No, you can use it with any GoPro combo mount. In the picture I'm using a Garmin VIRB mount but have also used it with a K-Edge combo mount. There are generic ones on Amazon and Ebay too. The Blendr system uses the std. GoPro spacing to mount the accessories to their Blendr bases (the part that does require a Bontrager stem) which is handy since you aren't locked into using their system.
