but why would you do this? why go to the expense and trouble of finding the
perfect wheelsmith and source or custom-manufacture just the right components
from exotic materials? to what end?

save an ounce or so just so you can push the envelope, riding a loaded bike
or a grrrrrrrinder on technical terrain, with wheels right on the edge of
catastrophic failure? what's the point?

i'd rather go ultra-conservative on wheels if i'm touring, especially if on an
"adventure" tour....which in my case means jungle trails in laos or cambodia.
if loaded on a 700 i want phil hubs, 48 spoke 4x, 36 for 26". plenty of other
more sensible areas to shave weight.
