Ohhh yes, much much more????
It's the same 9speed sprockets, just a little closer together! Just like 8 speed to 9 speed (before that we were missing shifting ramps etc and just had bent teeth to help the chain allong). Nothing revolutionaly in groupsets since HG chains and cassettes (unless you went rapid rise, which is awesome IMO), thats obvious as no one (campag, sram, shimano, or any of the other smaller groupset makers) has made a new design other than lighter/stronger/stiffer/more gears in the last 15 years.
It wont stop me buying up a 2010 crankset though when the racer ditch them 🙂
