The TranzX YSI36 is an ultra-lightweight dropper made for XC, gravel and all-road riding, so you can drop the saddle for descents and tricky terrain without carrying much extra weight up the climbs. This version fits 31.6mm seat tubes and routes internally.

Highlights

  • Ultra-lightweight design for XC, gravel and all-road bikes
  • Internal cable routing
  • 31.6mm diameter, 120 to 200mm travel options
  • Supplied with a TranzX KL remote lever
  • Zero offset head
  • Sandblast black finish with a hard-anodised black shaft

Material matched to travel

TranzX builds the shorter 120mm post from lightweight 6066-T6 aluminium and the longer 150, 170 and 200mm posts from stronger 7075 aluminium, so each length gets the right balance of weight and strength.

Compatibility & fit

Choose 31.6mm only if it matches your frame's seat tube, and check the frame has internal dropper routing. Compare the total length with your frame's maximum insertion and your saddle height before choosing travel; TranzX doesn't publish insertion figures for the YSI36. Fitting isn't included in the price, but our workshop can fit the post, route the cable and set up the 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.
