I'd take the old ones over the new ones even at full price.

Just out of curiosity, why?

Anyone here would have a review of the AR24 model for ROAD use?

I wanted to build a new set of lightweight wheels as I'm currently running the AR56 (not too porky at ~1550gr) and I wanted a set for sustained climbing. I'm concerned about the rims being only available hookless as I have no experience with this setup. I run my GP5K TL 28mm at about 70-80psi (I'm 78kg) and I don't think I could go much lower, but LB recommends 20-40psi...

Should I be concerned with potential blow-off?

djel, Continental says don't. It says on the tire.

Happy much-belated birthday to me. Ordered placed on June 15th, wheels arrived from China on August 3rd w/ FedEx shipping. WR50s with flyweight carbon and a bit of bling-bling 'cause we all know that a bit of bling makes you (psychologically) faster 8)

I quoted my current tires for the tire pressure reference only.

recently acquired a pair of Falcon Pro WR38 disc wheels. They are beautiful! And seem well constructed. I asked LB, whether they would be making a hooked, rim brake version of these rims. Their reply was only if interest from users is high. Anyone looking for such a rim should message LB!

any one know the reason why some wheels are listed at such low MAX PSI such as the AR45 list at 60psi MAX.
Is that for safety? So use to seeing all other carbon wheels near the 100psi max

Any suggestions on what medium depth gravel/road wheelset to buy?

I have a Focus Mares CX that I will be using for fast gravel roads and fast group rides on 35mm Gravel King slicks. I've been looking at the WR45 which seem to be a versatile option with 25mm inner 32mm outer. Budget is on the lower end: Novatec D411SB hubs, sapim cx ray, ud matte. Hook/hookless?

Thanks!

Pretty sure they dropped this recently. I asked about the AR45 specifically (mine should arrive any day now) and got the following response from them:

Do you use 25C? Actually, our final tire chart is not finished yet.
We will update better tire pressure recommendation for different weight riders and different tire width.
​If you ride 25C, the tire pressure can be 95psi~120psi
If you use 28C, it is better to be less than 60PSI

Sheesh. Their guideline makes no sense. If the wheel can handle 95 psi with a 25mm tire, it should be able to handle more than 60 psi with a 28mm tire. The hoop stress of a 25 @ 95psi is the same as a 28 @ 85psi.

Hoop stress is linear wrt pressure and diameter, so if a 28mm has a 12% larger diameter than a 25, the pressure must be 12% lower to maintain the same hoop stress. Of course this is a rough estimate since the the wheel is not changing size only the tires.

I'd go with hooked, much more versatile and also easier to use with road tires or higher pressures.

These look good!
Nice weight too!

I'm desperatly waiting on the WR38 flyweight rims I ordered on June 16th, but they are still in "processing" :(

Bit odd. I ordered a WR 38 flyweight on 17th July, and it's gone through all the steps and is now in QC according to the tracker. Maybe worth checking with LB?

"If the accessories (hubs, spokes, or nipples) are out of stock and will be ready over 2 weeks, we will double check if you would like to change the accessories or wait for it."

My wheelset was stuck at processing status because they ran out of hubs.
