I would like to get a 30.8 setback seatpost for my NRS but it cannot find any. I don't want to get the 30.9 because I just called Giant customer service and they informed me that although the 30.9 will go in, it is not recommended for the seat tube as it might cause damage in the long run. I was thinking about the 30.8 thomson zero offset seatpost but I am 5'9" on a 16.5 inch NRS and thus, would like to have the setback for more room. Please advise and thanks!
I can only find 1 30.8 setback seatpost at Nashbar (please see below link). Although I believe Kalloy also makes one, I can find any place that carries them. Any other suggestions? Opinions on the Nashbar seatpost? Thanks.
Dirt Devil, how was the fit of the 30.9 on your seat tube, "snug" or "went in with ease". I asksed because I have gone through many of the old discussions and the response was either poistive or "the 30.9 post would fit but it requires twisting for it to go in". I am a little worry because I have called Giant Service and they told me that 30.9 would go it but it is not advised as it might over stretch the seat tube and damage it in the long run. Please advise. Thanks.
Snug will be a good adjetive for how it fits, mine went in without much "twisting".
That topic has been beaten to death here but kinda remained in the air. At that time James@Giant posted and if not mistaken he said that a 30.9 will not void any warranties, James is no longer with Giant so is up to each of us to believe what he said or not.
If you want to go in the safe side order a Thomson 30.8 and ride the heck out of the bike and rest assured that your frame will be warrantied.

yeah, I've got a Thomson 30.9 (no setback) on my NRS, and it fits fine, slightly snug, but not bad at all, there is no forcing it in or anything. I know Thomson makes a setback version too, but they are relatively pricey, not sure what your budget is, but I would highly recommend one.
