store it in your pocket.”

Inflabi says that when deflated, the helmet packs down to 15% of its in-use size and that it’s reusable after a crash “as air does not break”. Obviously, it has to be inflated to a certain pressure to be fully effective. 

There doesn’t look like a great deal of ventilation going on here but Inflabi says that will come.

You can’t yet buy the helmet but Inflabi is continuing to develop its product, moving away from its original ‘orange peel’ look – as shown in the image at the top of the page – to a design that offers “a more sleek and a more comfortable fit’.

“We are currently working towards getting the certification for the Inflabi inflatable bike helmet,” says Inflabi. “This involves undergoing rigorous testing and meeting industry standards for safety and performance.”

Inflabi’s Julian Wiebke says, “It’s not on the market yet. However, we will probably do a presale in Q4 this year and are planning to ship in Q1/Q2 next year. The price is probably going to be around €150.”

That converts to around £129. We’ll keep you updated on progress.

Is this a sneak peek of SRAM’s next-generation Red AXS groupset?

SRAM could be planning to offer a new shifting option when it introduces its updated top-level Red AXS groupset, giving you a thumb button on the side of the lever body, judging by a just-published patent.

2023 August SRAM shifter patent  - 2

There have been rumours about a new version of the SRAM Red groupset for months now with previously unseen shifters having been spotted as long ago as last December, although SRAM hasn’t officially said a thing about it.

> New SRAM eTap AXS shifters spotted: is a new SRAM groupset on the way, and what do we want to see from it? 

Pro riders have been seen using shifters with hoods that are noticeably smaller than those of current-generation Red – more in line with SRAM’s third-tier Rival eTap AXS groupset and the recently released version of SRAM Force AXS – on top-end race bikes.

> New SRAM Force AXS first ride review — is it any good? 

Now a patent for a “Control Device For A Bicycle” that has just been launched appears to show similar shifter architecture but with an ‘auxiliary button’ positioned on the side of the lever body – up at the front end, which SRAM calls the ‘pommel’.

“The auxiliary button may be connected to a shift lever paddle printed circuit board (PCB) via a cable that is routed and retained on the body of the control device through a channel within the body of the control device,” says SRAM.

2023 August SRAM shifter patent  - 1

This auxiliary button – which you should be able to find easily because there may be a convex or concave dome or rectangle in the outer cover to indicate its position – is designed to provide “additional functionality and ergonomics”, according to SRAM.

For what, exactly, would the auxiliary button be used?

“Activation of the auxiliary button unit may initiate the generation of signals related to shifting, pairing, derailleur trim operations, power management, one or more other actions on the bicycle, or any combination thereof,” says SRAM, in typical patent jargonese… but you get the idea.

“For example, the controller of the PCB may be configured to generate signals to control the front derailleur and/or the rear derailleur in response to a signal received… when the electrical switch is activated by the rider.”

It sounds, then, like this auxiliary button could be used for setting up the system – getting the indexing correct – but perhaps for shifting too. The shifter that sits behind the brake lever is still there, of course, it’s just that the auxiliary button provides an extra option, as the name suggests.

2023 August SRAM shifter patent  - 2

This auxiliary button sounds a lot like the button you get on top of each shifter hood with Shimano Di2. These buttons can be used to change pages on your cycle computer and they can also be configured to control your shifting. Is SRAM planning something similar? As usual with anything patent-related, we’ll just have to wait and see.

What features would you like to see included in SRAM's next Red AXS groupset? Let us know in the comments.

Check out Remco Evenepoel’s 6.8kg Specialized Tarmac SL8 for the Vuelta

Could this be the bike that’s ridden to victory in this year’s Vuelta a España? Although you’d be brave to bet against the Jumbo-Visma pairing of Jonas Vingegaard and Primoz Roglic, Soudal–Quick-Step’s Remco Evenepoel is likely to be there or thereabouts and here’s the Specialized S-Works Tarmac SL8 he’ll be riding.

Trek adds new Project One paint scheme

Trek has introduced an all-new Icon premium paint scheme to its Project One custom bike programme. Crystalline Prismatic “creates a prism effect and refracts light in multiple dimensions”, according to Trek.

2024 Trek Project One Crystalline Prismatic  - 1

“This handcrafted scheme is made by fusing thousands of tiny crystals into organic lattice structures that radiate in any light,” it says. “Due to the organic nature of the Crystalline paint process, no two frames are the same.

