I'm pretty sure that there are SBS pads in there just now as they were changed out before I got the bike.
I use these EBC pads on my track bike Colin. They are stunning! Only down side, is that they don't last very long and are expensive.....But so worth it!
I am using brembo rc, they are great pads but dont last very long and are quite expensive. I am considering using brembo sc this season.
