Hi all,

Wondering if anyone can help me with this question before I spend my money on a different mount for this caliper.

I am going to increase my front rotor size but what is printed on the side of my current mount has me confused. It says 160mm or 180mm implying that this mount can be used for both but surely the pads need to be in a different position for each size of rotor? I can't just bang a 180mm rotor on and change nothing else and expect it to work fine can I?

Can anyone clarify for me what this text on the side of the mount is getting at, am I able to use this mount for the bigger rotor somehow? If so how?

I plan on taking it apart this weekend and trying it out for sizing before I order a different mount but in my mind the caliper would need to be pushed further out to make space for the increase in size for the rotor and was hoping someone could enlighten me on what this text actually means whilst I plan the work in my head :D

That’s a 160 mount. Just search amazon for 180 flat disc brake mount and you’ll find a bunch that will work for you.
