Guys and Girls !! there seems to be large amounts of wheel threads so sorry to add another.

does anyone know the differences ( if any ) between the old 7850 CL24 wheels and the new 2011 7900 CL24 model ??

on sight they appear the same however front hub is a different shape / square shape. it also appears from few retailers they are a bit lighter ?

i am asuming it is the same wheel albeit slight change of graphics and reworked hubs ?

the shimano website does not seem to be hlepful and does not list the new 7900 ( or at least i cannot find them

any help appreciated, cheers
