LOL! Yeah, 120g is definitely wishful thinking!
@mitre_tester: I was about to go single-speed had I not bought the KMC X10-93. Such a setup would've definitely been with a wider chain.
My experience is that chain failure (with modern chains) is almost always a result of poor installation. Are you reading and following the installation instructions?
Who read those manuals anyway?!
In my 15 years of building exotic bikes there were never any issues with chain install, especially with the Sram's Powerlinks and KMC's Missing Links. Also, the derailleurs are always perfectly adjusted for clean and crisp shifting and upon installation chains always run silent. Install is not the cause. I did break some Sram Powerlinks though. I've not been using Sram chains since. Didn't Sram had a recall on them..?
Back in '04, I tried the Wippermann Connex 10TR Titanium chain, which I found not enough value for money to justify its cost of almost 300 euros.
I dunno what it is why my KMC chains kept on breaking. Possible causes:
- I shift a lot (to keep a steady cadence) and almost always under power. My average cruising speeds are often around 40km/h, sometimes even faster. I also accelerate a lot during rides never doing the same tempo.
- KMC chains are really greasy when purchased. As I hardly do maintenance on my SL Gold chains. When they become dry I have to lube them over and over and they turn black with dirt rather quickly. Most ProTour teams would replace the chain when this occurs.

You can't really blame the chain if the hangers failed, or is that the hanger failed due to the chain or shifting problems?
The derailleur hanger failure was the result of some heedless idiot knocking my Scott Addict over in passing while I was briefly inside a store. I didn't even see who did it. When riding home, I noticed that my RD didn't shift so well anymore. When I ordered news ones, I kept on riding and it happened to break a few days before I got my replacement hangers in the mail. There were bents in the inner links in 4 places, which otherwise still have a lot of miles life left in it. I'm just really put off by the umpteenth chain failure and now I'm looking for something a bit more bulletproof out there.
I found some info on the Yaban's SL210-G chain
. It said:
New Material- SFL
SFL means “Self-Lubrication” YBN took two years devoted to explore SFL new material and new treatment in order to offer customers the best chain products. SFL material has awesome Anti-Rust function. It is better than the treatment of surface Titanium Nitride coating and CP coating. Moreover, SFL material is not only extremely smooth, noiseless, easier to clean but also prolonged 100% using life of the chain.
It is not necessary to put oil on the SL210 Titanium chain again after you clean it. Furthermore, SL210 Titanium chain is not only rust proof but withstand the violence of 300 hours Salt Spray Test without rusting. It is extremely light, smooth and noiseless. The Impressive characteristic of SL210 Titanium chain is durability. The using life of SL210 Titanium chain is twice as long as a normal chain (6000~8000k).
Chromium Carbide Surface Treatment - DHA Treatment
Cooperating with Taiwan Chung-Shan Institute of Science & Technology, YBN is using the technology of Chromium Carbide Surface Treatment to increase the hardness of pin surface. Excellent performance can be expected even in adverse conditions, including the presence of abrasive contaminants. Furthermore, DHA pins have excellent protection of rusting. Chromium Carbide Surface treated chain pin is able to prolong chain 300% using life. Chromium Carbide treated chain won’t be elongated easily.
Could be worth a try...
