If you wish to find out what disc pad you need, so long as you know what brake system is on your bicycle, then you can select it from this website and it will show what brake pad you need. When you open the website, select the brand of brake system, then you can select "View all brake systems for" and go through the list until you see your model of brake system.
Another way is to take your current brake pad out from your bike and compare the identification code on the brake pad.
