Very annoying. I don't understand why people feel like it's okay to rip stuff off people's bikes. Or to rip off entire bikes, for that matter.

Glad you were able to find suitable replacements.

My Dahon is ALL about quick releases, and it would be a pain to replace the seat & seatpost, since it's a wide-diameter post with SDG I-Beam system. If I ever have to lock that bike up outside, I either take the seat with me or run a cable through the seat to my U-lock.
