wow, nice work bringing back a 5 year old thread...... and do you not know what google is at all?? i mean are you joking all you have to do is type in look px12 jib on google,ebay,ask,yahoo. and you could find like 50 diff things that tell you how wide they are. and no, they would not fit your sfb's you will have to get wide brakes for them... and im fairly sure no stock binding brake would fit over those skis... and im fairly sure they are 80mm stock brakes.
