Here are some great FAQs from PNW’s site!

What’s the difference between the Rainier Gen 3 and the Loam?

There are a few differences between the Rainier Gen 3 Dropper post and the Loam Dropper Post. The Loam Post has a shorter actuator and more machining on the stanchion both of which work to create a shorter overall post. This allows for more travel in a larger variety of bike frames. Another difference is the cartridge. With the Rainier, you get a sealed “set it and forget it” cartridge. The Loam has the advantage of an adjustable air cartridge, where you can customize your return rate.

What is the tool less travel adjust system?

This system allows you the maximum drop for your post size. We accomplish this through a notched bushing under the midcap collar so you can dial in a more tailored fit.

Weatherproof Sealed Air Cartridge

The Rainier Gen 3 rocks an updated cold weather proof cartridge – providing you unparalleled reliability across all sorts of trail conditions. Plus when it does come time to service it’s an easy no-mess process.
