Why We Like The Rainier 27.2 IR V3 Dropper Seatpost

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.

Smooth and so easy

I've used it several times
5' 8"

Bought this for bike #3, a neglected 2016 Epic rebuild that I just picked up. I've got a Bike Yoke and Fox Transfer on the other two bikes, and this thing feels really on par so far. I paired it with the Loam lever - solid choice there, too. A breeze to install and the adjustability is genius. Great solution and brings an old bike with a 27.2 seat post up to speed with a respectable amount of drop (for the genre). Recommend!
