Re: Yuanan Carbon fiber wheelsets Year end discount promotion @Leon
I often think about the quote I was given 2 years ago for 2 wheelsets but I was quoted 160usd shipping for 2 cartons, is there a way you could combine shipping in the same box? I'm willing to wait longer if it means lower shipping cost

Additionally, when is typically the biggest sale of the year for yuanan? Is there a discount on all products or only a select few

Hello dear friends, have a nice day! As the carbon wheelsets market continues to evolve, our factory is ready to start building a new batch of carbon wheelset molds. What is your Dream carbon wheelset? Please give your suggestions generously, including carbon wheelset type, inner and outer width, weight requirements, spokes and hubs, etc. Effective and practical suggestions will be adopted and surprise gifts will be given to you! Please actively participate! Thank you very much for your suggestions!

Integration of the dual ratchet system in lower end wheelsets would be lovely.  :)

Re: Yuanan Carbon fiber wheelsets Year end discount promotion Perfect, love talking about rim design.

My ideal wheelset:

Let start with the general shape of the rim profiles. Elilptical like the scope rims in the attachment. This is critical in the front rim. This profile provides a great balance of speed and stability and is used by dt swiss/swiss side who make very fast wheels as well as specialised on their very fast roval rapide clx II, though scope claim theirs are even faster. The idea is that the cross section of the tire and rim combined forms an ellipse. It works well both when the airflow hits it for the first time and the tire is the leading edge and rim the trailing edge and when it hits it a second time when the rim is the leading edge and the tire the trailing edge. A V shape does the first well, but absolutelly terrible at the second.

Hubs and spokes:
Obviously deep aero carbon spokes. The hub interface should be something similar to farsports, scope, crw, etc. Basically replicating a regular straight pull hub but with carbon spokes. This is safer because the spokes wont pop out in case of rapid tension loss, lighter and smaller so more aero. H-works make great hubs like these and aparently dt swiss are moving into this area as well. The spoke to rim interface should have an external nipple like the new superteam wheels, so its possible to true the wheel from the outside with a mounted tire. This makes servicing easier and allows you to true more accurately. It also means you don't need spoke access holes in the rim bed so no need for rim tape. Ideally you would have as much of the nipple still hidden, showing just enough to be able to work on them.

Front wheel:
50-55 mm deep, from the development white papers I've seen, 50 mm is around when a wheel can start taking advantage of the sailing effect at higher yaws. 21-22 mm internal width and 30-31 mm external width at the rim edge. That way you can put 25 or 28c tires on without them balooning beyond their labeled size and they will stay narrower than the rim giving the best chance to form the aforementioned ellipse.  As low a spoke count as is feasible to reduce weight and improve aerodynamics. Stiffness isn't as critical in the front as it is in the back.

Rear wheel:
60-70 mm deep, 24mm internal width and 34-35 mm external width. This one is way wider because the air is so messed up by the time it gets to the rear tire that width matters a lot less for aerodynamics as their biggest impact is when providing a sailing thrust effect in crosswinds. Therefore we can mount a wider tire for improved comfort, rolling resistance and puncture protection. Elliptical shape is probably still ideal but less critical as the first time air will hit the tire is at the seat tube where airflow is all kinds of messed up, so optimising the design for when the air hits it the second time could be more beneficial. Tire should still be notably narrower than the rim. Spoke count should be higher, probably 20-24 spokes. Ratchet hubs with dt swiss compatible internals.

Obviously everything should be as light as possible :D

Edit: also no wavy rims, their only benefit is better cross wind stability by reducing the stall angle of the wheel i.e. the airflow is so messed up that it doesn't even push the rim anymore, meaning you lose the sailing effect. This is unneccessay with good eliptical profiles because they can enable the flow to have a smooth transition from one side to the other.

Re: Yuanan Carbon fiber wheelsets Year end discount promotion i would say 32mm wide, 50mm deep. Or even 34mm wide. I guess a vote on the forum could be useful.
I think 50mm is deep enough without being too deep for most guys in most situations. If you sell a lot to women & small riders, then maybe a shallower version too.
if 32mm wide, 30C tyre is probably idea, but you can probably be fine with both a 28C as well as 32C.
If 34mm wide, you can put 30 or 32C and should have a perfect tyre to rim transition.
I think steel bearings are fine because to my best knowledge, ceramic bearings for cycling applications make no sense.
No wavy rims.

Re: Yuanan Carbon fiber wheelsets Year end discount promotion We want hooked rims! Hookless is a terrible trend. I agree about rim width - 34mm is pretty good for 30-32mm tires. 60-70mm deep is fine. Lots of shallow rims in the market - don't make another one!

First of all props to you Leon for doing a market benchmark. Means you are smart and also doing it by feeling through what people say is what people do.

My 2 cents are the following. 1 improve your website, 2 have some fully prebuilt options rather than leaving everything for the end user (most won't understand much than
a) how they look,
b) how much they weight
c) how much they cost
d) how deep they are

Yes, you'll always have people who want fully custom bla bla bla. That's about creating and developing a super nice wheel online configurator. Much better that lightbycicle. Text me if you need help on this.

Anyway market seems to follow the trend:
1- Wavy and non wavy wheels
2- Light. Weight matters
3- Different carbon layups
4- Medium low noise hubs
5- Larger outter width. Minimum most people use nowadays is 28, and most are shifting to 30 and 32 - the larger the frame allows. Internal width minimum 21.
6- Rim brakes u probably know best the market but not sure it's worth any development in that direction.
7- Stiffness/spokes confort vs Stiffness vs maintenance
8- Dropshipping/warehouse inside the EU for faster delivery and receiving.
9- wheels for ebikes with some bits and bytes

This is a mix between business advice and wheel but I think u get the point. This industry is not so focused on this. Opportunity is not in the wheels itself;)
