Moots Titanium Cinch Seatpost. 27.2 x 340mm. This is their inline seatpost, which technically has 5mm of offset. Simple to install, independent tilt adjustment, independent fore/aft adjustment, clean solid design.

Welded construction for superior strength to weight ratio. 3/2.5 CWSR tubing drawn to exact size for better strength than ground or turned tubing.

Used for less than 1500km before I changed it out for a Moots seatpost with a larger offset. See photos for wear marks below frame insertion.
