Wheel Problem
I have a Mavic Ksyrium Elite rear wheel on my bike. The wheel has about 800 mile on it. If you put the bike on a work-stand and pedal the crank too spin the back wheel; stop pedaling and coast, the crank (and pedals) keep turning. What could be wrong with the hub, any suggestions or ideas?

Maybe not anything. That test on the workstand doesn't really replicate what happens when you are riding.
How does it ride? If you coast while you're out riding does the chain go slack?

I did bring the wheel into a shop and they told me it's a new wheel give it time to break in. That is when the wheel had 400 miles on it. I spent good money on the set of wheels, what gives. Do you think this will affect the performance of the wheel? It could be in my head but it feels as if the wheel has some sort of resistance to it that I have never experienced, or I could be out of shape.

How much pressure is needed to keep the crank from spinning?
It could be that your bottom bracket is just so smooth that it just moves with the slightest force... and there is always a little force exerted during freewheeling. The clicking sound is the pawls overcoming the resistance.
Unless it forces the crank with a significant force, I wouldn't sweat it, since you should be pedaling most of the time anyway.
In fact, I believe Sheldon Brown's reasoning to not service freewheel bearings was based on the facts that first, it was difficult to do, and second that you rarely coast, so they are the least used bearings on a bicycle.

With a new wheel, this could also be due to the rubber seals in the freehub that's dragging it along. Don't worry about it, it'll wear in over time.
