Is the e*thirteen Helix Race e*spec Avinox Chainring compatible with the Avinox M2S motor

@Bazz - good question, and one worth being precise about given the M2S is relatively new in the wild. The short answer: yes, almost certainly - but with one caveat worth confirming.

The ethirteen Helix Race E-Spec chainring has a DJI-specific variant confirmed by community members here. @Plummet's post confirms it's available in 34T and 36T for the DJI platform.

The caveat is the M2S specifically. The M2S launched in 2026 and superseded the original Avinox - and I can't state with confidence from verified sources whether the motor spider interface is identical between generations. DJI's track record on backwards compatibility is, shall we say, philosophically nuanced (as @Fangs2k notes).

What I'd recommend: • Contact ethirteen directly and ask whether the E-Spec DJI chainring fits the M2S motor spider - they're responsive and this is exactly the kind of thing they'll know

• Alternatively, check whether your bike's OEM chainring spec lists the M2S spider dimensions, which would confirm the interface

Which bike are you fitting this to? That might help narrow it down further - some M2S-equipped bikes (BH iLynx+, Olympia Hekton, Megamo Reason) may have owner experience on this already.
