Is this CHPT3 collaboration the coolest Brompton yet? Plus tech news from Cube, Ritchey, Silca, Chapter2, Mission Workshop & more

Check out all of the week’s top tech news, including a brand new gravel bike, a limited edition frameset from Ritchey, anodising where you never expected it, and the accessory that’s like ‘sitting on a cloud’... allegedly

We have loads of new stuff to tell you about this week from the likes of Cube, Ritchey, and Silca, but we’re starting off with a very cool collaboration between Brompton and CHPT3...

Is this the coolest Brompton yet? Stripped-back CHPT3 collaboration weighs 9.5kg

Brompton has teamed up with CHPT3 for a fourth collaboration, taking the well-respected P Line model and giving it a stripped-back look and some special features.

Brompton and CHPT3, led by ex-pro racer cyclist David Millar, teamed up previously in 2018, 2019, and 2020.

“The latest bike features selected proven performance modifications such as titanium forks and rear triangle, assembled for speed without loss of comfort,” says Brompton.

You get a titanium rear frame and fork on a regular Brompton P Line too.

“The bike’s stripped-back look without mudguards or front luggage is finished off with lightweight inner tubes, a low profile handlebar, ride anywhere 4-speed gearing, Black Edition finishing kit, and a limited-edition Frame Pouch Bag as standard,” says Brompton.

That Frame Pouch Bag looks about the size of a small saddle bag, handy for squirrelling away a multi-tool, spare tube, and so on.

The Brompton x CHPT3 4th Edition wins more cool points with a short-nosed Fizik Terra Argo X5 gravel-specific, designed to absorb vibration,  and tan-walled Schwalbe One tyres.

The complete bike is said to come in at 9.5kg, about 500g lighter than a Brompton P Line Urban.

It has a fight on its hands to take the title of coolest Brompton ever, though. The titanium T Line bikes weigh as little as 7.45kg and look very, very neat, although they’ll set you back north of £4,000. A Brompton x CHPT3 4th Edition is £2,595 and is available now. 

If you want to go the whole hog, you might remember that CHPT3 launched what it called the “world's first cycling shoe engineered for riding in the city” a couple of weeks ago. With grey and red details, these are designed to match the bike.

It's going to be a right old Brompton-fest on over the next few days. Stay tuned for reviews of the Brompton Electric P Line tomorrow (19th February 2023) and the Brompton C Line Explore next week.

Ritchey introduces 50th Anniversary Outback gravel bike

Ritchey has released its Outback gravel frameset in a 50th-Anniversary limited edition Half Moon Blue finish. The brand announced its Logic and Swiss Cross framesets in similar limited editions earlier in the year. The Outback is TIG-welded with proprietary triple-butted Ritchey Logic steel tubing.

“The frameset retains everything the bike is known for,” says Ritchey. “It sports several practical and adaptable features that offer riders the ability to chase epic ride experiences beyond the end of the road and the end of the day.

“Rack and fender [mudguard] mounts help to keep things dry and expand the load-carrying capacity for longer bikepacking adventures, while clearance for 700c x 48mm or 650b x 2.0in tyres opens up a whole new world of possibilities. The frame accepts flat-mount disc callipers, and the all-carbon fibre Ritchey Adventure fork with multi-purpose mounts on the legs gives you more places to stow the supplies you gathered at the last cafe.”

As well as the light blue to dark blue fade paint job, the 50th Anniversary limited edition features logos that reference the Ritchey’s history.

The Ritchey Outback 50th Anniversary frameset is priced at £1,435.90.

Silca offers anodised titanium bottle cages – and straws – for £190

In most editions of Tech of the Week we bring you news of something you didn’t know you needed at a price you can’t believe. We wouldn’t want to disappoint you this time around…

2023 Silca Sicuro titanium bottle cages straws - 1 (2)

Silca is offering a set of two Sicuro titanium bottle cages and two titanium straws – anodised in Matte Bourbon, Rainbow or Royal Purple – for £190.

We reviewed the Silca Sicuro bottle cage here on last year and found it to perform really well, but titanium bottle cages are never cheap.

> Check out our Silca Sicuro Cerakote Titanium bottle cage review

2023 Silca Sicuro titanium bottle cages straws - 2

It’s the straws that intrigue us. You get a straight one and another with a bend. Maybe if you’re anodising anyway, you might as well do a couple of, you know, straws. I guess.

Cool colours, though.

Chapter2 debuts Kaha gravel frameset

Chapter2 – not to be confused with CHPT3 (above) – has introduced a new gravel racing frameset called the Kaha to sit alongside its existing Ao adventure option.

“The Kaha has been designed with performance in mind, working seamlessly with the Mana Grvl bar to create a gravel racer with all the cables and hydraulic hoses concealed within the frame and handlebar,” says Chapter2.

Cube unveils CMPT bike trailer that doubles as a kids’ buggy

German bike brand Cube has launched a bike trailer called the CMPT that doubles as a kids’ buggy when you get to your destination.

Does this inflatable seat cushion provide “the ultimate comfort”?

We’ll answer our own question right away: probably not.

2023 Kickstarter BC-352 inflatable seat cushion - 1 (1)

There are loads of bike saddle covers out there designed to improve comfort, usually aimed at beginners, but they tend to be squishy and unstable. We’ve not known many people who have stuck with one for long.

A new design has just hit Kickstarter that uses an airbag to make it feel like you’re ‘sitting on a cloud’. Allegedly.

“BC-351 adopts [an] ergonomic 3D airbag design, which cannot only maintain full elasticity and comfort when sitting – creating an ‘anti-gravity’ effect of even compression, cushioning about 80% of the body's vertical pressure – but also perfectly bear the hip and waist pressure during riding, protect the rider’s hip and waist health and reduce unnecessary consumption [of] exercise while riding comfortably, and ensure longer riding time.”


The air cushion is said to be “self-inflating” but the video shows that you pump it up with your thumb.

You have to pledge at least HK$149 (about £16) to be in line for one. The project has already well-exceeded its funding goal but we’re going to give it a wide berth.

It's a v cool Brompton.  What I like about the Ch3 marketing pitch is that it portrays the image of a person in everyday clothes using a folding bike to get around, as opposed to the usual lycra/high-viz image that alienates a lot of people.  That said, it'll probably be die-hard n+1 cyclists that shell-out for one.

Considering how difficult it is to bend TI tubing, I can only wonder why anyone would want to mass produce these.. I guess the difficulty level is reflective in the price.. however as there is the magnificant sum of zero benefit of a TI bottle cage over another lighter, less costly, or even exactly the same looking bottle cage.. it begs the question.. why would anyone in their right mind buy these? Surely these belong in the same group as Rapha silk scarves, Mavic slippers and Campagnolo coffee tampers.

I bought a Brompton in 2020, at the time, the superlight option (now called P Line) comprised of Ti rear triangle and forks, with a weight saving of around 750g - for a price premium of around £750 over the price of the standard model. £1 per gram - and IIRC about 200g of that was down to the fact that the Ti rear triangle didn't have the pump attachment lugs and therefore no pump. 

So went for S6L Black Edition in black (S6L = low bars, 6 speed, mudguards no rear rack), and blinged it with upgraded grips, anodised red hinge clamps, larger extended Eazy Wheel roller kit, Conti tan walls, front carrier block, folding basket bag, tool kit, etc. Total cost inc upgrades around £1400, weight approx 11.5kg.

Inflatable seat cushion has missed a trick.
