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.
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.
