Thank you.
Actually it doesn't ride as hard as I thought it would.
Still comfortable, not hard at all but you do notice it the moment when the road is very bad, then again, on stock rims/tires you do as well but a little less.
I didn't notice any power reduction either but then, it was raining yesterday so can't compare (yet). Rims are lighter then stock so I don't think I would notice any.
