I use a lot of KMC K710 BMX/SS chain (1/8th) and have racked up a crapload of hard miles with no problems whatsoever on my fixed gear bikes, single speed coasters, and my 3 speeds.

It has a rated strength of 1300 kg.

It is strong as hell and very quiet and has become a favourite of mine and many other ss and fixed gear riders here as it is simply bombproof.

For 3/32 chain I use KMC X8.93 7 speed chain or Z51 7 speed chain and again, have had no issues.

I get my chain at cost but even at retail prices... a decent chain is all of $15.00.
