the 1098RR wets are steels/iron/whatever and the drys are carbon
Doesn't it usually run an iron/steel disk on the back all weather?
Just read this in a magazine today and remembered this post.
Cost of carbon brakes(in £ sterling)
Single disc £2500
Set of pads £1000
So for just discs and pads alone its already up to £6000 plus the usual cost of caliper, master cylinder and hoses.
It didint say how long a set of pads or disc lasted but it did say they needed skilled maintenance.

Thanks for your support
They run carbon front disks in the dry, but steel in the wet, as the carbon ones cool down too much.
The carbon ones (apart from offering fiercer braking and less fade) are lighter so less rotating mass.
As for drilled disks, yes, it's mostly just a fashion for road bikes, as solid ones have a greater surface area and better performance. Same with stainless steel disks: the iron ones (a la Moto Guzzi and older Ducatis) have better friction, but rust more, so the Jap manufacturers use s/steel.
Apparently grooved ones are more effective for dissipation of surface water in the rain, but they're much more expensive to machine.
... and that's what I think.
Or summat.
Or maybe not...
Dunno really....![]()
