Shimano 105 CN-HG600/601 Kette 11-fach - ohne Quick Link

The outer plates of this chain rusted after an occasional night rain on my trip in Italy. My friend's bicycle stayed the same night in the same place, with no adverse influence on its chain.

I use squirt on all my chains, but experience such rapid corrosion the first time. Not the quality I am used to buying Shimano branded products.
