HG chain or KMC

Re:

You will be better using a 7 to 8speed type chain on a 7speed cassette, as these are easier to find. You could even use a 9speed, considering you're trying to flex your chain across 3 rings. Though, I'm not sure why anyone would want to bother with the pain of making a chain work across 3 rings as well as oscillating over biopace rings.

Anyway, let Sheldon be the voice of reason:

thankyou. I'm certainly using the stuff just because its on the bike! But those niggly Sheldon posts are now making me wonder whether I should be using bushless or bushed chains... aaaargh....

Re:

Now that is a dilemma – how about a roller chain eh? Last time I used a 3 ring Biopace set up was on my zolatoned Marin, which was kindly stolen in 1992.

ha ha! Well, for a 1988 bike, I was expecting an old dog, but curious about other posters mentioning superquiet, fine-pedalling, British Eagle Touristiques. And I agree with them. With original bottom bracket and front hub, even!

So the biopace is staying.

Re:

Just to make it a bit easier: most (I have no info on exact models or series) of todays Shimano HG chains are produced by: KMC.

Plenty of rings available new: Stronglight or TA. They are way better than Shimano (they use machined teeth for starters, Shimano STX were stamped) and last 3x-5x longer.

I found Shimano middle rings[the stamped ones] last way longer than the TA or Stronglight rings.
I assumed cold forging produced a harder tooth.
