Amflow Spider Chainring Tool

What it is
A purpose‑built, CNC‑machined tool for removing and installing the chainring spider lockring on Amflow / DJI Avinox drive systems. It’s the exact interface you need to safely service or replace chainrings, access the drive unit, or perform routine maintenance—without resorting to improvised tools that risk damage.

Why it matters
Amflow’s removable spider and lockring design requires a precise, well‑fitting tool. This one accepts a ½‑inch ratchet or a 24 mm open‑end spanner, giving you the flexibility to use common workshop tools you already own. It’s right‑hand threaded, so disassembly is anti‑clockwise, matching the system’s design and helping prevent user error or stripped parts during removal.

Real‑world use case
Riders swapping chainrings—whether changing gearing for different terrain or replacing a worn ring—need reliable access to the spider. Community reports from Amflow users highlight that a proper tool is essential for chainring swaps and a smart spare to keep on hand, underscoring how this isn’t just convenient, it’s practically mandatory for maintenance.

Best for

• Owners of Amflow or DJI Avinox‑equipped bikes doing DIY maintenance.

• Workshop techs servicing these systems in the shop or on the road.

• Any rider who wants a compact, durable tool to avoid costly mistakes when touching the drivetrain.

Tip
Pair with a torque‑controlled ratchet and follow any manufacturer torque guidance when reinstalling—this tool gives you the correct mechanical interface; careful torque and cleanliness finish the job safely.
