"Inspired by 19th century carriage drawn artillery...."

Those...?!forks?! Are going to slice up any pedestrian they hit at speed

Looks quite uncomfortable.

These aren't 'cycles' per se though - no peddling......are they not electric 'bikes'?

I'm sure there's only one size at the moment but it looks uncomfortable / off balance to ride.

From the first image I thought they were balance bikes for children. Owlet is a cute name.

A owlet is a baby Britten?

Can’t make the image links work properly but one of those old school metal foot pumps.

Do we need to talk about these?

Another “industry standard”

It's finally here: the long overdue development that makes inflation easier for everyone!

Get fucked!

I think Presta isn't great as it goes.

The pin can get bent, the valve head can come out with twist on pumps, there should be a better way.

True, Schrader is a much better valve, 10billion + cars can’t be wrong can they. Presta was only because bike rims used to be so very very narrow

Lol, Presta > Schrader for bike tyres, no contest.

For a start, when you inflate a Schrader valve, you have to push air past the valve spring, in addition to fighting the pressure inside the tube. And rims have to be pretty damn wide before a dirty great Schrader hole isn't a weak spot...

Fat valves also look shit and aren't even trying to be aero. And when you want to put a little air in the tube to give it some shape so it doesn't get pinched on installation, you can do it with your mouth via Presta.

Furthermore, Presta seems French and Schrader seems American, so an easy win on that metric alone ;)

Also, bent valves is yet another thing to handily separate clumsy noobs from those in the know.

But you can set up your tubeless tyres up at the petrol station for 20p ;D

TL is the argument for Schraders. I think that point was made a few years ago on one of the MTB sites. Bigger valve stem for easier filling with sealant, less blockage risk. I guess why someone then came up with those "new" style valves that I can't remember the name of but cost £25 each or whatever

Schwalbe say that 50% more air goes in. Which would be great if true.

Another version is a combo of the two

People are still bothering with the epic hassle of road tubeless? I thought that was just a silly fad.

I've had a go on those Schwalbe valves. They are really good. It seems to combine the best of both common valve types. Easy to stick a pump on, really good flow, small profile... Not yet sure how they'll hold up to dirt and sealant.
But really, unless they convince other OEM manufacturers to get on board, it'll be a hard sell.

I've used Reserve Filmore valves on the past couple of tubeless setups I've had and they're bloody great. Helps that I've got a friend that can get them on the cheap, but there is a tangible difference between them and normal presta valves.

They're the ones I was thinking of. Think bikepacking.com did a review a while back.

Okay, those new valves look like the bomb for tubeless.

Since I have no interest in tubeless though, happy to keep using my 1880 tech.

Thoughts?

Thoughts?

Will go the way of the Browning and Vyro, but without even making it as far as production.
