Hi,

Anybody who can throw an empty rear wheel on the scale. I am debating if should buy a fancy OZ rear wheel for my F4 race bike or I could settle with a cheaper f4i. The fancy bling bling OZ weighs 5,08kgs so if the difference isn't to big I think I will save some cash and go f4i.

Thanks

 

About 6kg for a standard f4i rear wheel if anybody else needs this info!

 

That's about 13.2 lbs for us goofy non-metric folk.

 

A 1kg (2.2lb) difference can be a really big difference depending where the weight is located. The number you should be interested when looking at rotating parts is mass moment of inertia. That being said, I don't know if that info is easy to find.

 

I think that piece of math is more that my head can understand!

I know I have lost a good deal of unsprung mass.

Rear wheel is 1 -1,5kg lighter
Cush drive is 600g lighter

Last think would be to change the rear brake disc to a lighter one, but I'm not sure my skill would benefit a couple of gram's more weight loss.
