... oh, and workstand clamping... at home, I don't have a real workstand, I either work at floor level with a small bottom bracket stand or I have a hanging system to suspend bikes from my basement ceiling, using the top tube and sometimes handlebar/stem ... either way - with the #1 option, the seatpost and seattube is free for clamping, in the #2 option, there's enough slack in the cable to be able to clamp to the seat post, but not the seattube
