Luigino has come out with a new Striker frame called the Mark II Striker. It's a 4x90/3x110 frame. It works as both a 4x90 and 3x110 in one frame. So this FR1 skate is now coming with the new Striker 4x90/3x110 frame. The problem is, the frame slots or boot bolt holes are narrower then the old Striker frames. They need to be filed 1mm to fit the bigger Seba boot bolts that come with the Seba boots. I already got my Striker 4x90/3x110 frame and filed it out. I have it on my FR1 boot and like the combination. The FR1 with the 4x90/3x110 frame is my favorite boot-frame setup. I believe it's worth the 5 minutes it takes to widen the frame slots 1mm to make it fit. If you don't feel you can file 1mm out of the frame slot then you may have to look at a different boot-frame combination. But, this is my favorite setup, a comfort boot (FR1) on a speed frame (Striker 4x90/3x110) wheel (Matrix) annd bearing (Bionic).
