Gone, gone are the days of uncontrollably barreling headlong into a group of hikers due to the complete insufficient braking power of my front 160mm rotor. No, today I am living a new life. With this adapter, I am now able to run the coveted 180mm rotor, which is precisely 12.5% larger than the 160mm but with 2000x the braking power. While enough stopping power to halt an F250 loaded with a southern family on their way back from a golden corral brunch, the stopping distance is the same because I inevitably do a front flip every time my finger grazes the lever. You will get used to this, harness it and the chicks will come.

I have shimano XT brakes and Wheels with the 180mm ice tech rotors. I bought this thinking it would have no problem fitting. I had to insert washers to space the bracket closer to my frame even though with my 6" rotors everything worked perfect. I still have a slight rub in the caliper. I am going to break everything down and clean it and see if that will fix it.

    Comments about Shimano 180mm Disc Brake Adaptors:

    Shimano makes some of the best and most versatile brake caliper adapters. I haven't found any brand of brakes that they don't work with (unlike some of the Hayes and Avid adapters). They may be a little heavy compared to say Formula adapters, but they get the job done right.

                            I'm not sure.  I was going from 160mm to 180mm rotors and these worked perfectly.  I think it also depends on the year the original brakes were made.  My bike was a 2014 bike.
