Author Topic: BladeX: 15 Years of Carbon Wheel Manufacturing, Now Building Wheels for Riders  (Read 18644 times)

Thanks for your detailed feedback, Stephen — this is actually where I first came across it.

I guess this is exactly the value of real-world testing by end riders. Even though we do lab tests — impact tests, fatigue testing, stiffness measurements — how a wheel actually feels on the road is just as important. Plus, real riding often surfaces issues we missed, or new ones we hadn't considered.

Before we deliver the final products, all of this feedback helps make them more reliable. Either way, we'll always stand behind our products and take responsibility when something goes wrong.

Let's address what happened with the bearings. First off, like most wheel makers, we don't manufacture our own hubs — that's a completely different engineering specialization.

Initially, the hubsets were designed with steel bearings, which worked great. However, there's always market demand for ceramic options, so I wanted to run some tests to see how they'd perform. I asked our supplier to make samples using TPI ceramic bearings, specifically requesting TPI because they have a great track record in DT Swiss hubs.

We built and tested those wheels, and initially they felt solid. But when Stephen received his test wheelset, he noticed some play in the hubs. I immediately suspected a bearing tolerance issue, something I've actually run into a couple of times with newly launched DT Swiss 240 EXP hubs in the past. When I pressed the supplier, they admitted the entire batch of TPI bearings they received had the same defect.

Looking back, it boils down to two problems:

1, that specific batch of TPI bearings had quality/tolerance defects.
2, the supplier installed the wrong bearings in that batch without flagging it themselves.

Stuff like this happens during new product development. That's exactly why I wanted to share this process openly, most end-users only ever see the polished final product, but the messy trial-and-error behind the scenes is where the real engineering happens.

It was around 2mm of movement at the rim, so we’re not talking about the wheel moving around massively.

The way I noticed it was once the wheels were fully mounted on the bike. I always grab the top of the wheel and physically rock it from side to side to check for any play. That’s when I could feel it.

If the wheel was simply mounted in a truing stand and spun to check radial/lateral true, I honestly don’t know whether you’d notice it. Even when moving the wheel around off the bike, the play wasn’t particularly obvious unless you were specifically looking for it.

I’m also not sure how reasonable it would be to expect a wheel builder to check that their hub supplier had fitted a bearing with the wrong internal diameter by 1mm. The explanation I was subsequently given was that a 14mm ID bearing had been fitted where the hub required a 15mm ID bearing.

Once the correct bearings were fitted, the play disappeared and the wheels remained true, so thankfully it was a relatively straightforward fix.

Obviously, if I’d purchased the wheels myself I’d have approached it in much the same way. A problem isn’t ideal, but if the company identifies it, supplies the correct parts and covers the cost of putting it right, I’m personally fairly reasonable about these things. Jason had also made it clear that if the bearings didn’t resolve it, the wheels would have needed to go back.

Thankfully that wasn’t necessary and the replacement bearings solved it.

the ai slop is not helping convince me to buy your products

Just resist the urge to send this sh*t, please. respect us.

so 18mm and 21 mm inner width in 2026 that is a bold choice, and 25mm as does everybody else, cheaper. And the same crappy OEM hubs as everybody else, good luck

I'm gonna interject here the AI comment is a bit small-minded to be honest.

I've spoken with Jason quite a lot and English clearly isn't his first language! he is Chinese ffs . He's a Chinese manufacturer trying to communicate with an English-speaking audience, so if he uses AI to help translate or structure his posts I don't really see the problem myself. AI does not write for you. You have to feed the information in and it essentially re writes the reply.                             

I'd rather a company communicate openly and explain what's happening than stay silent. The important thing is whether they're honest, respond to problems and stand behind their products when something goes wrong.

And for the second comment:

The comment about inner widths and hubs is equally strange to me.

Pretty much every wheel brand uses OEM hubs and rims in one form or another. Very few companies actually manufacture their own hubs from the ground up, including a lot of premium brands.

As for internal width, not everyone wants a 25mm internal rim. Different riders, tyres and use cases suit different designs. An 18mm or 21mm internal rim isn't automatically bad just because wider rims are popular at the moment.

Ultimately the things that matter are rim quality, build quality, reliability and after-sales support. That's what separates a good wheelset from a bad one, not whether the hub started life with an OEM manufacturer.

