ok, keep it the same length as an xc, just machine the slots pro2 stylee, if you get me, so the pair that engages are opposite each other. have 3 pairs of 2 pawls, that'd be beast.
um, i have a curtis t1 comp. it rides fecking nicley to be honest. always able to reweld and modify the bike aswell if its steel, just a bit pricey. iolo could make you a curtis geo for like half the price.
you know on ff bikes the lockring comes undone?? well, by making the thread opposite it tightens instead. now, on the rear the forces are reversed, so a freewheel that tightens the lockring on the back will come undone on the front and so on and so forth.
