Re: Carbon spoke Q on new wheelset The 5.5 mm spokes don't fit the 20 spoke hubs, only the 21-24 spoke hub set. These are heavier, the spoke insertion and retention method is less reliable and potentially dangerous and the spoke count is just unnecessarily high. The 3.2 mm spokes that do fit the 20 spoke hubs are much worse aerodynamically. Shallower, thicker and a completely unoptimised cross section. The 5.5mm spoke also has fairly long cylindrical sections on the ends, worse than some alternatives.  This is another aerodynamic penalty.

Ornan could very easily get their hands on spokes that could remedy those critiques a little bit. They don't seem to be too keen on updating their site, maybe they do offer more on request.

I've run some cfd sims on these profiles, not enough to be conclusive, but I haven't been too impressed so far.

So in theory, when mold is pretty new, there is more wastage left on the rim? And the more time the mold is used, there will be less and less wastage? Does the same aplies also for the frames?
Does more waste influence the structure of carbon? Like in less stiff, more prone to fractures,...? Or is it only on the outside of surface?

Frame mold is totally different with rim mold, and the carbon fiber layups for frame is different with the layups for rim, but similar like that, new production frames on new frame molds would be a bit heavier. Anyway, the wastage rate of epoxy depends on several factors, new molds, different resin formulations, differnt molds materials, different carbon layups formulations, different factories production line operators etc.

We do the impact testing almost per 100 rims production to make sure the rims are still stiff and can pass 80J impact testing. And we need to maintain and polish the rim mold per 3 days, we need to prove the molds are still proper even per 1500-2000 rims production, if not, then we need to fix them. The structure of carbon on our rims wouldn't be influenced since we control the wastage rate under certain percent. But I am not sure about others'

Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!

Was thinking about starting a guide on how to get the best deals including different checkouts, coins, AE discount codes, store discounts, and events.

I actually made a complete guide a while back on reddit to get the best price when buying from AliExpress i will copy and paste it here.

Here is a guide fueled by years of experience as a buyer from AliExpress. I'll give you all the tips and tricks I know to get the best out of a product so that you won't feel like you got ripped off. You need to squeeze every few bucks you can from them.

Before I start, there are things you need to do:

Buy During Promotions: I encourage you to buy when there are promo codes available, if you have telegram you should follow This Channel which posts working coupons regularly. And send updates before evry new sale.

Add to Cart Early: If you eye a product and plan on buying it, put it in your cart 2 or 3 days before buying it. Keep an eye on your in-app DMs; most of the time, the store will send you a coupon to use for that product, typically $2 off $2 or $3 off $3. The message might be like: "Here is a coupon for items in your cart."

Check for Discounts and Coupons: When you find your product, scroll down a bit and check if there are "Discounts & Coupons." You will find store coupons there; take those. Otherwise, make sure to check the store's page, then go to the sale page (sometimes it's hidden, so make sure to hold the "New Arrivals" button then scroll left), or check the main page for any codes. Sometimes, just by following the store, they give you a $1 off $1 or $2 off $2 coupon. Follow them, get the coupon, then unfollow them to repeat this step for the next promotions lol.

Look for Coin Discounts: Preferably find a product that has a few percent off with coins; this is mainly displayed under the product's price in small text. Then you can use This Telegram Bot which will find a bumped-up coin discount for that product. If you don't have telegram, then you have to go to the coins discount page and look there for your product, most of the time it should appear there.

Know Basic Math: You might find yourself using a calculator from time to time.

Use Common Sense: I won't be explaining how to find a legit product in this guide, so make sure the product you are about to buy is not a scam using basic logic (checking reviews and the store rating, etc.).

Use the Mobile App: This guide is better used on the mobile app.

Now the practical Guide :

Let's say you found a product that costs $59. Add it to your cart. Most of the time, promo codes come like this: 3/29$, 8/69$, 20/169$, 30/239$, 50/369$. So the only code that will work in this situation is the $3/$29, right? Wrong! $59 is closer to $69 than to $29, so we can squeeze some bucks out for our product. Let's do it in the most perfect way, down to $0.1.

Calculations and Preparation :

We'll start with some calculations. Assume you found a product with coins discount, passed it through the bot, have store coupons, and collected AliExpress red coupon codes automatically. There's also a $1.99 shipping fee. Click on "Buy Now" or "Checkout" in your cart (DON’T CLICK ON PAY NOW), just check out the final price. Let's say we found discounts like this:

$4.14 off from coins

$3 off $29 from AliExpress coupon/codes

$2 off from a store coupon

$1.99 shipping fee

The final price will be: ($59 - $4.14 - $3 - $2 + $1.99) = $51.85

Remove the $3 red AliExpress promo code from the equation because we will be replacing it with $8 soon. Also, remove the $1.99 shipping fee, as AliExpress promo codes don’t include that in the final price. This means you actually need a total of $70.99 for the $8 off $69 coupon to work! So, our product price becomes: ($59 - $4.14 - $2) = $52.86 As we are eyeing to use the $8 off $69 code, we will do this simple math: ($69 - $52.86) = $16.14. This is the price difference we need to be able to use the $8/$69 off.

Next, go to the homepage, search for a generic term like “metal” or “plastic” as these words give a big list of products to choose from. Then, on the top right, click on the 3 lines (the filter button), click on "Free Shipping," and in the minimum price, write $16.14. For the maximum, add $0.1 to the price, making it $16.24. Click on "Show Results." If there are 0 products in your price range, increment the maximum price by another $0.1. Make sure to look for a product that doesn’t have any coin’s discounts (you will find “Price shown before tax” alone without “Extra % off with coins”). After you've done this, add it to your cart.

Go to your cart, select both products, and apply the $8 code. It should work now! But there is a catch. In reality, you won't be getting $8 off your main product but on both products. With more math, we can guess how much your product will save.

$8 off $69 X off $52.86 X = ($52.86 * $8) / $69 X = $6.13

This is the new AliExpress red coupon that your product will get out of the $8, which is $3.13 more saved overall compared to the initial saving. The other product will get the rest, $1.87.

Next, we need to get rid of that extra product because we don't need it.

2. Freeze Payment Method/Buy then cancel :

Warning: Before the next step, freeze your credit card or move your funds out of your card to your account if you don't want to wait for a refund. We want to make a failed payment to be able to get rid of the $16 product added at the end. After freezing your card, select both products, apply the new code, and attempt the payment. The payment will fail because you don't have any funds, or your card is frozen.

3. Cancel Extra Product :

Go to the account page, check "My Orders," and then click on "To Pay." You will find two failed payment products. Cancel and remove the extra product that you don't want.

4. Finalize Payment :

Unfreeze your card or move funds back to your card, then pay for your product. The calculation will now be: $59 − $4.14 − $6.13 − $2 + $1.99 = $48.72. Initially, it was $51.85, so it’s an honest save.

5. Repeat and profit.

These steps may seem tedious when you read this long text, but believe me, once you get the hang of it, it won't take you more than 5 minutes to do all this.
