    XTR 2011 Caliper with other Rotors?

    Hi Guys,

    Please forgive me in advance if this question has been asked, i was searching around this forum and managed to come across the thread regarding the compatibility of Shimano's rotors with other calipers (but not the other way around).

    Anyway, i've just recently purchased the XTR 2011 Grouppo and the new Ice-tech rotor(being Shimano) is only avail in centre-lock option.

    As i do not foresee myself changing my Hubs just to accomodate this bloody rotor, i'm wondering if any of you here have successfully used a different aftermarket rotor, such as aligator or ashima with the new XTR calipers

    Or should i just get the XT ST-76 six-bolt rotors from Shimano ?

    I thank you all in advance for your kind help and input in this.

    Rgds,
    Roths

    I've been running 6-bolt RT76 rotors with my 985s for the last couple of months with no worries.

    Still can't get replacement pads though... but Avid Elixir pads go straight in.

    I ran the newish 6 bolt Shimano rotors for a while and they work well but Formula R1 rotors work just as well and are lighter. As for pads, aren't the calipers the same as 2010?

    Nope, the calipers are different... as are the pads.

    So if the new Xtr's use the same pads as the Elixirs and the older Shimano rotors have a narrow brake band width compared to Elixirs wouldn't the pads contact the older Shimano rotors well into the spokes of the rotor? Just something to chew on anyways.


    (Last I checked Shimano rotors don't play well with Avid calipers)

    They've been fine for the last 1,000km or so, but thanks for your concern.

    I don't want to sound rude but my concern was not for you. It was for the op you already spent your money and what might be "fine" for one person might not be optimal performance for another. I am all about mixing rotors with different brands but am not sure on this one.

    Now that's proof, looks great, and I take back my argument!! Now that being said I would get Formula R1 rotors, cheaper, lighter, and pretty cool looking.

    Maybe that's due to the caliper, not the pads. So, when Avid pads are used in a Shimano rotor thy line up with the rotor just fine.

    No, oil flow should be high enough that it brings air with it.

    I'll agree though that it's not the "usual way" and some might argue it's "error prone".

    I'm sure it will all work fine... Shimano tends to test their stuff before deployment...

    But typically you put the bleed valve at the highest point because little bubbles WILL accumulate in the caliper. You won't be able to get those bubbles out of there without flipping your bike on end.

    One lever stroke will not be enough to clear all the air out of that hose hanging off the bleeder, so the bubbles will rise back up and could potentially get sucked back into the caliper...



    Just seems like something that wasn't broke, so why fix it?

    And of all the things they could have fixed, why not get rid of that stupid circlip?

    The bleeder used to be next to where the hose entered the caliper. I guess bubbles at the far end of the caliper could get stuck there so they put the bleeder at the far end, helping oil to flow through the whole caliper. If bled the way they show it could be very effective. Not as easy to do a quick, on bike bleed (especially with discs in place) but maybe the need to do frequent bleeds is a thing of the past now.

    Doesn't matter to me cuz Shimano already lost my brake business. I have 3 bikes that have all been converted from Shimano to Formula over the last season.

    What I do on my GFs XTR is that I open the port enough that oil flows freely. Without touching the lever and I simply add new oil at the lever to replace the old one. Once I went through a couple of reservoirs of oil (when it starts to look clean), I close the port and everything is fine.

    Why the change over? Im currently running sram xx's and thinking of changing, what turned you off Shimano?

    They frequently lost pressure and went right to the grip. I actually had this happen in some bad places, like the middle of a Super D race. They couldn't handle heat. They needed frequent bleeds. The XT was better than the XTR, but it could still get inconsistent and needed attention. Neither had as much power as I'd like either.

    The Formula The Ones and R1s have been perfect and maintenance free.

    Looks like i am not the only one paranoid about the brakes, i initially thought it was only me .

    I can totally related to the loss of pressure, happened to me once i was bombing away downhill . Got the brakes re-bled and rode 4-5 times without any issues. Hope its fine now .

    There's lots of people on here with reports of XT, Saint, and XTR levers going spongy. they're the only brakes I've had that problem with.
