What is the difference between a 15-195 shoe with a closed or 15-195B open cam? Does it make any difference which I select?

Thanks for writing in. This is a very good question. It actually does make a difference. The 15-195's cam has a 'wall' in the back, whereas the 15-195B cam you can see 'through', hence Open Cam. The style of this cam affects what pivot bar is compatible with the shoe, so it certainly is best to choose the correct one. 

The 15-195 comes installed by default with our Series 795 Channel Balances; if you need the 15-195B or a different shoe, you can buy it separately and swap the shoes. See the video below.
