I thought of drilling the underside of the rear fork "crown" (it's a wishbone stay design) and tapping for an M5 bolt..
Would this work with those big clearances?
Why not just get a crud catcher. The rear guard is surprisingly effective on my cycloX frame, and in a MTN frame you should be able to position it lower. The down tube guard thing is'nt that effective though. I'm only really using it to keep the road slush from collecting too much on my body.
PS: have you checked heel clearance with the newly proposed chainline? If it were me I'd be tempted to go with say 47mm chainline regardless. I like the sound of a fixed allweather inbred, keep us posted ;)
