anyhooo....here's the plan. i'll write up what
i want in chinese and send it off the builder.

going with the 400mm steerer tube, cause a big stack of
spacers is too damn sexy. now i can dump both the inside
the fork tube riser and the bolt-on riser.

will have threaded eyelets on both sides of the crown,
for fenders and front platform rack.

will skip the disk brake mount. just so much extra
weight, and i've got a brand new deore hub that
should outlive me.

will have three threaded eyelets on each fork leg.

mid-fork eyelet will be 160mm from the dropout eyelet,
and will bolt on a tubus tara (clone). the next two will be
spaced at 65mm intervals above the mid-fork eyelet.

that lets me use a standard water bottle cage in the upper
position with small bottle when the tara has bags attached,
or can remove the tara and mount the bottle cage
lower with a large water bottle.
