i removed my heel shifter because i find it extremely awkward to use and will never use it..in a worst case scenario it could cause a problem if accidentally bumped, so its gone. i moved the toe shifter out i guess 3/4" or so to the outer position which feels better. Is there a spacer made by HD or someone else to fill the void?there is a black spacer i quess 1/4" thick thats been there, and an o -ring inbord of that which i aint sure why its there.
