"Wayne Stetina, Shimano's R&D manager, says, "If you remove the chain when it is only halfway worn
out and flip it over," he says, "you will double your chain life." In other words, your chain will
now be turned inside out. The other side of the rollers will now contact the gears, and the
derailleurs will now be laterally bending the chain the opposite direction. Stetina says that
Shimano engineers discovered this phenomenon quite by accident."

Zinn's claim that a worn chain will ruin new sprockets in a single ride makes me wonder about the
rest of his "good advice" that he has in his new book that is promoted in this article. It seems
this is a book for entertainment filled with myth and lore. A good read in front of the fire on a
wintry night.

Hmmmmm....

"Crankshaw", eh? Somehow seems appropriate 🙂

Please go out and buy a 180 NDS crank, as your left leg has been pulled.

He also speaks of $80 chains, perhaps they're reversible by design.

That is correct. (But it's only the $80.00 chains that are reversible...) 😄

So ... is it better to buy one $80 chain that is reversible, or two $40 that aren't, or should I
just go out and buy a $400 Ti chain?

C.Q.C.

Those would be the new Swiss Moebius chains. They have extra flexibility built into them so that
they can be installed with a half-twist in the tensionless underside, thus continuously reversing
themselves.

Available soon in either left hand or right hand twist versions, depending on your political
persuasion.

Designed by Escher, correct?

Actually, it's a myth that political persuasion is a factor in determining which twist to buy. It's
a coriolis effect issue.

If you get the twist opposite to your coriolis-effected draining water direction, then the chain
encounters those forces in a harmless perpendicular angle. If you get the other twist, then the
nearly parallel forces will quickly wear your chain.

This is why some people don't believe that the moebius design doesn't work...they had it
twisted wrong.
