Nice titanium seatpost for the price. Not as light as carbon but will hold up better in the long run. Used a 27.2 for a vintage build.
Loose saddle, not worth the money. I saw some reviews in other places about the clamp not having enough force to keep the saddle in place. I messaged the seller before buying the post to ask if this was true or if those folks had installed it wrong. I was assured they installed it incorrectly. After ordering the seatpost I messaged the seller again to ask for torque specs on the retainer bolt, and was told 5-7 Nm. This is not enough, and the clamp still gets loose and the saddle angles upward very uncomfortably after a few rides. Brand new saddle, brand new rails, still gets loose. Torqued it to 10Nm and added threadlocker, still angles upward. I am worried the bolt is going to break on a ride because I've had to overtighten it, which is the whole reason I moved to this kind of seatpost. I told the seller about the issue a month ago and was ignored. Not worth the money.
