My seatpost of choice was and still is a Ergon CF3 Pro (aka Canyon VCLS 2.0) seatpost but I had an opportunity to test and compare it to Kinekt spring based suspension from Cirrus Cycles. As it turned out it was in some cases (like slow forest road with a lot of tree roots) more comfortable than my Ergon and in some cases (like fast gravel route) a liitle bit less. But to me the biggest drawback of this saddle (apart from its weight) is that you can definetely feel that it is based on springs (bounciness) and a occasionaly bootoming out issue (when you hit a big pothole). Now I am waiting for Cane Creek eeSilk to arrive for testing. This should be interesting
In a meantime you can read my full review of Kinekt 2.1 here:
