Product Story

IS mounts are the type with the mounting screws that install horizontally. We make them in +0, +20 and +40. Plus zero are for 160 front and 140 rear rotor sizes. To go bigger just add 20 0r 40mm. So a 180 front rotor will need a +20 and a 200 or 203 will need a +40. (160 plus 40 does not equal 203, but that’s ok).

The post mount version works the same except the caliper mounts to frame or fork directly through the caliper holes. For 160 front  and 140 rear, no adapters are needed. For bigger rotors, you will need the adapters.

HEY PATRICK WHAT ARE YOU DOING WITH THAT WEIRD MIC HEY PATRICK WHAT ARE YOU DOING WITH THAT WEIRD MICROFISHE LOOKING MACHINE?! “That’s our PJ-300 Optical Comparator. It’s a Mitutoyo like most all of our metrology instruments. (Metrology is the science of measuring). It projects a 2D profile image of a small part onto a screen with a grid. Using the grid, one can verify dimensions and inspect the part. It’s good at checking outer-diameter threads, as you can measure the depth of the thread (from the crest to root, so top of the point to bottom of the valley). So, you can check that depth on a thread chart to see if it is in range for the appropriate class of thread. We can also check groove depths, ect. It’s good at roundie bits. I also use it to check threading inserts and bore bars, as the tip of some of our tools are very sharp (little to no radius) which is not visible to my naked eyes. So it’s faster to check it (the tool) on the comparator then load it in the machine and make a part to find out the part is bad because the tool is bad.” Cool, looks fun, thanks Patrick!
