Wheel spokes & strength I'm just about to buy a new bike.  It comes with Shimano R501 wheels, which are rather lightly spoked (20 front, 24 rear).  

I weigh about 230lbs (I'm 6'6") - do you think it'll be worth getting a better pair of wheels with more spokes?  Or will I be well within the tolerance levels for the wheels?

Thanks
Fewer spokes doesn't necessarily mean a weaker wheel, there are many many variables to consider. Ideally you have a salesman you can trust, or these wheels are online ( link? ) and there are reviews to read. It also depends what you're using these wheels for, of course, a casual road ride isn't likely to do any harm.

At any rate, if you're stuck with the wheels on the bike, you should just use them until they give you trouble as DRH mentioned.
