Turnon Bunker 2.0 Dropper Post (Internal, No Remote) – 30.9mm, 125mm
SKU code: BPW-DSP001
The Turnon Bunker 2.0 is a cable-actuated, internally routed dropper post built around a patented double air chamber. The cartridge is fully sealed and self-lubricating, so the action stays smooth without stick-slip and the service interval stays long.
Highlights
- Double air chamber design (US patent 12054214B2) for a smooth, consistent stroke
- Fully sealed, self-lubricating internals with wiper seals against water and dust
- One-piece stanchion
- V2.0 head: 33mm stack height, with slide rail shims front and rear
- 125, 160 or 190mm travel in 30.9, 31.6 and 34.9mm diameters
- Travel can be shortened by up to 25mm with the Bunker travel adjust kit
- Comes with 1600mm housing and 1800mm inner wire; remote sold separately
Choosing a size
Measure from the top of the seat tube collar to the centre of your saddle rails at your normal riding height, then pick the longest travel whose minimum seat height (collar to rails, post fully inserted) fits under it, and check the frame takes the post's maximum insertion.
125mm: 372mm long, 214mm max insertion, 158-289mm seat height range. 160mm: 442mm long, 249mm max insertion, 193-347mm. 190mm: 510mm long, 287mm max insertion, 223-371mm.
Remote
The post is sold without a remote. Turnon's Bunker 1-By remote is matched to it, with a short 6mm cable pull. Any 1x-style dropper remote with a compatible pull will also work.
Fit
Internal (stealth) routing only, for frames with an internal dropper port. Choose the diameter your frame's seat tube takes: 30.9, 31.6 or 34.9mm.

Turnon dropper posts are covered against defects in materials and workmanship. Wear parts (wiper, seals, bushings and keys), damage from crashes, over-tightening the saddle clamp, fitting beyond the maximum insertion line and lack of servicing aren't covered.
For warranty support, return the item to Tune Cycles with your proof of purchase and we'll manage the claim with the distributor for you. This cover is in addition to your rights under the Australian Consumer Law.
