Hi Tom
If you bring your seat (or the whole bike) tonight to thursday nite "gearheads", as offered before, I can show you the considerations that will allow the seat to fit properly.. bent or unbent frame loop, good, bad or incorrect seat pan for your 850 frame, along with the correct seat buffers. will make the seat "fit".
