Hi there,

Has anyone ordered from these Aliexpress vendors? I'd be pairing these with GRX 400 Calipers on a gravel bike. 

The prices look good but I'm not sure if I'd be getting myself into an issue by ordering from them.

Comments on your experiences would be welcome!

Just a quick update on my order.

D50CU-33 w/new in-house straight through hubs & 5mm width carbon spokes are ready to ship. 

They look great in the picture and the weight is impressive.

Thanks all for your help and of course to Peter for being so patient and helpful with me as well as for making these wheels available.

That great that you disproved a BS 25yo wind tunnel test with an even more BS CFD analysis.


I actually skip wind tunnel testing and CFD analysis, I acquire a rim profile in a .jpg file format and scanning with my eyes I am able to calculate the aero performance of a particular tire-rim transition with a 100% margin of error

What specifically makes you say his particular cfd analysis is bs? I'm interested in seeing the details.  Maybe he has deep expertise and validation data at his disposal. Maybe not. idk.

Merry Christmas everyone.  I just got my order in for D50CU-33 with the 20H hubs and carbon spokes, ceramic bearings, etc.  Great communication from Peter and really looking forward to being able to see and test these wheels up close!

Thanks, Toxin.  That's consistent with the rabbit hole of research I've done over the last couple days.  Appreciate the thoughtful discussion here from people more knowledgeable than I.

I want to get my order in but I'm having trouble picking between 3.8mm carbon, 5mm carbon, or steel CX-Ray spokes for my T1100 D50CU-33.  I'm 60kg fwiw and assuming cross winds won't be an issue. 

The extra cost of carbon spokes is significant but if it makes my bike more fun but not noticeably less comfortable on 32c tires or significantly less safe then it's probably worth it for me. 

I'm just waiting for one of the bigger players to extend the bladed section and reduce the round section of the spoke of this design as much as possible. Carbon spokes have gotten plenty thin and deep already, so that's the biggest remaining room for improvement in aero. Eyeballing it, the stren spokes on newmen, scope, winspace, cadex, (crw? conflicting info) etc. have it the worst and farsports considerably better, but then they now have those gigantic external nipples, so swings and roundabouts, I guess. Wheellab do have something in the works apparently, but nothing concrete shown yet.

Thanks for your thoughtful analyses and comments.  I was just wondering what leads to the conclusion that the farsports version is better? I'm assuming you're referring to aero?

I'm also thinking about safety - it seems like none of the options really use bonding to hold the tension anymore which addresses my concern if it is true (I've had some bad experience with carbon adhesive pull-out in another application).

Do they think there should be no gap? What is the effect of the gap that they are concerned about?

Hello, I am interested in CS-D50CU-33 wheelset. 

-Where can I learn more about availability of hub & spoke options?  Probably DT240 & CX-Ray but would like to understand pricing for other options.
-Interested in your spoke drill & assembly QA/tolerances and lacing also.  (e.g. CNC drilled?)
-Also interested in surface finish options - would ideally like satin and unpainted ("paint-less") depending on the carbon finish but can also do matte black.
-Interested in pricing and assembled mass/weight.

Thank you in advance!

P.S. I'm motivated to upgrade my wheels but I'm also new here - if someone sees an opportunity to educate me or suggest better choices I'd appreciate it.
