Ok, I looked again. There is NO holes in the top tube or seat tube. The only hole near the rear shock is at the bottom of the frame. Is the for drainage? (see pic). I'm still looking for a rear shock that fits. My choices are 165x38 Fox DPS (standard mount) or 165x42 Fox DPS(Trunnion mount). Has anyone had luck using spacers in the rear shock to limit the stroke? Thanks.
