Thru-axle adapter
Type 1 vs Type 2 axle split: pre-Q4-2019 "Type 1" units use the separate 010-13143-00 / T2835 adapter kit for 12×142/148; later "Type 2" units mount the rider’s own thru-axle directly. The kits are NOT cross-compatible — replacement freehub bodies are also Type-1/Type-2 specific. The Flux 2 ships with the 142/148 adapters in the box.
