If it's the seatpost clamp you are talking about...I had this problem before....go pick up a seatpost clamp without a quick-release (I assume the Outlook still has a QR seatpost clamp...my old 2003 model did).

Most QR clamps don't compare to the clamping power of a properly made non-QR clamp. You should be able to go back to the bike shop you bought it from and get a really nice one for under $10. The best ones have a rotating threaded stud that the threaded part of the bolt goes into...this reduces stress on the bolt, which will allow for easier adjustment.