Of course, but sourcing an appealing, reliable product lineup is exactly the brand's core job: that's where they earn their margin. Saying "everyone uses OEM" is not a free pass; the question is which OEM parts they pick and how they vet them.

Rim quality: fine, most rims are decent these days.
Build quality: sample size of 1 on this forum = 100% failure rate. That bearing mismatch was a basic error.
After-sales support: Not a single C1-C2 speaker?
Reliability: still unknown.

You admit you've spoken with Jason a lot and got FedEx spares overnight at no cost. That's not how every retail customer can get treated.
So genuine question: are you defending the wheels as being good enough, or are you defending the VIP experience you received?

Ahh, no surprise, this is exactly the kind of reply I was expecting from my forum post 😂

The OEM point isn't really what I was defending. I'm not saying it's a free pass at all. My point was simply that the vast majority of the industry works this way. That's just a fact. The important part is which suppliers are chosen, the quality control, the build quality and the support behind the product.

My original comment was mainly in response to the AI criticism. I've spoken with Jason quite a lot and English clearly isn't his first language. He's a Chinese manufacturer trying to communicate with an English-speaking audience. If AI helps him translate or structure a response, I honestly don't see that as a major issue. I'd rather a company communicate openly than stay silent.

As for the treatment I received, obviously I can't guarantee every customer would get exactly the same experience, but I would however expect them same as a paying customer . But speaking to the man, I'd like to think they would. The bearings were supplied because there was a genuine issue to resolve and the alternative was returning the wheels. From my conversations with him, I don't get the impression they're only interested in helping reviewers or forum members.

There are many good products on the market today, and to be honest I've had very few issues with any of the wheelsets I've owned in recent years, whether they were supplied for review or purchased with my own money. The whole "free wheelset" thing is actually quite new for me. The vast majority of wheels I've ridden over the years were bought and paid for by myself.

I'm also under no obligation to say anything positive. I don't get paid for this. Yes, some companies have supplied wheelsets, but nobody is paying for the tyres, discs, cassettes,  and all the other bits that I have to buy myself to actually build, ride and test them properly that includes the time spent.

Any company that has supplied me with wheels, I've spoken to directly and done what I consider reasonable due diligence before forming an opinion. That includes asking questions, discussing specifications, looking at previous customer feedback and understanding how they handle after-sales support. But due diligence only goes so far.


I'm not here defending BladeX as the greatest wheel company on earth. I've got a sample size of one wheelset and I've been open about both the good and the bad. The bearing issue happened, I reported it, they addressed it, and the fix worked.

If a product is poor, I'll say it's poor. If there's an issue, I'll report it. That's exactly what happened here. I didn't hide it or gloss over it.

Ultimately, you can take what I say at face value or not, that's entirely up to you. I honestly couldn't care either way. I'm simply sharing my own experiences and opinions based on the products I've used. I'm not trying to convince anyone to buy anything, and I'm certainly not here to act as a company's marketing department. Time and real-world use will tell the true story.

I appreciate the honest reply. I'm not questioning your integrity, I'm questioning whether your experience is representative.

And let's be honest, it's a delicate topic. We are all scouring forums in order to get the best unbiased information.

That’s a fair distinction, and I understand why you’re questioning whether my experience is representative of an ordinary paying customer.

The honest answer is that I cannot prove every customer would receive exactly the same treatment. I can only report what happened in my case: there was an issue, I raised it, replacement bearings were sent, and the problem was resolved. I would certainly expect a paying customer to receive at least the same support. It would be completely backwards if somebody spending their own money were treated worse, but until other customers report their experiences, neither of us can know that for certain.

I also completely understand why people approach reviews of supplied products with some scepticism. That is reasonable. However, receiving a wheelset doesn’t automatically buy a positive opinion from me. I’m not paid for my time, and properly using these products still costs me money. Recently, I’ve bought four sets of tyres and three sets of discs for different wheelsets. I also have a full-time job, a family and a life outside cycling.

Realistically, very few people could afford to buy ten different wheelsets purely to review them. Companies supplying samples is therefore a necessary part of how lesser-known products get tested. Many of the same people who criticise reviewers for accepting samples also understandably won’t risk buying an unknown product until somebody else has ridden and reviewed it.

I’ve been buying Chinese wheels with my own money since 2019, beginning with the original rim-brake Winspace Hyper 50 after owning Zipp 303s. Since then, I’ve bought wheels from Winspace, CRW, XM Carbon Speed and various smaller manufacturers. Receiving review samples is relatively new for me, and I still judge each product by what I actually experience.

