Very nice the new scalpel , reduced headset , lefty 2.0 , much lighter that the first , i think the position of the rear shock is different , rear brake inside the chainstays , for what i saw i presume that the rear is also assymetric , seat post is 27.2 mm , i saw only one cable in the down tube as fsi , and saw louckout of the rear shock , the frame seems to be much lighter and dont has all that curves that the actual has , as the fsi at distance it seems to be an 650 b but i think that is the new scalpel 29 er .
