30.9 Dropper Post Internal Routing 80mm Travel with Shim Adaptor

Adjustable Saddle Height for Your 30.9mm Frame

This 30.9 Dropper Post Internal Routing setup combines a 27.2mm dropper seatpost with a 27.2 to 30.9mm shim adaptor. It provides 80mm of saddle height adjustment for a compatible frame that accepts a 30.9mm seatpost and permits shim use. Lower your saddle for extra room on descents, then raise it for seated pedalling.

From North Island bush tracks to South Island gravel rides, changing terrain can call for a different saddle position. This internally routed setup gives NZ riders a practical way to adjust saddle height while keeping the operating cable routed through a compatible frame.

Common Questions

• Q: Is the dropper post itself 30.9mm in diameter?
  A: No. The post measures 27.2mm and comes with a 27.2 to 30.9mm shim adaptor for a compatible 30.9mm frame.
• Q: Will this setup fit my bike?
  A: Your frame must accept a 30.9mm seatpost, permit shim use and support internal dropper cable routing. Check insertion depth, clearance for the base actuator and cable, and your required saddle height before ordering.
• Q: What is the minimum insertion depth?
  A: The post requires at least 100mm of insertion. Follow the post, shim and frame installation requirements, including any greater minimum insertion depth.
• Q: How much saddle adjustment does it provide?
  A: The post provides 80mm of travel and has an overall length of 370mm.
• Q: Is it cable-operated or hydraulic?
  A: A cable operates the sealed hydraulic mechanism. The cable connects at the base of the post and routes internally through a compatible frame.
• Q: Which saddle rails fit the clamp?
  A: The two-bolt clamp is listed as suitable for round rails and 7 × 9mm oval rails. Check your saddle manufacturer's clamp requirements before fitting.
• Q: Can I use it on a gravel bike?
  A: Yes, if your frame accepts this post and shim arrangement and has suitable internal routing and clearance. Check remote compatibility with your handlebars, particularly if you use drop bars.
