I did buy a Fensport crank pulley, but they've messed me about multiple times now.
Besides, you single pulley actually looks better, although I'm more interested in the weight saving.
That said, for the price of it, it looks like worth a buy.

Is that the one you got? Would you say it's any lighter than the stock one?
I think I may have to copy you on that one to be fair!
