Looks great! Could you post a closer picture of the unit holding the front caliper cable? That looks very interesting.
As far as knobby MTB tires go, I've never ridden one I liked. I much prefer a smooth tread fattish 26" tire and fenders. Started mounting Panaracer Street Wise (IIRC) and fenders on my '88 Schwinn High Sierra last night. Two rides on the old knobbies and I was covered in trail dust and rocks!
