Been looking at this- is there any gains benefits
Pros/cons? 520 chains seem cheaper than 530
Even the rental chains.
As usual all and any input welcomed.

It will be lighter and give a little more go but the trade off I'd higher ware ie won't last as long .
If you do go for one get a good brand .
I know the race guys normally go for the lighter chain but I can't see the benefits to fit one on a road bike
