Will it fit on my Onza T-Pro I looked on Tarty Bikes and there seems to be a few variants.

My rotor is 160mm

Thank you.

The ebay link isn't working. You are going to use the brake on the rear or front?

If it's for the rear you probably need a 3# calliper with an 160mm rotor

it's a #3 caliper so the smallest disc you would be able to run on a standard (IS) fork mount would be 180mm, so unfortunately you'd need to purchase another rotor if you plan on using it as a front brake,

it would work fine with a 160mm rotor if you where going to be running it as a rear brake, but you'd probably have to change the hose in order to use it as a rear.

:) It better fit because if it doesn't I am going to cry.

EDIT: Ok so all i need now then is a 180mm rotor? It doesn't matter that I had a 160mm before? I am just confused because wont that mean that the mounting point would need to move further out becuase the disc is increasing in radius.

i'm guessing that your forks have a standard IS mount ( due to you prevously running a 160mm rotor ), if it is a standard IS mount then you will need a 180mm rotor due to your caliper being a #3, if it was a #5 caliper you could of used your 160mm rotor,

the reason why you where able to run a 160mm rotor with your old brake was because your caliper was designed to run a 160mm rotor mounted on a standard IS mount,

your new caliper has larger/longer mounts meaning that it sits 20mm further away from your forks.
