These just arrived for the bike going to NAHBS.

160mm-F/R Formula 1 piece rotors they're replacing were 118g each!

Give us a review once you've abused them.

Yes a review would be nice, but I'm also interested how these look on a bike. Thinking about a set as well.

MSC Koncept Carbon Di2 - 6955g

Same here :D
But, how do I mount them in a centric position? That is easy with round holes for the bolts, but these only have slots ...

Sweet. I jumped in right at the beginning of the KickStarter campaign and am hoping to receive my 160s but have not heard/seen anything since I was prompted for shipping information while I was at CX Masters Worlds.
Michael - The Anaerobic Threshold is neither...

My guess is they will be mounted at the end of each slot so keeping them concentric to the axle shouldn't be a problem..

I'm curious as to how these work as well. We've done carbon rotors but the limiting factor is the operating temperature of the resin. Carbon-carbon or preferably carbon-ceramic would be the way to go but they're usually very expensive. I'm curious as to the structure of these discs.

I have the same question you do, Stephen. In all the coverage/discussion, I haven't seen a full description of the materials involved. Maybe the Kettle Cycles guys will be a bit more forthcoming once they've shipped some product.

Cheers,

Jason

Here's the description off their website, http://kettlecycles.com


One piece SiCCC SFL rotors

There are two versions of this amazing brake rotor.
The lightest being the single piece SFL SiCCC Rotor.
And the more economical, more customizable two piece SiCCC rotor.
The two piece features a carbon fiber spider and a SiCCC braking outer ring.

SiCCC material, what you need to know:

- Silicon Carbide for bite, Ceramic for heat management, Carbon fiber for strength.
- Dial in the initial bite you want depending on pad selection.
- Wonderful modulation.
- Drilled holes or vents have no performance benefit.
- No glazing or material property changes under even the heaviest use.

Waiting for Ashima alloy bolts, but just mocked up with one bolt so you can see they fit like any other rotor.

Yeah, thanks. I've seen that, though I appreciate your posting it. What I haven't seen is an explanation of why the exterior looks like a plain carbon weave. Neither silicon carbide nor most ceramics are transparent, but most resin systems *are* transparent. I would expect a mottled appearance, but what I see looks exactly like a disc laid up with a standard epoxy resin.

I'm not saying that's damning in any way. I'm just saying I still haven't seen a full description of the materials and construction, and I stand by that for now. I'm sure everything will be illuminated post haste.

Cheers,

Jason

That's a place I wouldn't use alloy bolts, just for peace of mind.
The storm rotors I'm currently using came with alloy bolts, anyway I did use Ti bolts on them, weight savings are minimal.
I'm waiting for the second batch of SICCC rotors.
