I did a bit of research on the net and found this chain was recommended by several sites including the now-defunct 63xc.com. I have not had any problems with fitting the chain and, with regular cleaning, it appears to be resisting the elements well. Usual excellent service from CRC who were also the cheapest supplier I could find anywhere.
Usually when i put a new chain on my singlespeed bike i spend the first few rides gradually taking up the slack as the chain initially stretches quite quickly.
Not so with this chain. Put it on and ride, then ride some more. Still not had to take up the slack despite some serious torque being put through the chain.
This'll be my chain of choice in the future (assuming the current one does eventually stretch enough to need changing !).
Cheap, stiff, smooth. I use it on trials bike and it works good, especialy for this money. Just don't forget to replace it with new one after every at least four months of riding if you use it really hard.
