shimano br-561 - compatible pads

[swk9]

HI All,

I've got these calipers as standard on my Fuji Roubaix 1.3 road bike. I am looking at upgrading the pads from the standard ones that were fitted with it. Just a bit unsure on if there are only certain ones compatible with these types of caliper. I'm looking for better stopping power without paying a fortune.

Any help or suggestions would be useful.

Thanks

Kev
