Chains !?

[Mojoman]

I think I used to use KMC chains on my old Honda?

Had an interesting issue with a chain a few weeks ago on the road bike, 9 speed. Had a new 9 speed chain that had been lying around for about two years, bought on a special, and decided to fit it although the old chain ws not really that worn. (Yes, I was bored!)

Fitted the chain and went off the Saturday for the club ride only to find a severe case of chain slip. First suspected a sticky link, no sticky link.

Finally found that the slip was only occuring on one cog the 14 tooth.

Swopped this out for a new 14 tooth, same problem! Tried a 13 tooth, same problem!

Laid the old and new chains side by side, and found that the new chain had a completely different pitch, this was over a section of about four links.

Put the old chain back, problem solved.

Anybody ever had a similar experience?

Is there a difference in pitch between say an eight speed chain vs a nine speed? Don't think so, since the tooth spacing on the gears is identical?? (Thought that maybe it was a packing/labelling problem)

Shimano chain by the way.

I have had shimano and sram chains on my mtb and currently the gold x9 kmc, best chain I have ever had

Chains are a dime a dozen dont care what anyone tells you, just stick with mid range non hollow technology and youll be just fine, Shimano SLX exactly the same as SRAM 97X series, both durable good and strong. Anything more than that your just waisting your money. And anybody that tells me a Shimano is better or worse than SRAM or KMC can go eat their own dung, since they all made in the same facotry out of the exact same composite materials they just rebranded.

Any bright ideas on my chain experience. Have now bought a SRam chain and fitted it Sunday, works perfectly, no "skipping" on any of the gears.