Most modern carbon wheels are fundamentally pretty good. The real distinction often becomes quality control, specification and, most importantly, what happens when something goes wrong. No warranty is completely ironclad, whether the product comes from a small Chinese manufacturer or a major established brand. The larger brand may provide more confidence, but customers still sometimes have claims refused or handled badly.

Regarding my original comment, I wasn’t really defending BladeX or promoting its wheels. I was defending Jason against what I thought was an unnecessarily dismissive comment. He is Chinese and English isn’t his first language. If he uses AI to translate his thoughts or structure them for an English-speaking forum, I don’t see anything inherently disrespectful about that. The substance of what he says can still be questioned without attacking the tool he used to communicate it.

For complete transparency, I use AI myself. I dictated the substance of this reply into it because I simply don’t have time to sit in front of a laptop typing long responses. I use AI in my everyday life and at work, and I’ve used it for several years. I’ll dictate or draft what I want to say, use AI to improve the structure, spelling and grammar, then read it through and change anything I’m unhappy with before posting it.

They are still my thoughts, experiences and words; the tool simply helps me present them more clearly and saves me time. I see absolutely nothing wrong with that. If somebody objects to the use of AI on principle, that is their issue, but using it does not automatically make the information dishonest, meaningless or “AI slop.”

You’re entirely entitled to question whether I’m biased, and you’re welcome to message me privately if you ever want to discuss any of this. All I can do is disclose how I obtained a product, report the good and bad honestly, and let people make up their own minds. In this instance, the wheels developed an issue, I reported it publicly, BladeX addressed it, and the solution worked. That is the experience I can genuinely report; time and wider customer feedback will establish whether it is representative.

Hi everyone,

I'd like to share some updates regarding hub supplier evaluation for future BladeX wheels, and ask for your real‑world feedback.

I've been disconnected from the end market for years because I've been focused on OEM work. I'm eager to reconnect with the end‑user community, so any suggestions you may have are very welcome. All input will be taken into serious consideration.

Over the years we have worked with DT Swiss and Taiwan‑based hub manufacturers, and we rarely ran into hub‑related problems. But following the earlier bearing‑related issues we encountered, I've been reassessing our hub suppliers.

This experience has made me realize how critical supplier reliability really is. Quality control matters as much as hub design itself.

So we need to be extremely careful when selecting our next hub partner. My current preference is to work with OEM factories that already have large‑volume real‑world deployments and proven reliability.

H‑Works seems to has a strong reputation among riders, and their facility is geographically close to us. So I reached out to Carol and arranged a factory visit.

Here are several things I would like to share from my visit:

1. H-works have a full range of CNC machinery and testing machines. They also have wheel road‑test machines to test hub performance when built into wheels.

2. Carol explained their internal production approach for bearings: they machine dedicated hub bodies and control the bearing seats matched to the exact specification of ceramic or steel bearings they use for each build.

3. On the topic of titanium hubs, which some riders are curious about: Carol told me they have produced Ti hub samples in the past, though there are notable drawbacks:
- CNC machining speed is very low; one machine can only produce around 10 pieces per day.
- Titanium swarf created during CNC machining can present a fire risk, so the machining process requires careful monitoring, something I had not anticipated.

4. For their sub-220g ultra-light hubs, they are keeping production tightly constrained and actively gathering real-world rider feedback before wider release.

I also toured another pure play OEM factory that supplies hubs for Elitewheels. This manufacturer does not sell direct to consumers, so it is not widely known within enthusiast circles.

I would love to hear your real‑world experience:

- Has anyone here used H‑Works hubs long‑term?
- How has reliability been?
- Has anyone used the carbon‑spoke hubs from Elitewheels?
- Are there other Chinese OEM hub manufacturers you would recommend I evaluate?

Thanks for sharing your thoughts.

Have you checked THRIndustries? Their R2 hubs is actually good. I have them on my wheelset atm from DFS and it's pretty solid

Hi, thanks for sharing! I'm not familiar with this name, and I googled it, it looks like they're based in Taiwan?

I have contacted the person from THR hubs. Their hubs look great in appearance and have a high quality feel, with an appearance similar to Chris King. Can I ask how many km it has been ridden on your bike?
