IS mounts are those where to bolts screw in perpendicular to the frame and you adjust caliper position with washers. Post mount are what you find on most modern forks and the bolts go in line with the frame allowing the caliper to be shimmied from side to side for correct positioning. Post mount is becoming the norm on forks but mainly IS on frames.
