lol at JJ
The standard crank pulley weighs 2.5kgs
This weighs 550 grams so saves 2kgs over standard in rotating mass so should accelerate better. I am not sure whether I will be able to notice it but every little helps
I have now changed it having fought to undo the crank bolt .. the fekker :x so will give it a run out later on.
edit... I have just weighed the std pulley and it is 3 kilos

so a 2.5 kilo saving
