wide rim brake tubeless rims for big tires?

Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza".

wide rim brake tubeless rims for big tires?

I am running 45 and 50mm tires on kinlin 279s (23 outer 17mm inner width) in a Trek 750.
I am not sure if they work tubeless, I am not really the experimenting type.
These rims are about 500g each, I am thinking of getting a new wheelset with a lighter tubeless rim. I also want to use these rims for my tubed clement tires anyway.

Stans 340 (~390g rim weight) seems like it fits the bill, but it isn't any wider and not sure it is strong enough for off road riding, maybe in 32h?

There are some old model Pacenti SL23s on sale (24 outer 18.5 inner, 440g), again, not sure if strong enough for off road. seems like only 24h and 28h are available, but I could probably get away with 24/28 at my weight.

bdop has the kinlin x31 (24 outer 19 inner, 490g) in a 24/28 or 28/32h kit for $320. not sure if the hub will withstand off road, but rims look tough

anything else? looks like all the really wide 29er rims are disc brake only...

regarding 24F/28R spokes...

how much do you weigh, and do you ever bunnyhop your bike or do even 'easy' singletrack trails?

SL23s are a strong rim. I've raced CX on them with 43 mm tires with no problems. The 24h spoke count is possibly a concern (mine are 32h) but you could always just get a pair of 28s.

I think you'd be fine with 24/28 based on that.

Thanks, I found a set of pacenti rims in 20/24, inner in 18.5mm. maybe with some strong hubs.

I was also looking at the HED c2 plus rims, 25 outer ~20mm inner, may be better for the 50mm tires.

I might get the pacentis anyway for my 40mm clements that are sitting around without a wheelset...

I don't get what strong hubs have to do with it.

P.S. Velocity A23. Widely available in a range of hole counts. Off-center version for a stronger rear wheel.

I don't recommend the A23 for cyclocross. It is floppy and soft. And Velocity has had QC issues in the past. You can get better rims for the same price.
