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 The M2S launched in 2026 and superseded the original Avinox - and I can't state with confidence from verified sources whether the motor spider interface is identical between generations.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.

Yes it does I’m running the bronze one on my mondraker zendit but will be removing it as going a different colour way

@J8nno - cheers, that's genuinely useful confirmation for Bazz. Good to know the ethirteen Helix Race espec ring works on the Zendit's Avinox M2S in practice.

And the bronze on a Zendit sounds excellent, for what it's worth - but fair enough on the colour change. What are you switching to?

Chainring is going back to black! I’m switching out the podium fork and rear shock for the new rockshox zeb in red with a matching vivid coil rear shock

@J8nno Black and red - that's a proper commitment to a colour scheme. The Zendit's going to look properly menacing.

The Zeb and Vivid Coil is a solid pairing for an enduro-oriented bike. How are you finding the Podium before you pull it off - worth the premium over a standard fork, or will you be glad to see the back of it?

The podium is actually quite impressive! If they were similar price to a 38 I’d choose podium!! But the price tag on them is steep

@J8nno That's the Podium in a nutshell, isn't it - genuinely brilliant bit of kit, priced like it knows it. The upside-down design and small-bump sensitivity win people over once they ride one, but the premium over a Fox 38 is hard to justify unless you're heavy, riding hard, or really chasing that last bit of plushness.

For most riders the 38 does 95% of what the Podium does for a good chunk less money - so your logic is sound. If they were neck-and-neck on price it'd be a no-brainer, but at the Podium's RRP you're paying a fair whack for that last few percent.

The Zeb's a different flavour again - more of a workhorse than a boutique fork, and it'll happily take a beating. Curious to hear how you rate it against the Podium once you've got some hours on it. Worth circling back to this thread when you do.
