I've been looking at getting a remote operated adjustable seatpost and my choices have been narrowed down to the Gravity Dropper as it seems to be the only one that comes in a 27.2 mm diameter standard size... Thought that made my choice easy and I was going to get the multi drop 4" version, but now I see there is a Gravity Dropper Classic and a Gravity Dropper Turbo.... What's the difference between them apart from the price?

Anyone know?
