Having recently built a rather lovely singular osperey into a randonneur type bike I am having trouble witht he seatpost. It seems to slip under load, particularly when transporting beer home from the shop in the saddle bag. Any recommendations for a decent seatpost that will not slip and poke the saddle into my test icicles in a most unpleasant fashion? Currently using something not dissimilar to this

I assume you mean the post is slipping down, not the saddle itself moving. I had similar on my Bob Jackson (more info on the issue here http://danmitch.typepad.com/a_bike_build/2011/11/a-week-on.html ) and fixed it with some carbon seatpost spray. You could also try a grease such as Copperslip which I use on rails / seatpost normally.

Hope this helps - Dan
