34.9 Dropper Post Combo 80mm Travel with Internal Routing and Two Shim Adaptors

Adjustable Saddle Height for Your 34.9mm Frame

The 34.9 Dropper Post Combo pairs a 27.2mm internally routed dropper seatpost with two shim adaptors for a compatible 34.9mm frame. With 80mm of travel, you can lower your saddle for extra room on descents and raise it for seated pedalling.

From North Island bush tracks to South Island gravel routes, NZ rides often combine climbs with uneven descents. This combo provides adjustable saddle height for those changes in terrain, using a cable-operated sealed hydraulic mechanism.

Key Features

• Two shim adaptors supplied: Includes a 27.2 to 31.6mm shim and a slotted 31.8 to 34.9mm outer shim, used together to adapt the post for a 34.9mm frame.
• 80mm travel: Adjust saddle height for climbs, descents and rougher sections.
• Internal cable routing: The operating cable connects at the base of the post and runs through a compatible frame.
• Sealed hydraulic mechanism: Cable actuation controls the dropper mechanism.
• 7050 aluminium alloy post: Features a sandblasted black finish.
• Two-bolt saddle clamp: Suitable for round saddle rails and 7 × 9mm oval rails.
• Adjustable saddle angle: The saddle cradle adjusts from -5° to +18°.

Common Questions

• Q: Is the dropper post itself 34.9mm in diameter?
  A: No. The post measures 27.2mm. The two supplied shim adaptors allow it to fit a compatible 34.9mm frame.
• Q: Which shim adaptors are supplied?
  A: The combo includes a 27.2 to 31.6mm inner shim and a slotted 31.8 to 34.9mm outer shim. These are supplied for use together in this combo.
• Q: How does the 31.8mm outer shim fit over the 31.6mm inner shim?
  A: The outer shim has a slit that allows it to compress around the inner adaptor. This specific combination has been used together by the retailer.
• Q: Will this combo fit my bike?
  A: Your frame must accept a 34.9mm seatpost, permit this shim arrangement and support internal dropper cable routing. Check insertion depth, base actuator clearance 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 installation requirements for the frame, post and adaptors, including any greater minimum insertion requirement.
• Q: How much saddle adjustment does it provide?
  A: The post provides 80mm of travel and measures 370mm overall.
• Q: Is it cable-operated or hydraulic?
  A: A cable operates the sealed hydraulic mechanism. The cable connects at the bottom of the post and routes internally through the frame.
• Q: Which saddle rails fit the clamp?
  A: The clamp is listed as suitable for round rails and 7 × 9mm oval rails. Check your saddle manufacturer's clamp requirements before installation.
