Current Projects chat and miscellany

"...I think a slot down the back and front is the way to go, that would allow easy seatpost removal and height adjustability. I'm wondering whether it's taking out too much material."

Years ago I had a seatpost like that, with a 2-3" oblong cutout on both sides. Never knew what it was for, but it must have been for this or something similar. Mind you, the bottom inch or so was intact, so you'd still have to loosen the cable in order to remove the seatpost. Then again, how often do you do that?
