for sale is a surly instigator 2.0.  Frame size is medium.  It is a 26 plus but I ran it 27.5.  Used it off and on.  I went on to 29 so getting rid of the frame.  It is a nice bike to ride on the trails or the gravel.  I will include the shimano chip for the rear dropouts if I can find it.  Also have the open dropouts that I can throw in.  also have the rear dropout 12x142 thru axle.  44mm headtube.  seatpost accepts 30.9mm.  4130 chromoly steel.
