    Look on ebay.

    You will be hard stretched to find a brand new rotor for that, never mind an odd size like 185mm.

    What are the brakes and why do you need this size?

    You just need an adaptor then I think.

    Try looking around, I'm sure there will be a six bolt to centrelock adaptor somewhere

    I've not seen any centrelock rotor to 6 bolt hub adaptors about- I'm not even sure it would work...

    Happy to be proved wrong though!

    I haven't seen any either but there are so many other adaptors out there...

    Otherwise just save up the extra tenner or whatever for the Avid rotors or something else

    if you cant find one why not look at it another way.

    a new 180 adaptor and a 180 disc.

    and .... the problem is

    does your bike not already have 180mm rotors on it with post mount brakes? use them.

    i though all adaptors where different to the brake they were being used so one one adaptor would fit one brake
  • nicklouse

    well as all Post mount Brakes need to fit the Post mount standard the adaptors have to be the same in the mounting positions. yes some have issues with some clearance to caliper bodies. but 995 are fine.

    so try what you have now and then see what you really need to buy.

    if you have 180 F and R and they are post mount you should not need to buy anything.

    You are quite right to be confused - Avid do use 185mm rotors, which are only by them and some old hope discs I believe. You have 2 easy choices (plus no doubt a plethora of maddeningly hard ones) - get a 180 rotor and new mount, or a 203mm rotor and new mount. Obviously 203mm will be heavier but have more power, your choice really. Some forks won't take a 203mm either, but I think you should be ok.

    CRC have a good stock of IS/PM and PM/PM adaptors for 180mm, and for 203mm too. Superstar do excellent value rotors from under a tenner, so all in all you can do the lot for less than your £20 price point.

    Good luck!
