well, i ran into this cryptic item in an article by thomas kunich (at http://www.sheldonbrown.com/kunich.html): "YST, a Taiwanese firm, makes a cheap copy of the older Mavic bottom bracket that has it's own internal sleeve and doesn't require using the bottom bracket threads at all. You merely tighten the ends and they pinch the bottom bracket into place."

so i did some research. this is the best picture i found of said object:

it looks pretty hot. and it looks inexpensive... too good to be true?

yeah.. the peugeot is sexy, for sure. maybe i'm a sentimentalist, but that's my shizzle right there. my first serious ride was a 1974 lejune. heavy as lead, but lean, tall, and graceful as all get out. it was like riding a russian wolfhound. i digress...
