Can anyone tell me what, if any, are the differences between discs like this
  http://cgi.ebay.co.uk/ws/eBayISAPI.d...4628  922&rd=1  which have the round holes in the carrier, and those on my 2001 MY bike, which have "wedge-shaped" holes in the carrier. 
 Both appear to have a 6-bolt fixing pattern. 
 TIA.
