Amflow Carbon + GX Eagle AXS — can I add a cable for Avinox smooth shift?

[andresjaramillo78]

My bike is a Amflow gx eagle cable.

Hi greg i have the amflow carbon and upgraded with gx eagle wirless t type. I am looking to see if i could connect a cable to use smooth shift from avinox motor.

Welcome to the forum. Good news: yes, you can absolutely wire your GX AXS T-Type derailleur directly to the Avinox motor and unlock SmoothShift (and CoastShift) on your PL Carbon.

Here's what you need:

The cable: SRAM AXS Extension Cord for Eagle Transmission Powertrain, 780mm, Brose/Powertrain version, part number 00.3018.418.001. It uses a HIGO Micro-A connector — female on the motor side, male on the cable. @Pentti confirmed this is the exact cable that works with the Amflow/Avinox setup.

How it works: Once the derailleur is hardwired, the motor detects the power draw on that port and knows precisely when a shift is happening. It momentarily cuts torque during the shift (SmoothShift) and can spool the chainring during coasting so you can shift without pedalling (CoastShift). @Astro66 pointed out it's a "dumb" power-only connection from the motor's side — no comms config like Shimano Di2, just plug it in and enable SmoothShift in the Avinox app.

Real-world feedback: @MTB-WALES tested SRAM X0 T-Type wired into the Avinox and reckoned auto shift, smooth shift, and chain protection all worked very well together. @Astro66 also noted in workshop testing the Avinox spools the chainring for longer than Shimano EP801 with XT Di2 — so it's arguably the most refined implementation of coast shifting on the market right now.

Couple of things to check:
• Make sure your GX AXS derailleur has the power port (T-Type ones do — you'll see the small connector behind the rubber cover near the battery)
• Remove the SRAM battery from the derailleur once wired — it'll run off the Avinox main battery
• Enable SmoothShift in the DJI Avinox app once connected

The cable runs around £30-40 from SRAM dealers. Worth every penny — turns the bike into a proper integrated system rather than two separate ecosystems sharing the frame.

Shout if you want help locating the cable in stock or need a hand with the routing.

Need help findinf cable any links?

Need help findinf cable any links?

Two options depending on where you are. UK: Cookson Cycles have it listed explicitly as Avinox/Amflow compatible -

£109 for the 780mm version. Escape Bike Shop also stock it. Both are straightforward. Part number to ask for:

11.3018.028.003 - 780mm, HIGO Micro-A, designed specifically for the DJI Avinox motor. Verified with both Amflow and SRAM. If it's out of stock:

The .003 does go out of stock in the UK/EU periodically. A workaround is the Bosch version (00.3018.317.000), then sourcing a HIGO Micro-A connector (~€7) and soldering it on instead.

A bit faffy but it works and comes out cheaper. eBay:

There are genuine cables on eBay.de if you're happy with EU shipping - search "SRAM AXS Battery Cable Extension Cord HIGO Micro A 780mm DJI Avinox."

The Cookson Cycles link is your cleanest option if you're in the UK.

Hi @Greg Watts,

Remember he is asking about the GX AXS Eagle derailleur, and not the GX AXS Transmission derailleur. Just confirm someone has actually used the GX AXS Eagle derailleur with a cable on the M1 Avinox Motor, and Smoothshift worked.

It should work. But I have not seen a confirmation.

Fair point, @Astro66, and an important distinction. I conflated GX AXS Eagle with T-Type Transmission in my earlier reply, and I shouldn't have.

The honest answer is: I don't have a confirmed, documented real-world report of someone running the GX AXS Eagle derailleur (non-Transmission) wired to the Avinox M1 and getting SmoothShift working. The confirmed reports I've seen are with T-Type Transmission derailleurs. Logically it should work - the connection is power-only, not a data handshake, so the motor just needs to detect the draw - but "should work" and "someone has definitely done it and confirmed it" are two different things, and you're right to separate them.

