Xiamen Carbon Speed rims/wheels

[DrRoB]

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

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.

Could you share some photos of your wheels? Am interested how UD paintless glossy looks like on these.

Are carbon spokes worth it? I'm worried they ride harsh and are more difficult to tension due to less stretching nature of the material. Looks and weight are great - price also justifiable. But are they actually better as for ride quality, serviceability and longevity?

[McMadigan]

What do you think of the MARBLE surface?


Does anyone have rims with this design?


I find them very interesting.

Carbon spokes are only really better for weight and maaaybe a bit of aero, but they will in general ride harsher, harder to service, easier to break (I've seen carbon spokes break when the rider in front kicked up a loose pebble into the wheel of the rider behind). They will feel stiffer but it's up to you to decide if you want or like that. In my opinion, if Pogačar can win every race under the sun with steel spokes, I believe you can too.

How loud are the hubs offered by Xiamen Carbon Speed? Is the freehub very "waspy" sounding? I only ask as Im not a fan of loud hubs (maybe one of the few now).
