Xiamen Carbon Speed 10 years anniversary special promotion

[TommyGun]

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?

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).

I asked for simple small logos with ud paintless glossy.

I've always thought that the matte carbon look just has a cheap open mould feel to it. I get it's the lightest option. The finish is really quite nice though on these.

My main worry is of course that they just won't survive the first rough road surface I hit nor will they survive the gravel racing I have planned. That and I won't be able to get a 30c tyre to meet rule of 105.

However, they were competing for my money with some LB Turbo 50's. To get the turbo 50's competitive in weight meant alpina hyperlight spokes and dt 180 hubs. That was 1980USD shipped (and that was at black friday prices, normally more like 2100). These were 870USD shipped.

I got one of the "new ones" and it was (fortunately) quieter than I expected.  I think you can change the sound significantly by packing with grease.

I will buy only carbon spoke wheels from now on. Have now already several carbon spoke wheels and the differance is noticable. Much better acceleration, stiffness,... And I find them just as comfortable as steel spokes. And if one worries about that, just drop a few psi in you tyres. The rolling resistance differance will be practicly zero, but you add comfort.

Service? Still not needed. And 2 sets have +10k km, and one set a bit bellow 10k km. I have about 80kg and do lots of steep climbing with lots of out of the saddle outbursts.

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.

Pat yo, love the video dude amazing now I am more drawn into ordering one,
If you could tell us the specs of the custom wheel build you had on your video? so I could replicate that?
Looking to get that 1200 1100gm wheelset heck even 1000gm with 40-45mm depth combo if ever that option exist with Xiamen Carbon Speed

[TommyGun]

¸..... 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. ......

Did someone elso also notice that?
When deflating, that tyre comes from the rim bed?

This is kind of problematic issue. Not only for traveling, but also for simple periodicly sealant check. And with possible bigger puncture, you probably cannot just insert a plug, as maybe you will not be able to seat the tyre with mini pump or CO2 cartridge.

Thank you sir. These are the rims below. Just let Peter know the specific specs for the lightweight version/hubs/matte finish. Or that you want wheels similar to mine, and he will take care of the rest.

Its a giant safety issue on the road. Good grief, they almost banned hookless in the peloton over this. New rules require strict ETTRO compliance regarding tire size/internal width. So I don't know if was the poster or the rim, but that needs attention.

Definately a big safety risk.
I think I heard from some CRW wheels users also have this issue.

One person here is running a 26mm internal width rim and a 30 mm tire. Any chart I seen recommends a 35mm tire. At the end of the day people will do what they want and blame the product for their choices.

Pretty sure ETRTO or whatever is 5mm greater than rim width.

Obviously, the issue here is finding a 32mm tyre that doesn't blow out beyond 105%.
