Parcours says the new 650b version of its Alta wheelset is for those “seeking a ‘one wheel’ setup for their gravel bike”, thanks to its lightweight build that boasts 35mm deep aero profile wide carbon rims.
The new 650b wheelset (£849) is designed for those mixing it up on both the gravel and tarmac, with the robust build said to “thrive on exploring the most rugged of trails, and yet is also just at home powering along the flats, with responsive handling”.
Down from the 28 spokes of existing 700c’s to 24 spokes, these tubeless ready wheels are promised to still be “robust enough for whatever you throw at it”. The spokes are laced in a two-cross pattern both at the front and rear, to an aluminium hub with EZO cartridge bearings as used in the 700c’s.
With this, the 650b versions are lighter and come in at a very respectable claimed weight of 1,360g for the wheelset (605g front, 755g rear), whereas the 700cs were 1,494g.
It features the same 35mm deep aero rims which impressed Dave Arthur with their strength and stiffness for the price when he tested the 700c version earlier this year. His full review can be found here.
With a wide internal rim width of 25mm, these hookless rims are said to be well suited to “the most animated off-road routes” and are designed to be wrapped in wide gravel tyres, to maximise comfort and traction over the tougher terrain.
Set up for commonplace 12mm thru-axles, adapter kits are also available to fit various other axle standards.

Yep. Either newly signed up or a PBU.
Probably a good reason not to drive like a knobhead then?
I'm all for looking at ways to minimise traffic collisions, but some incidents are so rare and difficult to mitigate that they're not worth dealing...
I had done something sort of comparison, when I started carrying my D-Lock on a bike mount and the bike seemed to be obviously slower to change...
That's just for disc brakes though. Stops them squeaking
Is this to do with the country? I would have thought most people walk a bike from its left hand side to avoid the (in my case, mucky) drivetrain.
The ultra-slow-motion, close-up replay of Tadej’s front wheel tire puncture and low-speed crash may be the beginning of the end for hookless wheels...
For small riders, I believe 28 wheels would be faster than 26, otherwise we would see them on pro racers, especially when 26 exist on such cheap...
I'd anticipate that the busier junctions aren't that appropriate for cycling through red lights, but I do encounter plenty of less busy junctions...
A bit tangential but I love this one...
