Alex Rims and A-Class wheels had a few unique new items to show off for both mountain and road bikes, unfortunately they’ve asked us to remove images of the prototype hookless road bike rim for both standard and tubeless clinchers since there are no plans for production.
As far as things actually available now, the new A-Class Karves wheelset uses a T-bar system to hold the spoke nipples. The benefit is that the spoke tension is spread across a much larger area, and they move freely, so the spokes are always facing directly at the rim with no binding or undue stresses. They say this improves stiffness and durability….
It’s 28mm wide, 25mm inside, with an unbroken tire bed so there’s rim tape requires to use the UST tubeless bead.. They now have an XD Driver Body available, too.
It’s available in all three wheel sizes with weights of 1682g (26″), 1730g (27.5″) and 1806g (29er). They’re compatible with all three front axle standards and QR and 12×142 rear.
Supra 35 is a new DH rim with 35mm wide rims. It’s around 550g for 26″, and it’s likely they’ll have a 650b size in the near future.
