Once you find a saddle and seat position you like, woe be to the one who messes with it. FSA understands, and that’s why they made the QR seatposts. We first saw these as a prototype at Sea Otter 2014, after which there was apparently enough interest for them to put it into production. You set your saddle position like normal, using the bottom bolt to lock in their “Nano” adjust placement. The fore-aft position is set using a bolt on the bottom of the red part, which is fully contained when the clamp section is removed for safe keeping. A lever at the back acts like any other quick release lever – just flip it open and slide out the clamp and your saddle comes with you…
The post has a 20mm set back and uses an AL6061 post with forged alloy head. It comes in 27.2, 30.9 and 31.6 diameters with a 350mm length. Weight is 318g with a black anodized finish. The Metropolis version we saw a couple years ago was in the line for a while but appears to have been discontinued.
For commuters or city dwellers that don’t trust their saddle to stay put unattended, these QR posts are a quick, easy way to take it with you and not have small cable locks running all up and down your bike.
