I love my new suspension seat. Makes things a lot smoother..
I order the suspension post with the Double Spring Comfort Saddle for my wife bike. We live in the county with dirt roads. Out dirt roads are not always the smoothest. After installing the suspension post and the comfort saddle , her back quit hurting when we rode on the bikes
Works well for a little extra comfort riding on the gravel. A simple 5-minute install comes with 2 additional spacers. You can also adjust the travel tension on the bottom of the seat post if required.
