Crud Can't find the link I had. It explained all the tech specs and different pieces of the chain and how they work, etc. Oh well Like I said, our bikes don't put out much power and use a large 530 chain. If you get a good brand it will last a long time if you just clean and lube it regularly.
I switched over to the Tsubaki Omega 530 102 o-ring chain a couple of months ago on my B5. At the same time, I upgraded the front sprocket to a 18T. It was a huge improvement in the ride- the shifting was far smoother. I can't attribute it all to the new chain- more than anything it was probably the sprocket upgrade, chain slack adjustment, and rear wheel alignment. But I'm really happy with it and would definitely recommend it.
