Have you tried Peter White for a seatpost? He got some from Nitto in 27. I'm not sure if he still has any but he got some of the Crystal Fellow S-65 seatposts which, although they aren't a two bolt seatpost, they are a true micro adjust seatpost. http://www.peterwhitecycles.com/seatposts.asp

There is also Ritchey Design whith 25mm of offset. http://www.amazon.com/dp/B003RLK3LU/...SIN=B003RLK3LU Unfortunately it doesn't look to be a microadjust. It has two bolts but not where they will help adjust.



I still believe the lacing may be making it too inflexible causing pain. I struggled with mine for a while too and found it was a tad too high, maybe a centimeter. That centimeter made all the difference in the world.
