Greetings all,

I have been trying to find some sort of info that shows documentation -- aside from manufacturer PR-speak -- about the differences in friction between different chains (o-ring, x-ring, t-ring, no ring, etc.). This seems like it should be an easy test: Use a couple of different bikes, and run them identically with a series of different chains, checking the temperature of each at the end of the runs (since friction manifests as heat). If the two bikes show the same differences, I'd feel pretty confident that the test was good.

Am I wrong about the test? It seems so easy that it would be done by manufacturers if their chains were better than those of competitors. As is, all I can find is vague references like "up to 50% less friction."

Any independent info that anyonemight have would be appreciated.

another thing is the shape of the chain. Peanut or the other kind (cant remember the name)

 

Chains are a bit like anything else, you get wot you pay for. However don't believe anything that is self promotional, its wot they don't tell you in advertising thats the key " I got 200 more miles a tank running product X" (read: but we only drove at 10 mph the entire time) There is a lot of info on this site & on the web regarding chains. also remember, that its how well maintained they are, wot sort of riding you do, where you do it (as in road & weather conditions), and if you spend the money on a decent set of sprockets as well. I always seem to end up replacing with Regina chains myself.
