    Plz help me find the right adapters ( Shimano XTRs)

    Bike : Stumpjumper FSR Elite 29 2013

    I'm about to buy some mighty XTR Trails brakes and i need the whole package : rotors and adapters.

    I can keep looking at the XTR equipped Sworks Stumpy FSR for hours but I still can't figure out wich Shimano adapters I need to buy. Let me go ahead and try :

    front : IS 200 ?

    rear : PM/PM 180 ?

    I've got the money burning in my pocket,I can't belive there's just two stupid piece of metals holding me up.

    Just did the same thing this weekend, except with XT on my Expert 29'r. PM 74mm to PM 74mm front and back, sized to your rotors. What is your front fork? If it's a Fox, its 74mm Post Mount and not 51mm IS.

    Yes it is a OEM Talas Fox. So what you're saying is I can look for the same adapters for rear and front both PMs ? Front rotor is 200mm rear one is 180mm.

    Great !! Thanks,rep given. So I would assume the rotor's size is printed on the adapter like Avid does,is that correct ?

    That took a long time to finally get round to fitting Shimano brakes.

    March 2012
    Need help in swapping from Formula R1X to Avid x0(Epic 2012)Rep given.

    You'll need post mount adapters front and rear, along with Shimano RT-86 Ice Tech rotors if you're using six bolt disc brake hubs.

    The Shimano brakes have quite a distinctive feel so it's worth practicing gently bringing in the brakes to find the bite point when you first get them. Going down a road descent where you can feel out the brakes response as you apply them on and off initially is a good start.

    Putting some light oil on the servowave cam inside the brake lever makes the lever action a lot smoother also.

    Once you're used to them complaints about lack of modulation and grabbiness shouldn't be an issue. There is a learning curve though.
