Xiamen Carbon Speed 10 years anniversary special promotion

@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!

I would also be very interested in a similar wheelset. How much would your above set cost?

PMd you.

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.

A wide rim in the 55-60mm range would make a perfect rear wheel to match with the 50/33 front, something similar to Roval CLX II or ENVE SES 4.5

Just ordered a D65CU-33 wheelset with 5 mm carbon spokes from Peter. I will report when they arrive.

It seems like xiamencarbonspeed is gaining some heavy traction. Even on a german forum more people are looking into them and are buying wheelsets. I hope xiamencarbonspeed can keep up their good quality to price ratio. Price hike upcoming with the increased demand?

Thanks for your attention and feedback. We are on Chinese Lunar new year holiday now, don't worry, as I said in my first post, we will keep up our quality products and service as over the years, I believe our top grade quality products are still most cost-effective, the pricing should be very reasonable.

i just got my xmcs d50cu-33 wheelset from peter, well packed. peter notified me item should have arrived, but i was away on vacation.

wheelset arrives at 1167g.
my setup:
- d50cu-33 with 20H straightpull spokes
- rt-cl900 140 rotors
- tpu tubes
- michelin power cup 28mm clinchers

the powercup ballooned to 32mm. powercup clinchers are inown/reported to size bigger than advertised.

already got 160km of ride on my tt912 frame(my x38 build got delayed), the front really absorb more road buzz compared to my 77/86 with fron gp5k 28mm.
speed wise i cant tell if its any faster to my 77/86, as different tires.
but in crosswinds, its so much easier to handle the fronts.
chainstay clearance kinda tight

chainstay clearance kinda tight 

That's a snug fit indeed

damn that's light... the more i'm reading through this thread the more intrigued I am for my next build!

Just another data point - my DC50U's on 20H 5mm carbon spokes and a Shimano freehub came in at 1180g, so a bit heavier than others.

Box a bit smashed up but the wheels were fine and ok. Seem true, haven't tested spoke tensions or ridden yet.

This was for UD paintless glossy though, so people buying without a coating on may save 10-15g.
