How do the new and old 105 gruppo compare?
How do the shimano 105 2011 (st-5700) gruppo compare to the 2010 105 (st-5600) gruppo? What type of improvements (besides for the fact that they look like dura-ace and ultegra) do they have?
The new 105′s have the shifter cables under the bar tape and are supposed to shift better.
