By tapping, I mean threading the d.o. -won't hurt it for another simplex install. *** The adj screw (flipped aound so the head contacts the frame) looks ok for a stop.*** Here is a pic of tire position with the simplex on it. With the hanger and SunT, the wheel sits farther up than shown. The wheels are the 27 origs. Tires-27 1 1/4 (32-630) It will never be sold-perhaps in a yard sale someday in the hopefully far far future. Other componenets have been changed, so it is no longer stock. Like the bike-would like better shifting. Have decided not to hack off the hanger. Not my intention to tic people off-it must have been done before-was looking for those opinions on how. BTW-thanks for the offer on the dr-but I'll sort this out.
