Which disc rotors for muddy conditions?

[the_marsbar]

Yesterday's race was so muddy. I'm sure the Shimano pads with fins didn't help... But I think also the Avid HSX discs I am currently running are not working very well in the mud (sand collects in the holes).

Any suggestions for rotors that work well in muddy conditions?

either almost completely solid, so there is no where for mud to gather on the disc. (Cheap Avids fit this description) and i've had some luck in very muddy conditions with the current hope discs, they seem to shed mud effectively.

And i've heard (but not experienced) that the stock shimano pads aren't amazing for CX use, more geared up for road miles.......

I'll look for some of these solid Avids. I have Hope Race X2 discs on my MTB, they don't look better, but might give them a try.

Thanks

Avid Solid Sweep would be perfect. The extra weight doesn't really matter when the bike is packed with mud anyway.

When it's muddy....run sintered pads, period. They make a huge difference.( I get the ones without the fins because the fins don't do much in a slow muddy cross race...and they are cheaper)
As far as rotors....bigger holes actually work better in mud as the dirt falls out as opposed to filling up the small holes.
Solid rotors like those sold by Bikeman in the US work well also.

I've had no issues with the RT99 ice tech rotors and stock shimano pads.

Semi-Metallic pads do work a bit better.

Avid solid sweep is the best if you can find them. 2nd chaice is the SRAM centerline.

Our team is using Centerline front and solid sweep rear, both in 140mm.

Thanks for your replies. From the information above, I seemed to have used the worst possible rotors (Avid HSX has a lot of small holes).

160 mm Solid Sweep rotors seem hard to find, so I might try the Hopes that I've currently got on my mountain bike first.

The rear brake pads were almost worn out. I would not be surprised if the finned brake pads that I was running made matters worse (they came with the bike).

Best rotors Ive ever had were the Shimano RT99.

They only come in CL, and are easy to bend, but stopping power in all conditions 100x better than anything else.

For muddy xc riding I have ice tech rotor and finned pads. Works well for me. It's pretty claggy at the moment.
