Brakes fitted under the chainstays is not new, MTBs bike tried that out 15+ years ago. It never took off, can't recall why but could have been the time v-brakes came into existence.
Aesthetically I think the brakes look nicer tucked away under the chainstays but am not convinced from a practical perspective. The brake will be hit with any spray and debris flung up from the front wheel even with mudguard fitted.

I don't think the fact that it wasn't successful for mountain bikes is relevant, the fact that it was tried shows there were some advantages, my point was that it has potential for a summer bike, there are no mudguard eyes fitted.

Does anybody have any info on the wheels? From what I have seen they look very similar to Mavic Aksium.

I believe they are B'Twin wheels, but are significantly better quality than the ones that come with the budget bikes.

Agree on potential for a summer bike and the chain stays will certainly be more rigid than the seat stays so you'll get greater braking efficiency/effectiveness. I made the MTB reference to highlight that moving the brakes was not some new fangled concept or idea.

The fact that it was tried shows that someone (marketing or engineering?) thought there was some advantage. If it was tried 15ish years ago, and has not been widely adopted yet, perhaps it was more a marketing decision?

Perhaps the rear brake position is a way of avoiding problems of running a cable along the curved top tube rather than going for internal cabling.

There are sound engineering (and aesthetic) reasons for putting it there,the fact that it is more exposed to muck thrown up from the front wheel make it unsuitable for mountain bikes and with road salt in this country winter bikes. Whether it becomes widely adopted this time depends on how many manufacturers redesign frames to use it and is more to do with marketing than engineering, which I suspect depends on it being seen on 'pro' bikes.

If the engineering reasons for mounting rear brakes there were compelling, wouldn't the manufacturers have redesigned their frames sometime in the last 15 years? I suspect the "pro" look will soon be disc brakes sometime soon, and I'm sure that look/feature will filter down to regular road bikes. When you see how common discs are on MTB's, I'm sure they will (rightly or wrongly) arrive on road bikes.

I'm inclined to agree about discs, while the Alur is tempting, my other thought is waiting for discs, but how long and at what price? The thought of getting light rims that won't wear out is the main appeal to me, rather than increased braking performance. The problem is discs just don't look right on a road bike.

I was watching one of the tours recently and they mentioned those types of brakes. I seem to recall the commentators saying that it was tried by one of the big manufacturers recently and they reverted back to the traditional positioning of the rear brake. It may have been Giant that they were talking about. They said wind tunnel tests showed no advantage on the positioning.
When I first saw the spec of the Alur, it all looked good until I read about the rear brake. I'm not convinced at all, especially on UK roads in winter. I'd have though corrosion and performance would be a factor.
We do have to consider that they are not solely produced for the UK market.

I read this recently. The main problem seems to be making a wheel capable of handling the forces involved that is light enough to go on a road bike.
