Used X-Fusion Manic dropper post for mountain bikes. 34.9mm clamp diameter with a 150mm drop. Action is smooth but has gotten a little slower. Sometimes you have to sit back down on the dropper to get it to come back up. Still functions just fine. These are rebuildable - you can get a new air cartridge and install it yourself or have a shop do it. Only selling because I upgraded.
Comes with the dropper cable end barrel for install but not the remote lever or cable/housing.
