Has anyone had any issues with these wheels being.. Flexy ?
I have my rear wheel (R65) laced to a Carbon-Ti X-Hub, 24h, rim brake. When I first installed it, there was a noticeable amount of side play with the skewer tightened up (both 4mm bolt on and the OEM QR skewer). Descending at 70kph, the rear wheel felt super wobbly and unstable. We're talking nearly 2 inches of side play
I've since loosened the grub screw, tightened up the bearing preload with the finger tightening adjuster and retightened the grub screw... But I can still pull the rim side to side going back and forth to each brake pad (1"of play..)
Has anyone else had to adjust this on their new rims? I've put 850km on them since May 1st and it feels kind of **** after spending $2k on my first ever brand new wheelset

$2k wheelset from LB? I haven't seen anything in their offerings for that much. I guess I don't know much about those hubs, but it otherwise seems that you get their high end topping out around $1200 or $1300

Just to be clear, we're talking "play" and not "flex" right? Those are two very, very different things.

No problems with flex at all. Did you build the wheel or did they?

That's quite obviously not an issue with the rim. If there's play in the wheel, it's a hub issue. Carbon-Ti hubs are top tier as far as I know, so I'd say take it to a shop or get in contact with carbon Ti.

It's side to side play. I'm not sure if I'm strong enough to flex wheels, the most power I can put down is about 800 watts

It's on a pretty standard bike for spacing (specialized roubaix) so I doubt anything is amiss there.

Power doesn't cause lateral flex, weight does. If you're pretty heavy and like to throw the bike around, you might see some brake rub, but you wouldn't be able to replicate that by hand.

Even then, that's really more a hub to dropout/fork relationship. I run centreline X rotors on 350 hubs on my roubaix as above and im 123kg and can drop 1400w in a sprint. Haven't had too many issues outside of wet rides.

This is side play, the kind that doesn't feel good! The rear wheel wobbles noticeably on downhills.. I've tightened up the hub a bit and did some more 75kmh descents, it felt OK.. Side play is less significant but still way more than past wheels. I guess I'll continue tightening progressively, and see how it goes

I haven't had any flex on mine, AR46 with a satin finish. They've been great wheels so far (well, until last week). I went with the cheaper Novatec hubs but I'm impressed, roll really well. I've also embraced Tubeless, wasn't as bad as I thought, easy to mount, didn't make too much mess and they feel great. However, I was slowly rolling along on a ride last week when a front spoke suddenly broke, pretty sure I didn't hit anything either. They're at the LBS now getting fixed, I have a feeling that the spoke may have been over tightened but I'll ask when they're ready to pick up.

Arrow straight so far. love them. I am around 66kg and only use them on the road. I use the OEM alloy wheels that came with my bike for gravel.

I never put up a picture of my WR50s I got a month or two ago .. so here they are! (not on bike now, use your imagination :-)). These have been an awesome gravel riding wheel set with tubeless Conti Terra Speed 35c on my 2020 Roubaix.
If you are getting these wider rims I would also go one step deeper, they have much less wind buffeting side-to-side compared to my Rovals which are also 50mm (more slope to wheel due to thickness means won't catch side gusts as bad). I am happy with these but if I was a racer I would have gone for the WR65.

I bought an 88mm rim on Ebay and laced it up to a 24 hole track hub. When I rode it, it would make this clicking sound, which I think was the rim smacking against the valve extender. I bought rims from the same seller before in 50mm and it was fine. I think for the 88mm rim, the manufacturer did not take into consideration the issues you are referring to. I bought a Boyd 90mm, problem solved. I also have never had that issue with my 808 wheelset.

Finally got around to taking a decent picture of them (AR45). All good with an Everesting and a bit more than 1000mi/1700km on the wheels.

I posted this in the What did you just buy for your gravel bike? thread but thought I'd put this in the "official" Light Bicycle Wheels thread.
I just got my wheelset and had it set up on my Santa Cruz Stigmata.
Light Bicycle Falcon Pro - WR38 Disc - 24H - Hooked Tubeless:
It's hard to be subjective over just one ride but it seemed a bit easier to get to speed and maintain it. I do notice bit more side force from cross winds because of the deeper profile compared to my last rims.
And of course as the mechanic I use told me when I picked it up - "they look the business". Love how my bike is set up.

That's a nice setup all the way around, KJ43. How much did they run you? The shallower depth rim is probably the best all around. I have a set of WR50s on DT240s on my road bike that have about 3000 miles on them now, and they can be a little dicey in a strong crosswind.

These still have a deeper profile than my last alloy wheelset so I feel the winds a bit more, but it's still not bad at all. I'm really enjoying them so far and I'm really happy with my purchase.

Are there any reviews of the LB Falcon Pro AR465 yet? I couldn't locate any.
I'm trying to decide between:
a.) AR56
b.) AR46
c.) AR465
Haven't decided on hub, but thinking DT350 as weight isn't a priority, since my locale is pretty flat and I will be riding a Canyon Endurace. Aero would make a bigger difference overall for my rides, but this being my first carbon wheel set, not sure how much of a difference the depth really would make between the three options. The roads are good, but any of the above with a 700x28 GP5000 TL should give a good ride from what I've read.
I'm a heavier, but largely inexperienced rider at 106kg. I don't have a large amount of kms under my belt, maybe 5000 total, but most of that experience is pretty far in the past. I do maintain 32-34 kph on my solo rides, unless I'm pushing the distance, which for me is usually as far as I can manage in a few hours before it gets too insufferably hot. Most of my rides are relatively short 1-2 hours and as fast as I can manage, with the odd 100km ride here and there if I'm feeling froggy.

FYI... I ended-up buying a Kool Stop Tire Bead Jack which made installing tight tires considerably easier. I didn't even know this tool existed until I nearly broke myself trying to get GP5000s on my wheels and someone here recommended the tool.

What are the benefits of upgrading wheels alone rather than re-sell the bike and upgrade for a bike with better wheels? I mean, is there a financial benefit to upgrade the wheelset rather than the bike? What do you do with the original wheels? I'm a noob, sorry for the basic questions.
