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
  • Item #PNW0016
