KMC 415 Chain
HIGHS
-IT WILL NEVER STRETCH
-It will never break
-Can't rust
-You can grind on it
-You will never need to buy another chain

LOWS
-Expensive
-Heavy
-I have heard it rubs some frames
-Danscomp says it is not compatible with ACS and Shimano f/wheels.  But I have
seen it used with a Shimano 17T f/wheel and it works fine
-You need a special chain breaker


OVERALL
If you can afford it and can stand the weight  it is an awesome chain with a
hint of "overkill" that will practically be the LAST chain you ever buy.
