Tacx Flux 2 Smart compatibility

Tacx · Direct drive · Current

Quick answer

The Tacx Flux 2 Smart accepts 130 mm quick-release, 135 mm quick-release, 12 × 142 mm thru-axle and 12 × 148 mm Boost thru-axle, ships with a Shimano/SRAM HG (HyperGlide) freehub, and supports Shimano/SRAM HG (HyperGlide), SRAM XD Driver Body, SRAM XDR Driver Body and Campagnolo. No cassette is included — fit your own or buy a matching one.

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.
