Tubeless experience? How do they run and setup tubeless?
I used 1 layer of Gorilla tape, AmClassic valves, and Conti MKII 2.4s that required a compressor but instantly seated on Flow rims. On the LB rims I had to remove the valve core to get the tires seated. Since then almost no leak-down and zero burping, so they work tubeless nearly as well as the best tubeless rims.

Just ordered two rims "wider stronger for DH race" from Nancy...that means 430-450g. In theory, carbon of this weight should be quite a bit stronger than the best aluminum... I think I'll lace them to Hopes and put them on my lighter 7" mini-DH bike to see how they run.

BTW: it is customary in China for people dealing with a lot of foreigners to take on a western first name for ease of doing business. Nancy most likely has a Chinese name as well.
Interested to know how they perform.

If anyone else has bought and used their DH 26 rims I would like to know a honest opinion. After reading much of these threads they seem like they could be solid

Looking forward to hearing more. What hubs and spokes?
Rear hub is a DT 440 150mm SS hub. I will be running 5 speed. Very wide flanges.
Front hub I thing will be a E13 LG1+ with very large flanges.

Your face.
Seems to me that running no-name carbon rims with the potential to explode on a hard impact (like say, oh I dunno, a rock) is like using a buck knife to get a fruit fly out of your eye. You might be successful. Might not.

Interested to know how they perform.


I'd be interested too. In the same way that I'd be interested watching a guy trying to headbutt a bus.

Are DH riders really that stupid that they'd risk a catastrophic failure of an essential part just to save a tiny bit of weight?

At times the stupidity of the cycling industry floors me, what with its ridiculous "standards" and such. Then things pop up and make me wonder if its just a clear reflection of the riders they service. Know what I mean?

This isn't really a DH rim*. It's their AM rim (normally 360g) with extra material added. They can do 385, 400, 430g versions. A wider DH rim is supposedly in the works.

*Yes, this is exactly what Enve calls a DH rim but that seems kind of hokey. Are we really to believe that despite the rest of the world extolling the virtues of wider rims the Syndicate guys asked for a DH rim that's like 22mm wide and just happens to have the same exterior dimensions as their AM rim? At least LB is honest in saying this is a beefed up AM rim and not a purpose built DH rim.

Ahhhhh I am curious as to how a product performs, me so stupid. 0_o Its clear from the 50+ pages of conversation on other forums etc, that many people have had a good experience with these and many have not. It appears to me though that more are having a good experience, and the ones that are not have had good customer service. I even see two riders in Isreal are running these rims on the dw DHR's and love them. Why don't you stop being a prick and shut the f*** up if you have nothing constructive to say?

Anyways, still interested in these. I think I will wait till the "dh" rim comes out and they change the manufacturing process on the 26" rims. When that happens I would be willing to give them a shot. I mean who in their right mind wouldn't be curious?

Me and my friend Dan, running this carbon rims tubless for a while now.
on our trail and on our downhill bikes.
here is a video we made.

http://www.pinkbike.com/video/298448/

so yes. it can be a DH rim.
you relly feel the different moving to carbon rims. the bike is more responding and light.
we are running 38psi back and 28 psi front.

Great video! Wicked bikes too.

Looks very promising. I would like to see them make something with the same profile as a DT Swiss F630, layed up to 450g. 500g would be nice, anything under that would be excellent. I would be a buyer. Hopefully they eventually come up with something similar.

The story is their engineers aren't working on a DH rim but one of their "customers" is and they will build it when the design is ready.

Interesting. Its a pretty bizarre situation. It seems as if their customers are basically doing the product testing and development. Not really the proper way to do business, but if they are refunding/replacing faulty products then I don't really see that much of an issue. Where else can the average consumer give their input and directly see changes? Pretty incredible. I imagine it could be done to a more successful and profitable degree if it were a domestic brand/manufacturer and had a better following etc. Any way, I will be trying to keep up with the happenings and may be a customer if they prove to have a decent product.

I think it is more like a company that offers carbon rims on their wheels (Giant, Speci, Syncros....) and gets them produced by them develops a DH rim. So not really an average consumer. ;)

Unlike SRAM who do no R&D and don't ask their customers what works. Maybe this way might actually work!

looks like it. later in the thread they sent him a new, updated carbon rim as a replacement.

it's not my cup of tea, personally, but he said he hit a jump and landed off camber or something.

Yeah, I know that guy. He's not slow, and he's not a featherweight either. I'm pretty willing to bet he has hundreds of pictures of bike components that have at one point exploded under him.

Looks like Industry 9 7000 series spokes. Must have been even stiffer with the carbon rim...

Yeah, being I9 spokes introduces some different variables. I've seen plenty of nipples pulled through a rim but 3 in a row is interesting. However the rim is very stiff, those spokes are very stiff, and I don't know how they're shaped and touch the rim compared to a normal nipple. Something had to give in a "kinda crash" landing. I can say with near certainty that a standard alloy nipple would have broken there. I've snapped a couple on hard impacts.

my only complaint about them is that the QR's that cam with them have some funky offset cam that requires them to be tightened more than normal qr's in order to actually be tight when they are shut. one of these days i'll dig out different qr's from the parts bin.

I think I found your problem.
