Xiamen Carbon Speed rims/wheels

[Paddy2Fast4u]

I‘ve been riding
D50CU-31 T1100 rims 20/20H UD matt
Black colour in-house hubs 20/20H 54T sprockets TPI ceramic bearings centre lock straight pull for 100*12/142*12 with Shimano HG Driver
5.0mm carbon spokes
since mid/end of June.

Now they're starting to make noises. A quiet creaking noise when I pedal. After checking the crank and bottom bracket twice, and two different chains and cassettes, I've ruled out the Shimano drivetrain. Today I fitted a different rear wheel and I couldn't hear it anymore. I've taken the freehub off the rear wheel and, when cleaning the components, I noticed metal shavings. It was on my cleaning Paper and Fingers. You can also see wear on the pinion gears. I haven't disassembled the freehub any further as I don't have any tools at hand.

I'm surprised to notice this after such a short time. I wrote to XmCarbonspeed Right now. I am excited how they react.

Thanks for youfeedback and sorry if I didn't reply your email in time 5 hours ago, time difference anyway. I think I'd better reply here directly, others can see how we deal with this as well.

If the roads there are dusty not very good, even you ride with original DT Swiss hubs, you need to do proper maintenance after decent miles as well.
Please clean the rachets and use new grease, if the noise is still there, we can send you new rachets, even new axle and bearings if you think needed, as soon as you could confirm what the exact problem is, we would handle that for sure.

And we will upgrade the rachets with titanium material to make them with better performance, we are testing them now.

Thanks for the quick reply. I got to work on it over the weekend. I thoroughly cleaned the pinions with brake cleaner and regreased them. After a longer test ride, I can say that the freewheel was definitely the cause of the cracking. I'm wondering how long the cracking will stop. If it only lasts 1500km, as before,I'd have to repeat this cleaning procedure every 2-3 months. Since there was already considerable wear on the pinions, I suspect the wear will continue. I hope you can see in the pictures how small metal parts are missing from the surface of the pinions.

Can't wait to see what the 16 spoke with 5mm spokes will look like. I think they'll look amazeballs!

Hambini (yeah, I know) just posted a set on his Facebook page. Allegedly going to the wind tunnel. https://www.facebook.com/reel/780023861527634/

Just confirmed a DT Swiss 350 freehub will fit into XMCS Hubs

[peterpanpeter]

So they offer three different hubs: 20/20, 18/18 and now a 16/16? Is there difference in the ride feel besides the weight? Does the rim flex more with less spokes? Is price the same for all hubs?

21/21, 20/20, 18/18, and single front 16H hub option, no 16H option for rear wheel.

And only 21/21H hubs wheels on promotion with discount, 20/18/16 hubs wheels won't be discounted this year due to the effrot and money on these new development hubs, and they are obviously not same price.

Is the XMC 36 ratchet hub identical in construction <-> dimensions to the DT Swiss 350 with 24 holes?

Peter is releasing a set of titanium spoked wheels...

-CarbonSpeed CS56 Pro - More on this "pro" line of wheels at a later time.
-50mm / 31mm ext T1100 rim 24mm internal
-60mm / 31mm ext T1100 rim 24mm internal
-Titanium spokes with Sapim self-securing aluminum nipples
-New version in-house hubs 24/24H
-54T ratchet
-TPI ceramic bearings
-Weight 1250g before tubeless tape.

These are loosely intended to compete against the latest ENVE 4.5 SES Pro wheels. Now, I'm not the titanium police. So we won't go into the ideology, pros, and cons of using this materal for spokes. But just know they are available if ya wanna partake. Future details and pricing coming soon.

Just got my hands on the current Scott Foil RC Pro. Figured these wheels would make a lot sense. The full build with pedals, cages, and computer mount is somewhere around 6.9kg all in.

Are your attached pics of these TI spokes wheels?

Any indication of price?
God help me with this addiction!
