Xiamen Carbon Speed 2025 new carbon crankset

[aeroskiii]

Dude, relax. Yes, it is helpful to know the weight of the gold standard crankset when considering buying a premium avant garde piece of kit.
I wouldn't worry. 100kg isn't THAT heavy, and i suspect you're not a track sprinter. Don't buy ultra lightweight components, like these cockpits that are pool noodles because they weigh nothing. Ditto, dont get feather weight aluminium cassettes. You'll probably wear out chairings fast if you get chinese ones, but they're cheap.
These carbon cranksets have been around for many, many years, i've had a sram red carbon crankset on my rim brake bike for a million years. As long as there's no manufacturing defect or dumb design (raceworks had a dumb design), you should be fine.

Just giving him a hard time

Any update on the Chainrings Peter
Specifications?
Sizes available
And price?

[Lotnik]

I'm interested too in the chain rings. Are they with carbon body or just carbon sticker like Cybrei does?

LOL I didn't realize they were a sticker. I guess I could just slap on some 3k carbon wrap I  have kicking around.

It's not. Its a carbon front plate , bonded to an aluminium backplate. The point is that the carbon plate gives you strength and aluminium gives durability and shifting performance

Sry, was referring to the Cybrei ones.

So was I. And from the pictures I'm pretty confident in saying XMCS ones are the same type of design.

Hi Peter! Do you have these cranks available for purchase? What is the price?

Peter's are for sure. I was in contact with him a month ago after I bought a frame from him and some wheels. I asked him to message me when they are available. I want to use a 1x with the R01 I bought.
