Rainier IR V3 Dropper Seatpost

The Rainer dropper post has earned a solid reputation for consistent, reliable performance, so rather than changing the formula entirely PNW opts for some minor refinements that make this third-generation the best one yet. Travel is increased, and the travel is now adjustable in 5mm increments so you can fine-tune the fit if your ideal travel is somewhere between 170 and 200mm. At the same time, the post's total length is shortened, which is always a good thing—especially for bikes with interrupted or shortened seat tubes.

  • Reliable, affordable dropper with a wide range of travel options
  • Tool-less travel adjust for dialing in the perfect fit
  • Shortened total length fits a wider range of bikes
  • Sealed air cartridge offers smooth actuation
  • Constructed from lightweight but tough 7075 aluminum
  • Backed by a 3-year warranty for good measure
  • Remote sold separately

200mm travel with the bachelor post - which is very similar to the rainier - video shows the simple install of the PNW internal routed dropper posts

I purchased the Gen 3 200mm dropper and love it. Have been using it almost daily for one month. Love the 5mm increment easy adjustability. That alone is reason to purchase. Should be an industry standard.
