All in one piece now. No dropper yet because my nephew has a bit of growing to do before he will get any benefit out of it as the seat height is approximately correct for his current leg length. I have ridden it around a bit and its a fun bike, super planted with the 280mm bb height.
Weather permitting he will be getting a nice surprise this weekend, though the forecast is currently looking terrible hahaha. So it might be a few weeks yet til handover day.