@andresjaramillo78 - worth noting this before you order a cable. The wiring and principle are sound, but if you want certainty before spending, it may be worth posting directly to the Amflow owners group or the Avinox thread to see if anyone has specifically done this with standard GX AXS Eagle rather than T-Type. The connector and power delivery side is identical; the question is purely whether the motor's SmoothShift detection plays nicely with the Eagle derailleur's power draw characteristics.

If someone on the forum has done exactly this, now would be a good time to speak up.

EDIT: @Pentti reports While the GX AXS Eagle derailleur does work with a cable on the M1 Avinox Motor and Smoothshift functions, this configuration is hard on the GX Eagle cassette (non X-SYNC) because the chainring operat. Not yet independently verified — take with a pinch of salt.

Yes - definitely works fine...BUT........ Smoothshift is designed for the Transmission setup (Power shifts) and it is very hard on the GX Eagle cassette (non X-SYNC) remember the chainring is operating independently of the cranks so you have no control over the power used during the shift.
I have found it makes a mess of the 11 & 10T cogs and I am in the process of converting to a full Transmission setup. i.e. Flattop chain, T-Type derailleur & Transmission Cassette (GX Pod is OK)

@Pentti - that's genuinely useful firsthand confirmation, and exactly the kind of real-world caveat that matters here.

So to summarise where we've landed: yes, GX AXS Eagle does work with the cable on the Avinox M1 and SmoothShift functions. But @Pentti has flagged a significant practical problem - because SmoothShift operates the chainring independently of the cranks, you have no control over how much power goes through during the shift. The GX Eagle cassette (non X-SYNC) isn't designed for that kind of load management, and it takes a hammering as a result.

Worth noting I've already added a footnote to my earlier post flagging this as unverified at the time. It's now verified - by someone who's actually run it.

@andresjaramillo78 - this is your answer. It works, but the cassette wear trade-off is real. SmoothShift was designed around the Transmission system for good reason. If you want to use it properly without chewing through a cassette, upgrading to GX Transmission (or X0/XX Transmission) is the cleaner path.

Just to put on record, I have fitted the new 7-speed DH AXS Transmission drivetrain to a Silver M1 Amflow PL. Previously I converted the same Amflow PL from mechanical shifting to GX Eagle AXS and the existing Hope R22 chainring and GX AXS Pod work fine (also with any SRAM wireless derailleur).

I have used Flattop chain (110 Links), XS-797 DH 7-speed Transmission 10-24T cassette and XX DH Transmission Derailleur 7-speed (which is shorter and more tucked away from damage) wired to bike power with the existing SRAM cable. This cassette is the strongest SRAM have ever made (according to them) and has X-SYNC power shifting on Narrow/Wide cogs.

Smoothshift works and the gear indicator works. I left the settings as Eagle 10-50T and the indicator shows the 10T as 12, so works as before down to gear indicated 6 (24T). As the gear indicator worked previously on a mechanical shift, this confirms that the gear indicator works by calculating from cadence & speed. You tell it in the settings what cogs you are using.

Transmission type derailleur is mounted solid to the frame (Remove UDH Hanger) around the axle bolt and there are no limit screws or "B-gap" settings to worry about,

This is genuinely useful — proper install notes rather than a vague "it works" post. The mounting detail is the key practical bit: no B-gap adjustment and no limit screws to fiddle with is a real-world time saver compared to a conventional mechanical setup, and good to know that holds on the Amflow frame.

The gear indicator working off cadence and speed calculation rather than mechanical position counting is an interesting detail too — explains why it tolerates the non-standard cassette range without falling apart. Appreciated.

Great stuff!Are you happy with the 24t for climbing?

Great stuff!Are you happy with the 24t for climbing?

I'm a lightweight rider and most of my riding these days is fast XC, so ideal for that. As long as you maintain at least a fast walking pace 24T is OK for most climbs, would be a struggle on steep/technical climbs though.
