Dropper Posts

Answer 3 questions to find the perfect Dropper Posts for your bike!
1. What diameter seatpost does your frame use?
2. What type of cable routing do you need?
MTB are designed to accomodate a certain seatpost diameter.
  • Shims are available to put a smaller (e.g. 30.9mm) seatpost in a larger (e.g., 31.6mm) frame, but it's recommended to purchase the right one!
  • Remove your current seatpost to read the markings at the bottom
  • Or measure the diameter using this guide on What Dropper Post Fits your Bike.
  • Internally routed (stealth) droppers require a port for the cable to exit the frame, at the headtube (fully internal), or at the bottom of the seattube.
  • If your bike doesn't have these ports, you'll need an external dropper.
  • There are also wireless droppers and droppers with a lever under the seat that can be run without internal cable routing.
