1000 Gram Chinese wheels

Notices
Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

1000 Gram Chinese wheels

Hello, a long time ago I wanted a light carbon wheelset.My budget was strict, less than 450 euro, so the only wheels I could get were chinese ones.
The 50mm profile seemed too deep for my 58 kilos.I wanted something between 30-38mm.I had found some on Ebay, about 1150 grams 38mm profile.
They seemed fine, there were a couple of reviews too.However, I searched up in case I found a lighter wheelset, with smaller profile.A 25mm one would
be fine, but I wanted them to be a bit more aero, something like the 35mm Dura Ace ones.

I started searching up on Alibaba, and found a pretty decent and reasonably priced (For what it offered) wheelset.It was more expensive than the ones on Ebay.
I just searched light carbon wheelset and found them.I contacted Betty immediately on skype, (Their sales manager I guess?) since their light wheelset (1000grams) had 32mm deep rim profile with foam core rim made using Toray T1000 M40 And T700, which seemed ideal for me.I was still skeptical about buying from them since I hadn't found any reviews on forums, even if there were, they would be on a huge chinese thread (On other forums) which I wasn't able to spot even once.I had only found once on another forum but I never found that post again.

The support was great so far, Betty answered all my questions, we were talking for about an hour, even regarding technical issues.She was also online whenever I had a question I was provided many photos of their products on the spot, the built wheelset with other hubs and options and so on.

Furthermore, I was also provided with a titanium QR set, 2 valve extenders, 2 sets of brake pads (1 set=2 pads) a double-sided wheelbag and two spare spokes which I even didn't ask/pay for.Betty asked me to confirm the order and my details to make sure everything would be fine.I paid through paypal, I received photos of the wheels and parcel before shipping it to EMS and later I was given the tracking number.They informed me that the wheels would arrive in Greece in 9 days.And they were right, the wheelset arrived in exactly 9 days in Greece, including EMS' delay and the amount of time which was needed to be send to EMS.

The wheelset was nicely packed, the box was too thick and they weren't damaged during shipping.They look nicely made, the UD surface is very nice so is the braking surface.The tension seems the same in between all spokes, except the drivetrain's side where the tension is higher.I also weighed them to make sure they were around 1000 grams.So far everything seems perfect, I can't wait to test them, I will be probably putting Tufo S33 or S22 Tubular tires on them.Also, is 25g of glue enough for both tires?
Ι forgot to mention that I ordered these wheels with Bitex hubs( The set which is 257g can't remember its name ) and Dt Swiss Revolution 2.0 - 1.5 - 2.0 spokes.Price was 434 Euro, I didn't pay any import taxes either.

Here are some photos too.

No. At a minimum you need 3 thin coats of glue for each wheel. (one on rim, one on tire, allow to dry, and third coat on rim to mount.)

http://cnl.salk.edu/~jorge/xfer/Tubu...icePart1-4.pdf

You won't get 6 coats of glue out of a 25g tube.

Yeah, there are 9000+ different "standards" for gluing a tubular. I put one coat on the wheel (not too thin), one coat on the tire, let them both dry overnite. Spray the wheel w/ water before mounting and then put the tire on, make sure it's centered and then pump up to about 120-130 psi and let it sit for at least 3 hours (the longer the better).

I know, it's wrong and I'm going to roll a tire and regret it one day--- 10 frikin' years and I'm still waiting to roll a tire.

Other than a bit of mess, why don't you put a third coat of glue on before mounting instead of spraying it with water?

That would bring your process more in line with what most folks do, and doesn't seem to have much downside.

I'm surprised you say that the spokes are DT Revolution 1.8/1.5/1.8 type. I have bought many of these, but thought were discontinued. I only see them on closeout in the USA and then only rarely. They are definitely not as durable as the current 2.0/1.5/2.0 variety since it is at the ends that breakage commonly occurs. Perhaps the vendor misspoke and you have the slightly heavier/stronger spokes. That would be desirable.

Yes you are right, I couldn't remember what kind of they were, I was too bored to search it up anyway.They are 2.0 - 1.5 -2.0 as you said.I checked it right now.

Excellent.

BTW, Bitex hubs are very good value for the money. Built with quality bearings and very light weight. In the US we use a lot of them for ultra light and inexpensive wheel builds. I think you will be very pleased with them.

Please report back when the foam core acts like a heat sink and the rim melts. This technology was abandoned a few years ago for this very reason.

Why would it melt...Do you have actual facts that this happens?
Edit:So Zipp, Corima and Lightweight are stupid to have foam core rims right?

Yes. Go to the RBR site and see for youself. This is a HUGE thread on Chinese carbon. There are several posts in there about these rims asploding.

The aboved mentioned manufactureres use more expensive HTg materials. Cheap assed Chinese carbon ain't that.

They get asploded because they are Clincher rims, you haven't tested these to judge.Because I haven't seen a single post about a foam core rim there.And just for your information, a manufacturer-shop is selling wheels with their rims.I won't waste my time with you.Begone.

Yes. I have tested these rims. Twice. They asploded real good.

Read the thread again. There are several posts on Chinese foam core rims failing.

You really think they are a manufacturer?

Alibaba verifies that their capital is 500,000RMB. That's about 80,000US making them a trading company NOT a factory.

From Alibaba:

"Business license:
Registration No.: 350206200061478
Date of Issue: 2008-04-25
Date of Expiry: 2028-04-24
Registered Capital: RMB 500,000

I didn't say that the manufacture them, I doubt it that anyone on Alibaba's chinese components are made by them.And about that "Yes. I have tested these rims. Twice. They asploded real good." Pics or it didn't happen.And arc carbonwheels uses these rims.

they lost me at that ridiculous photoshopped "customer photo" and the fact that you have to pay return shipping for warranty work.

Yeah I've noticed that photo too, sucks a bit.About the warranty thingy, they at least offer 18 months and not 12.Unfortunately 90% in every Chinese seller, you pay the shipping back.(According to what I've read in RoadBikeForums.)

I imagine if it acted like a heat sink, it would help, no? Perhaps the issue is that it serves to insulate and increase heat retention in the brake track area?

I've build a couple of wheelsets with Bitex hubs and they have been faultless so far; free spinning, no wobble, no breakage or other issues. I'd happily spend more on hubs if I was convinced they'd be better in some useful way.

Sure, I'll just forward our entire R&D hardrive to you. Please send me your ship to...

So I guess you didn't scroll through the RBR link I provided? Honestly, I don't recall where those posts pop up so it would be a bit of work but they are there.

I didn't say they are manufacturers, I said about a company selling wheelsets using their rims, but it seems that your mental abllity is not that high to understand some simple phrases.

I doubt it that they have ultralight clinchers.I do not recommend clincher anyway, the sidewalls tend to overheat.

He means they sink heat into the interior of the wheel, not to the air. Then that heat is trapped really well since carbon is a pretty decent insulator and the heat can't radiate back out well.

It would help for a short time, but when the foam got hot...