A base layer specifically designed for riding over 30mph. No, really!

Although the concept of an aero base layer might sound odd, we’ve been hearing a lot about this latest marginal gain over the past few months and Rule 28 has just launched a new offering that’s said to be optimised for high speeds. It’s all about the ribbing, apparently.

2023 Rule 28 High Speed Base Layer - 1

“Our original Aero Base Layer is a fantastic performer for speeds below 50kph [31mph]…we’re thrilled to see so many elite riders choosing it for road racing and time trial races,” said Sam Calder, founder of Rule 28. “But we know there is an appetite for purpose-designed garments to suit the specific needs of road sprinters and track racers operating at speeds exceeding 50kph. It’s not a base layer for everyone, but for those racing at these high speeds, it’s a game changer.

> Has aero gone too far? The most excessive cycling tech made to shave milliseconds 

Rule 28 says that the High Speed Aero Base Layer is “the result of the rigorous testing of numerous prototypes, each featuring custom fabrics with a range of rib spacings”.

“The theory behind how two-layer aero technologies work predicts that different rib spacings will yield optimal performance at different speeds,” says Rule 28. “The narrower spacing of the ribs in this High Speed Aero Base Layer, when placed underneath a skinsuit, proves more effective in reducing drag above 50kph.”

If you’re sceptical, Rule 28 publishes all aero testing results and data online. You can check out the details here

Like Rule 28’s original Aero Base Layer, the High Speed Base Layer costs £149.99.

Are these the cheapest DIY bike panniers out there?

There’s nothing new about making panniers out of plastic cans but RackHackers have just produced a video showing you exactly how to do it.

They even provide a parts kit

“We spent two years designing and testing, to make it as visually appealing and functional as we could, based on what we learned in 10 years, using different versions of it,” says RackHackers’ Andras Booker.

“During the design process, we committed to only using parts that can be found in hardware stores, or easily made, for people who prefer to produce it themselves.”

Cute. Whereas of course EPS does "break", in as much as it does not rebound after being compressed, which is precisely why it works. For the same thickness of deformity, EPS brings your head to rest whereas the air bladder will go on to propel it back in the return direction, doubling the overall acceleration to the brain. The same reason that actual "air bags" deflate under impact (having inflated in the previous instant).

That assumes that the air stays in there. Is it possible that it does deflate similar to airbags via one of the two green valves on the back?

Brompton Bear Grylls collab?  Sounds terrifying - I can imagine the bike suddenly dives off the road and over cliffs / into a swamp, picking up animals in its spokes and throwing their raw guts into your face.

Although to be fair once folded it's probably an extremely effective means of silently disabling any Russian paratroops you may encounter.

I want to see the Ray Mears version - sturdily built, not as fast but takes you through any terrain comfortably.  And with a decent respect for local tradition!

A Brompton does seem like the ideal bike for Bear, precisely because you can easily fold it up and take it into your hotel room.

Kinetics in Glasgow will make a Brompton for off-road use that will still fold small enough to take into a hotel room. Mayne he should talk to them.

Seems like those people who drive combustion powered vehicles in the UK are utterly irresponsible rat bags,in their behaviour towards road cyclists. Inflatable helmet? What about an inflatable suit,similar to that of the michelin man.

Rat-bags in rat-traps, since the traps kill the rats as well as we hedgehogs on our bikes! But I can't wear an inflatable suit, as I try quite hard on me bike and already get a bit damp as a result.

 Wot I'd like, from bicycle gubbins inventors, is not some awful paint job on a £12,000 bike that's impossible to change a cable on but, rather, a small canister containing a special gas that will enter any and all combustion engines, gradually causing them to seize up beyond repair. The canister will live under the bike seat, out of sight; and the gas will be invisible and otherwise harmless, especially to hedgehogs on bikes.

A new law will also be passed concerning car-litter. This will see the towing and mincing (for new bicycle manufacturer feedstocks) any car left on the highway for more than 10 minutes. The seized cars will thus all go to a better purpose (new bikes!) and there'll also be the beneficial side-effect of getting rid of all those cars parked on the public highways free of charge, making the place look like an American slum. It'll lessen the chance of being doored in suburbia an' all.
