if you want to reduce stackers,get some high riser bars,120x25° or similar,and leave 20mm of stackers on the steerer.
but dont count on my opinion only,everyone will tell you another story.i´m just advising what the geometry of the frame on your pic is telling me...
bb isnt very high,looks like +35mm or so.
why is that headangle so slack,is it the pic or just me?
