Light Bicycle wheel rims?

[Mr.Gib]

Would you consider WR40? It's Pro series for better rim finishing. Also, the workmanship of X-Flow type rims are improved over the non-XFlow.

Has this proved to be the case? Or is this just based on manufacturer specs?

If anecdote counts, I have built a lot of LB rims and the Falcon Pro X Flow stuff is to my eye and inspection a higher quality finished product. Outer surface, spoke holes, and bed/hooks. So much so I bought two pairs for personal use. Aero wise I have no idea.

Well that's a very strong endorsement given your background. How is the X-Flow in cross winds? My WR50 are surprisingly good. I need another set of wheels which will see use in high mountains where anything can happen. Was considering the WR38. Sounds like the X-Flow might be the rim if it's stable enough. (Must admit I struggle with the wavy appearance. Hate "gimmicky" looking gear.)

I’ve ridden them in strong cross winds with 32mm tyres, and while there is solid side pressure, it was not unmanageable. But I haven’t ridden in alps where there could be gusts as you twist around bends on high speed descents, or ride across peaks with extreme crosswinds.

Do you find the WR50 too deep in the high mountains?

It seems a new X-Flow will be launched soon? Turbo？Its look just seems more strength against gusts but no idea about aero effect. https://www.lightbicycle.com/newsletter ... etter.html

Wouldn't even consider taking 50mm wheels on a mountain trip - I have always have used shallow allow wheels. Deeper wheels might be fine most of the time, but I've been in too many situations where anything deep would have been very bad. I have seen people walking because of the wrong wheel/wind combo. I have had my WR50 in 35 - 40km/h winds and they were very good, but that's in manageable terrain near home. Descending a big pass in a thunderstorm with powerful gusts can be borderline with the shallowest wheels.

That's even stranger looking - I'm out. Major Kudos to Light Bicycle for pushing the envelope though. Very happy to give them my business.

It's cool that these companies are at least trying to innovate, but I wanna see some data to back it up

[alanyu]

I asked them for detailed pictures, and found that the direction is wrong. They admitted their fault in building the exhibition sample.

[toxin]

Could be a similar principle as the onirii rims? Whatever thats even supposed to be

Nvm I won't even bother trying to understand what these shapes are supposed to do

[alanyu]

I have no idea if this kind of sharp fin is useful or not, but if it could help flow separation, the direction should be opposite.

I will certainly buy this rim if the width meets my requirements and the general cross section is not off, purely for its aesthetics.

The conti Aero 111 might be interesting for someone like you to try to help mittigate crosswind impacts on handling. If you do please post your experience given it seems like you actually push your equipment and give real feedback

I understand that. Yet... If Zipp says "this is inspired in Wales" people will say "awesome" but if a Chinese company says what they said it is not believable. Just as specialized saying it's x amount of seconds faster. Or any other brand saying that their wheels are faster than the competition. All of those are claims that cannot be really verified.

But one does however he/she/they wants.

In my case, I try to get averages. If people with the X-flow 375 or 465 can confirm inner width, hook width and maximum width I'll be more than fine. On top of that which tires are using and their real measured width than it's just perfect.

The same goes for the wr40.

I am using ar375 lightweight option with carbon ti hubs.
Inner width: 21,8mm
Hook width: 28,9mm
Maximum width: 30,3mm
Pirelli pzero Race 28C (tubetype) come in at 28,7mm@5,3bar

Very satisfied how they handle in crosswinds!

Any feedback by now?

I am still very satisfied with them. I use them only in the mountains at the weekend and they perform just as good as the Bora Wtos did which they replaced

Hi, I'm looking for WAM tyre measurements for GP 5K S TR. Do you run these tyres? Looking at either a 28mm or 30mm, want to stay within the 105 rule.

Thanks for any help, no dramas if you don't have this info.

Damn, those hubs tho! 210 g for a set of non-side entry carbon spoke hubs.

24 mm internal 32 ext rims. Sub 1200 g for 50 mm wheel.

Sounds amazing on paper. The rim profile and LB's carbon spokes are the only questionmark for me

Boy do these new rims look da bomb.

I'm with Mr.Gib on this one after this year's Marmotte, where descending from the Galibier in those winds was something I'd rather not experience again (I was on 50mm Farsport Hypers there).

The conti Aero 111 might be interesting for someone like you to try to help mittigate crosswind impacts on handling.

Interesting idea, but I, for instance, would always prioritize grip (and wet grip! where Contis never really shine) over aero or even RR in the mountains.

At this stage I'd not recommend any wheel with carbon spokes plus generic/ODM hubs. My friend got AR565 with the latest gen LB carbon spokes and hubs. Not great at workmanship (bearing binding, echoed by Hamb1n1) and hub geometries may contribute to the draggy feel when climbing.

I wish one day LB will become a true wheel manufacturer with in-house designed hubs and rims. That way they can create something truly awesome.

[toxin]

They aren't making these hubs, they're from Nonplus
