Good things come in smaller packages. That's why PNW Components fit all the features of their Rainier Gen 3 into a slimmer, 27. 2mm package named the Rainier 27. 2 IR V3 Dropper Seatpost. This seatpost offers the most drop of any 27. 2 post on the market, and that ensures our rides can get as wild as we want them to get. It's easy to dial in and allows for a total of 25mm of travel reduction in 5mm increments. An updated cold weather-proof cartridge offers reliability in most conditions so we can keep riding through the rain and snow without worry.
