Rotor suggestions?

The two-piece Hopes have been real good for me. Formula is coming out with a similar 2-piece rotor also.

Stainless steel are created pretty well equally now a days.

There are some good aluminum rotors out there but you have to deal with limited life span, marginal performance in marginal conditions, and expense.

There is a thread about some metal matrix rotors in the weight weenies forum. Good reviews, but crazy expensive.

i've been very happy with my xt/alligator serrated combo. light, powerful and pretty cheap next to some of the other lightweight options. i'm 100kg, so i put a fair bit through them and i'm happier with the feel of them than my juicy 7s....

Alligator Serration rotors. They weigh ~90 grams. Work great with EBC gold pads.

I'm going to be mounting those on my new 29er race wheels, whenever I decide to build them up.

get the alligators if you can deal with some brake pad pulsing. i've had them front and back and i replaced the front with an xtr because i can't deal with the pulse. i don't notice it much in the back for some reason.

+1 on the alligators

i had pulsing initially running these rotors with deore calipers. when i put my xt calipers on it was still there. i had been running a 7" rotor with a 160R adaptor which meant the offset was very slightly incorrect (a few mm). i put the correct adaptor on (a proper shimano 180F) and the problem disappeared within a few rides.

could be worth trying a few different adaptors as a poor manufacturing tolerance on one may have been causing a problem. ymmv.

I'm running hope mono mini's with the correct hope adapters. 160 F/R. hope's tolerances are usually pretty good.

Not exactly true. While the grades can even be similar, manufacturing techniques first put different stresses in order to make different designs, along with the amount of braking surface area. Additionally, we're also finding out that some don't seem to be heat treated in manufacturing, thus being prone to warpage during use. Some designs also don't have heat capacities of others, and so on.
