Hi all! I would like to ask you if you can suggest me a light carbon clincher/tubeless disc rim; I want to build a wheelset around or under 1300g for my road climbing bike... Ps: not hookless ;-)
Thanks a lot!
Clincher carbon rims don't get much lighter than alloy. They are much stiffer and allows your wheel to stay true better.

Tubeless, disc brake make wheels a bit heavier. (No brake track will often help weightwise.)

You will be pressed to make a cheep disc brake wheelset at 1300gr.

What's your budget? What do you weigh? How low pressures do you like to run? Are you a sprinter?
Thanks a lot alcatraz!

I would prefer carbon rims for an higher profile than alloy (not so high, but around 30-40mm) and for their stifness, as you said.

My budget is around 1000$, but less is always better ;-)

I'm 60-61kg and I'm a climber, sprints are not my job! I usually ride with clinchers (not tubeless, which I never tried seriously) around 7bar; my rides are usually very hilly.

Thanks a lot in advance for your suggestion! And sorry for my poor english :)

Can't go wrong with 38mm for a climbing/allround bike. It'll give you a bit of free speed on flats/descents while not adding more than around 50 gr over the shallowest rims.

7 bar and 60kg you don't need any crazy wide rim. 25-28mm wide is sufficient. 23mm tire being optimal aerowise, 25mm being acceptable' like on the rear wheel. Might even be wise from a rolling resistance point of view.

As for hubs there is a debate on what is a good choice right now. Some people get pissed when the hub needs servicing 1-2 year intervals, and some would gladly take the weight reduction.

I live in China so I'm not familiar with the hubs available to you. Are you going to build the wheel yourself or let someone do it? A builder that guarantees the build would have certain hubs/spokes in mind.

I'm an amateur that builds his own wheels. If I were you I'd pick 24 spoke rears and fronts. Check farsports for rims maybe. Depending on the hubs you should come out to 1350-1450gr. Spokes that are in that price range would be aero ones like sapim cx-ray's, cn424, pillar1420. Spoke nipples I recommend alloy Pillar DSN. As for spoke length calculation it depends on your hub/nipple choice.

Thanks for all the suggestions!

I've got a "pro" wheelbuilder friend, so he will assembly for me the set.

Usually I ride with 25mm clinchers, so a 25mm rim widht I think could be ok. For the hubs I was interested in the newmen or carbon-ti set, they are light and look "serious".

I was also looking these rims:.

What do you think about the 25mm width version? Clincher/Tubeless and 25mm or 35mm depth

They look very nice. With a slightly narrower internal width they may allow a true 28mm to work on the front. They say tubeless only. I assume it's still fine to run tubes.

Have you found any reports on them?
Only the same things emotive posted above, but they also offer a symmetric rim with those dimensions anyways
Hmm. I suppose a quick message to Yishun to address the spoke drilling could help. However, it really sounds like LB are reliable. How much better do you think Yishun's profile is over LB's? Does asymmetric matter at 56mm. At that depth (56mm), does the U shape still trump the hybrid shape LB has?
I asked hambini via email his opinion on the profile and he suggested depth trumps all. He said the yishuns would probably rate about the same as the dura ace c60/50 which are basically the same as the LB rims. I got a quote from yishun - they were cheaper than LB but heavier, I'm not ready to pull the trigger yet.

If you do please post back with your opinion!

On the back of that info I'm probably going to pick up 3 RR56C02s. A 24 hole front disc for my next road bike and 2 x 28 holes for a son28 12mm CL front and disc rear.

I'm sure you'll be happy. Could always just ask yishun for a quote as well.

Hasn’t arrived yet, but what depth do you guys think I should get to go with this frame? 46/56mm?

I'd go with LB 56. Does the fork has massive clearance like other aero disc forks?

Regarding carbonfan.com. Anybody ordered from there?

I bought the three rims last night. I’m going to purchase the hardware from BHS and will build them up in the near future. I’ll post some pictures when they’re done.

I'll let you know what it gets here. I'd hope so. I'd like to be able to run a big fat 28mm tire on it, front and rear.

Also hoping/guessing the fork has partially internal cable routing. Hard to tell from some pictures.

Edit: After looking at a couple other resellers of that frame, it looks like the fork has internal routing coming in from top of the left fork leg.

Are LB the best deal going these days for wide, moderately deep carbon?

Hard to keep track of all of the companies. Nextie seem to be $20-30/rim more expensive, and slightly heavier, for a comparable product.

Does anyone know if any manufacturers make a 650b disc wheelset in the sub $500 range? The lightest thing I can find are hunts wheels at about 1550g

Is there a source of pre-built wheels that seems to be reliable and well made, or do you have to buy the rims then have someone build them for them to be trustworthy? Looks like alibaba is having a big 11/11 sale and there are lots of wheels there, who knows if they are good or not.
