  • PM to IS adaptor – do I have to increase disc size?

    If I was to buy some forks with a PM and I have an IS Caliper 180mm Louise FR up front would I have to increase to a 203mm disc with the PM to IS adaptor or is there an adaptor that would allow things to stay as they are?

    Cheers

    Pretty sure they're all plus 20mm i'm afraid.

    Had same problem.. Had to get a new caliper 160 so I could run a 180 rotor again

    Giant made a mount for the MPH brakes which fits on some other brakes which doesn't increase the rotor size. Really odd zigzaggy shape. A giant dealer MAY be able to order it as a spare part. It's a couple of years old now so may not still be available. Good luck!

    have a look at the Hope brackets, I thought they did one with 'hidden' bolts?
