Which is exactly why I want to get rid of the suspension seatpost on my hybrid - it really makes it much less comfortable, and I find myself adjusting the seat height every few miles. After I've been riding for a while, my knees hurt because it's too low. So I raise it a bit, but now it's too high so my bum hurts, then it sinks so it's too low so my knees hurt...
Maybe this is just what happens with cheap suspension seat posts, a Thudbuster might be brilliant - but I'd rather go without.
