I’ve been running these rotors for quite some time now and I haven’t noticed them. They’ve quietly done their job with no fuss whatsoever. This is exactly what you want from a brake rotor.

So is that it? No, these rotors are special. Look at them, they’re full of holes. Some might wonder if this has caused reduced stopping power, or premature pad wear perhaps? No, none of these negatives are present.

They are made from 410 stainless steel, heat treated to 42HRC, and then double ground (for any metallurgists out there).

The large holes make them exceptionally light. I’ve been running a 203mm/180mm setup which weigh 136 grams and 112 grams respectively (A Hope 180mm rotor is approx. 160 grams). They rarely squeak, and mud is quick to clear. Apparently, due to the increased airflow they don’t heat up as much either, which makes sense. That’s difficult to tell but it could make that miniscule difference if you suffer from brake fade. I did once burn my leg on one of them, it still felt hot.

As well as the silver, they come in gold, black, or red.

Overall: Lighter than the rest, they just do what they’re supposed to do whilst looking cool.

    shot down in flames question? would these fit hope brakes (mini) if i wished to change disc’s

    I found that they heat up much faster due to the lack of mass. They also eat pads. I wouldn’t buy them again.

    There’s no reason why not, as long as the diameter matches what you currently have.

    is it me or is there next to no material around the bolt holes?

    sorry but i’d rather have the 48 grams of metal

    I’ve got a pair – one with an avid juicy 7 caliper and another with a Formula Oro. No problem with the Juicy but with the Oro I get an ‘ABS’ effect – ie pulsing in the braking effect and it takes a longer / stronger pull to get the same braking effect. I think it’s something to do with the small pads in the formula – they’re just slightly bigger than the holes in the rotor. In the end I took it off and got a XT which is heavier but stops better.

    I’ve been running these on Elixir’s.
    I agree with above story, they are awesome, they look cool, they are strong.
    I don’t think they need anymore metal, they keep everything cool. But no wonder.

    Buy them, use them, race them.

    Look great, super lightweight but they bend easy, so careful

    I can think of a good reason to not want these rotors:

    At the risk of being shot down – is that a rotor fitting fail? It’s on backwards!
