The Dune R isn't specifically in my database for dropper details, but the Dune range shares the same frame so the community knowledge carries over.
The main thing worth knowing: @Bogdan_CH measured the stock 180mm dropper on a Crafty with 60mm of exposed collar, and the Avinox/DJI platform bikes have a reputation for short seatpost insertion depths making long droppers tricky to fit. The Dune uses Bosch SX rather than Avinox, so that particular headache probably doesn't apply, but it's worth checking your minimum insertion mark before ordering anything ambitious.
What's your inseam? That'll determine whether the stock dropper is adequate or whether it's worth looking at a 200mm+ replacement. The SRAM calculator is worth a run if you're sizing up an upgrade.
