Will 10 speed cranks work with an 8 speed freewheel? I'm looking at building a road-bike, and I've just purchased some wheels with campagnolo hubs, with an 8 speed freewheel on the back.

Can I use Campagnolo Daytona / Veloce cranks on the front? I understand that they state 10 speed on the cogs, but can I use them with my 8 speed on the rear?
According to Sheldon Brown's website:


  New Chainrings, Old Chains
  Going the other direction, using wider chains with chainrings intended for narrower chains is not generally a major problem if there's only a one- or two- generation difference. The only problem you might run into is that the chain will be more liable to rub on the inside of the bigger chainrings in the small/small crossover gears, gears you shouldn't be using in any case.


You may run into some poor shifting performance, but the system should still function.  If you are unhappy with the performance, 8 speed chainrings will mount on your current crankset, so there's no need to change-up everything.
