    2013 Rift Zone XC8 Rear break upgrade question

    Hey guys,

    I recently bought a Rift Zone XC8 with Formula R1 brakes. 180mm in front and 160mm in the back.

    Can I upgrade my rear disk to 180mm?

    Yes. You just need to buy a bracket to space the caliper further away.

    Hi, I contacted Formula and they told me that the adapter you would need would be a PM 6" to 180. There is also a PM 6" to 203 which is part number FD40150-10 for 203mm rotors.

    This will probably help others in the future.

    Thank you for the input and help!
