Xiamen Carbon Speed rims/wheels

[PoulB88]

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.

I'm still considering these with the 65mm rim (T1100 or T800 TBD), has anyone ordered this configuration?

Also regarding spokes, is there somewhere to compare the different carbon options?

Usecase: Spez Venge '20, road racing flat/tiny hills. 30mm tubeless GP5000s. 82kg cat C.

D65CU-33 T1100 20/20H UD paintless wheelset built with 5.0mm carbon spokes weigh around 1315g/pair, sorry, not able to attach pictures for now

In case if there is anyone else interested in the "old school" rim brake version mine just have arrived.
R50TL-26 tubelss compatible rims / 19mm inner width / 26mm outer width rim brake rims 20/24H UD matt
Total weight 1410g
Wheels look amazing. Because of the weather, I will need to wait few more weeks to share something about the ride feel, and braking performance (my biggest worry).

Quite frankly I have nothing negative to report or criticize. Easily the lightest and best set of wheels I've used from a value perspective. Mother nature gave me one single day today above freezing, and I was able to get in a 3 hour ride Z2 ride with some intervals mixed in.

GP5000 STR 32c. Running actual tubeless to avoid another audience upheaval on my YouTube. Tires measure 34mm at the rim. 55 PSI

Video drops next week.

These vs the CRWs and Farsports S5?

Look great, can't wait to see your video on them, seems like we all went with gold decals

Please test them with TPU tubes as well, so you can compare to everything else you have ridden!

Sent you a PM about wheels. Maybe a email would be better ?

Looking forward to the review Pat, they look amazing on the SL8 too, I thought they might look a bit too wide but not the case at all.

Curious if you will notice a difference in feel with the GP5000 STR tubeless, instead of with TPU tubes. I bought a new bike with the STRs + TPU tubes and they felt so...numb I guess, coming from the GP5000 clinchers+TPU's I was running on my other bike. I even noticed when I flick them they would give a dull thud, where as the clincher+TPU would give a nice balloony 'ting'.

I'm currently on Shimano C60 wheels, but would gladly consider selling them for these if they seem good. Save myself 250g or so, wider profiles so I can comfortably run 32mm tires for that smoother ride!

@Peter: Any chance you will make a rim with 34mm external width but more like 23mm internal? I think an inner width of 26 is excessive for road tires. Even for 32s it's a bit much. And personally, I also think it hurts comfort. If tires are too stretched out on the rim they don't feel as supple anymore. Tubeless helps. But it would still feel better with a bit less internal width, IMO.

We might consider to make 23-24mm internal width rims this year,  but I don't think outer width on these rims would be 34mm that wide, it should be around 31mm.

Finally got my hands on the wheelset and so far I'm happy with it. 65mm rim with 26mm internal with in-house hubs and pillar 1420 spokes weight just under 1500g. The paintless finish looks fantastic. 30mm Schwalbe Pro one measures around 33mm and sits flush with the rim

After using this wheelset for hundreds of kilometers, I'm quite happy with the wheels overall. There's one drawback however worth mentioning. I use my tires tubeless and when deflated, the bead tends to unseat probably due to the width of the rim. It might not be a problem for most but since I travel a lot with my bike on the plane and you are always required to deflate the tires that's quite annoying. Once unseated the sealant starts leaking and you have to seat your tire at the destination and I don't carry a floor pump with me. I'll try adding a bit more sealant and hope it will glue the bead in place.

Apart from airline regulation there is no real reason to deflate tires for flights. Airline has never checked mine so have flown with normal pressure.

How much did the wheels cost you if you don’t mind me asking?  Looking for a budget set of carbon wheels for my old CAAD 10!

Thx

Meant to reply to this ages ago, and seeing Patrick's YouTube today reminded me...
Peter kindly agreed to make the following for a monster gravel bike, and the results are absolutely brilliant...

D40CU-33 T1100 rims UD paintless 28/28H
Carbon Speed in-house ratchet boost hubs with steel bearings 6 bolts straight pull for 110*15/148*12 with Shimano HG driver
Sapim CX-Ray spokes
Sapim self-securing brass nipples

Had a month or so on them now and they've been great!
Thanks again Peter, outstanding wheels!
