Really looking forward to some more pics.
Did you ever gave trouble with a slipping seatpost in your Dyna frame?
I have to use 'carbon prep' (gritty paste) to stop mine slipping.. I don't want to go too nuts with the pinch bolt pressure.
I've never had trouble - but I'm 5' 7 so short and light. I know of plenty of people who did have difficulty. when my frame was replaced under warranty in 1993- -they put the most awful bolt through the seat clamp to hold the seat in place. I see from later MT5 frame sets, there is a standard seat clamp wrapped around the top of the seat tube. I was looking at mine and there is enough seat tube sticking up over the top tube to get one on there if needed. If yours is slipping - why not fit a stanrard clamp around it.
BTW there is a new thread for Dynatech lovers at the link below..
