Fulcrum freehub body
Which freehub bodies a Fulcrum wheel takes and how to choose the right one for your cassette.
Available freehub bodies
- Shimano HG (9/10/11s)
- Campagnolo splined (9–12s)
- SRAM XDR (accepts XD with a 1.85 mm spacer)
- Shimano Micro Spline (disc only)
- Campagnolo N3W (disc only, with kit)
How to choose
Shimano/SRAM-HG road → HG; Campagnolo 9–12s → splined body; SRAM road 12s AXS → XDR; Campagnolo Ekar 13s → N3W (disc wheels only).
⚠️ Mind the model
The body DIAMETER matters: old 17 mm hubs → 30 mm bodies; 2022+ disc hubs → 33 mm bodies. Fitting the wrong diameter is the classic mistake. For Campagnolo 11/12s on N3W you need the AC21-N3W adapter.
