I just checked and the spacing is 14-16-18-21-24-27.
With a 50 & 46t chainrings, the incremental spacing on the rear freewheel or cassette should be about 20%. Consider finding a 13-15-18-21-24-32 freewheel. IRD makes this freewheel, it's available from Harris Cyclery.

The increment between the 50 & 46t chainring is 9%. The cog spacing should have double the increment that the chainrings have.

Run your gearing through the Sheldon Brown Gear Calculator: http://www.sheldonbrown.com/gears/
