10-This pad is sold as a single pad on this site as it sometimes will be sold as two pads or it will also work with a similar pad without the hooked end that you will also find on this site. Also fits many disc brake calipers for many other models. Therefor if you order 2 of this pad along with 1 set of the rear brake pads for the Tank Touring 150DE you will end up with 2 sets. Hopefully this makes sense.
