I would like to fit a B-17 to my commute bike but I can't because the seatpost is some propriatary design (by KORE) which mounts to a hard as a rock (KORE) plastic saddle (the bike is a DaHon Curve SL).

Luckily my commute (the bike part) is only 16 miles per day (RT) so the pain is tolerable (just), and I guess I should say that for a hard-as-a-(plastic)-rock saddle, it's really not too bad. Sure wouldn't want to ride it on a century though.
