Drop the saddle out of the way at the push of a lever and get it back for the climb. The TranzX YSP39J is an internally routed dropper post with 200mm of travel in a 556mm-long post for 34.9mm seat tubes.

Highlights

  • Internal cable routing
  • 34.9mm diameter
  • 200mm travel
  • 556mm total length

Check the measurements

Before ordering a dropper, measure three things: your seat tube's inner diameter, how far a post can go into the frame (maximum insertion), and your saddle height. The post's total length has to fit inside the frame with the saddle at your riding height.

Compatibility & fit

Choose 34.9mm only if it matches your frame's seat tube, and check the frame has internal dropper routing. Compare the 556mm total length with your frame's maximum insertion and your saddle height. Fitting isn't included in the price, but our workshop can fit the post, route the cable and set up the remote lever.

Covered against defects in workmanship. Normal wear and tear, routine maintenance, improper installation or use, and modification are not covered. For warranty support, return the product to Tune Cycles and we'll manage the claim with KWT Imports, TranzX's Australian distributor.
