350mm will work. They are a bit heavy but on these bikes it doesn't matter. Be aware that once you put in in the seat tube it will get scratched up, so you may not be able to return it. Also, you want to grease it a bit before installation.Thanks. I just ordered one from Amazon to test and see how it works. It is free return so I have ease of mind in case it doesn’t work for me.
ordered Kinect Bodyfloat. I ordered 350mm length which seems like to same length of my current seat post. Will this add a lot more weight to the bike?
