So, I recently bought a new front brake (Shimano MT501 I think), ordered a 203mm rotor and the Shimano adaptor, however the disc fouls the caliper and I can't fit the front wheel on the bikie ike, I have added some images to help see what's going on, I'm at a loss, can anyone help?


Please note the adaptor fitted in the above photo is the old one to allow the 180mm rotor to be refitted.

Cheers

    You have a 160mm post mount fork. You need a +43mm adaptor to go from 160mm post mount to 203mm rotor. The one you have tried to fit is a +23mm 180mm post mount to 203mm rotor.

    I remember your previous posting I answered on 'Moving to a bigger front rotor' where you said your caliper fitted straight onto forks with no adaptor?

    This is the one you need:-ISMMAF203PPA

    That'll be why the bloody thing wouldnt fit then 😂.

    Thanks for the quick response, all ordered and hopefully will see it on Friday.
