does anyone know if these wheels have cartridge bearings or are they cup and cone?

I just got a pair of the 35s on a new bike.
The front wheel didn't feel particularly light but that might be the weight of the disc rotor.

I need to check with the shop as I think there are some bits missing - but there were no valves to make them tubeless.

Anyone know if they should have come with the bike or whether i just need to source some third party valves?

I've not measured them but if I compared the total bike weight compared with my farsport feeders (1250) and adjusted for different tyres they're around 1550 - 1600 including rim tape I would say. I will also add they're quite a tricky rim to get tyres on as well!

I ve seen them listed online for 1635gr and 1540gr in different sites. Havent had a chance to weigh mine, but hoping that they are on the heavy side so that i ll get some significant reductions when upgrade time comes.

Worth also bearing in mind there's a non-sl knot 45 and that they changed the hubs from dtswiss to formula hubs for the 2021 models from what I can tell so this may effect things too.

They should come with the tubeless valves, they were in the box of miscellaneous bits (extra spacers etc) for mine.

I just got a set of these as well and there seems to be nothing out there about them. If the hubs are servicable they are pretty light. I am running them on a Cannondale Topstone.
