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'

Is the max weight limit the same for normal version of rim, as well as also for light and super light version of rim?

120kg limit on T1100 SL version, 130kg limit on T800 QL version, no weight limit on T700 NL version

Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!
Quote from: SillyMochi on May 12, 2025, 07:32:27 AM
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.

hi sender, you who have experience with wheels, don't you think that 18 spokes per wheel are not enough to make the wheel rigid? I was thinking about wheels with 20 Peter spokes, but I'm held back by the idea that for a weight like mine, I'm well over 80kg, closer to 90kg, they are too delicate. can you give me your opinion? thanks

Hey! I know a bit about this  ;D but not as much as some! – for context, I was riding my CRW 50-60S wheels when I was around 90 kg and had zero issues. Those wheels have a max rider limit of 100 kg and run 16 spokes in the front and 20 in the rear, also  XMC  use T1100 in there higher end wheels which is more expensive that most of the the other OEMS I know use T1000 in there higher end wheels.
 
T1000 vs T1100 Carbon Fiber
Both T1000 and T1100 are high-grade carbon fibers made by Toray, a leading Japanese carbon fiber manufacturer. But T1100 is a step above in performance:

Tensile Strength:

T1000: ~6,370 MPa

T1100: ~7,000 MPa
→ That’s around 10% higher tensile strength.

What does that mean in practice?
With T1100, manufacturers can build wheels that are:

Stronger under stress (better for sprinting, cornering, and heavier riders)

Stiffer with less material

Lighter, since fewer layers or thinner layups can achieve the same strength

Stiffness Difference (10%+):
A wheel built with T1100 can be up to 10–15% stiffer compared to an equivalent wheel made with T1000, assuming similar layup and design. This can translate to:

Sharper power transfer (more efficient sprinting and climbing)

Better handling at speed

A more responsive ride feel

Of course, stiffness has to be balanced with comfort – too much can feel harsh – but T1100 gives designers more flexibility to fine-tune that balance without adding weight.

Toxin probably has a bit more experience than me on this topic, but wheel stiffness depends on a bunch of factors: rim depth, spoke count, spoke type, hub quality, lacing pattern, etc. It’s not always as simple as just counting spokes.

That said, going from 18 to 20 spokes likely won’t make a noticeable difference in stiffness. If you’re really concerned, you might as well go up to 24 spokes, at least in the rear. Stiffness tends to matter more in the back wheel, especially for heavier riders. So you could run 18 in the front and 20 or even 24 in the rear.

To put it in perspective, adding 6 carbon spokes only adds about 18.6 grams (carbon spokes are around 3.1 g each), which is basically nothing.

Also, deeper rims are naturally laterally stiffer than shallower ones, which helps even more with wheel rigidity. Rim depth plays a key role in stiffness too, especially lateral stiffness, so it’s another factor to keep in mind when looking at overall wheel feel.

In general, increasing spoke count and switching from steel to carbon spokes both increase wheel stiffness. Carbon spokes can add around 8–15% more stiffness compared to steel. Each step up in spoke count (e.g., from 18 to 20 or 20 to 24) can increase stiffness by roughly 5–8%, though the gains tend to taper off beyond 28 spokes. The goal is finding the right balance between stiffness, weight, and comfort depending on your riding style and terrain.

By the way, what rim depth are you considering? And what wheels are you currently riding – have you had any issues with them?
Personally, I wouldn't want super stiff wheels either – it has to be a balance. But finding that sweet spot can be tricky. Some riders know exactly what they like and stick to that format.

A 50/50 or 50/60 mm front/rear setup is a great all-round rim depth option – enough aero benefit without being too twitchy or overly stiff.

Re: Warning! My Experience with Winspace After-Sales
Quote from: peraal on September 03, 2025, 01:04:33 PM
This post is hilarious reading. 10/10 would watch the movie.

I second this...

OP, I'm making my first post just to point out how ridiculous this whole thing is. I agree with you that it is a bummer that something fairly simple, like a post collar was botched. Where I think this gets ridiculous is that you seemingly think that the moral high ground is worth the time, emotion, shipping logistics, making this post, among other things. Not to mention you probably initially purchased the frame with a "budget" in mind, albeit Winspace may be a premium brand in the east(china) it is still a budget brand in the west...

The collar from Winspace broke, after 2 years, even if you swear that you always use a torque wrench, no higher than 5nm, is the wrench calibrated? Do you think a collar on a mid range Specialized hybrid or $4500 Trek road bike (not ISM design) doesn't fail under similar conditions?  I'm guessing the collar was fatigued, bummer indeed but so is your attitude. Go buy something that's CNC'd from Wolftooth, Hope, i9 whatever from an LBS, they must have some hideous anodized collar for you. Please tell them this heartfelt tale of how you were wronged too by the way, I'm sure they will have a ton of sympathy. Maybe they'll give you one for free to get you to leave quicker.

Snide comments aside, as someone who spent 10+ years at a bikeshop and is now at a manufacturer, you seem like the sort of customer most folks come to dread. The validation you seem to be seeking here, is almost as insane as you demanding a company in China ships you a new seatpost collar.

Re: TanTan/Seraph TT-X69 - the 2026 edition
Quote from: patliean1 on October 29, 2025, 01:20:42 PM

Correct. It kind of rides like a Tarmac SL8 in terms of how it interacts with it's environment. Meaning crosswind stability and when at speed. It's literally the same shape and design. I said this in my video. Both frames are essentially identical in these specific regards.

That's pretty much where the similarities end for me personally now that I have several hundreds of miles in. It's nowhere as stiff and nimble as the real SL8. I've swapped in at least 3-4 different wheelsets, dialed in my bike fit, and put the bike through my usual daily workouts/efforts. I even swapped to a different cockpit. From the EXS Aerover (known not to be stiff) to Peter's XMCS's cockpit. How it interacts with the rider is a different experience than an SL8. So unfortunately that 20%-30% delta from a genuine Tarmac mostly all comes in its lack of comparable stiffness, nimbleness, and power transfer. It's more comfortable than an SL8 because it isn't as stiff. Nevermind about the fit and finish...

I've been purposely quiet in here about speaking on the X68. And TanTan as a whole. Trying not to be cryptic or passive aggressive. I'm not exactly happy with everything surrounding my dealings for the company. It's a story for another time. But I will at least say that the extreme variation in rider experience among several customers highlights that perhaps the build quality from TanTan on this particular frame offering is very inconsistent frame to frame.

It's rare that I feel worse about a frameset over time. The only frame I've felt this way about was, you guessed it, the TanTan X38 (Scott Foil clone). I cant figure out how TanTan can make such a BANGER for a GR201 gravel frame and be questionable at best in their road offerings.

Oh man. You should add this comment to your YouTube video. People watch it and think, wow, I'll buy an almost-tarmac for pennies! Personally, two people sent me this video. So, your opinion might push someone toward the disappointment you just described. Well, it's up to you of course, but what you wrote above is literally the opposite of what you talk about in the video, it's not "80% of SL8", but its "it looks like SL8 but nothing more". Peace.
