Gear indicator no longer showing on Avinox display

[RickBullotta]

I have the latest Avinox firmware and the latest SRAM firmware for the derailleur. This is on an Amflow PL Pro. It used to work.

Any suggestions?

It only shows if you have a Power Mode Selected. So no display if Assist is set to off.

It works by comparing the Cadence to the Wheel Speed. So on the Avinox display in settings, you must have the chainring size selected correctly, and the cassette size selected correctly.

If this is all set correctly. You just rotate the cranks a few turns with Assist on, and the gear selected should appear.

Thanks! For some reason I thought it communicated with the derailleur to get that. Good to know.

Nope. It's purely a calculation based on the ratio between crank revolutions and the wheel speed sensor. That's why it must know the chainring and cassette size, and you must rotate the cranks, to perform the calculation.

i never asked myself which gear i‘m in. why is that important?

 

[Astro66]

I've been descending and as I'm not pedalling, I've lost track of which gear I was in. Also descending with coastshift, I've pressed the shift button 2 or 3 times quickly, and sometimes you are not sure how many gears it shifted. So I just visually check the display, rather than pedal and check.

Also when you stop sometimes and then you take off, you are not sure which gear you are in, so you just check before taking off. It lets you know how much resistance you are going to get before you start.

You can get by without it. But sometimes it does help.

If you still have time to check the tiny gear indicator whilst you’re going downhill, you either have eagle eyes or you’re simply riding too slowly.
The gear indicator is just a simple tiny gadget, not more...

From what you say how it worked earlier in the thread, don’t you have to pedal anyway for it to update or does it remember where you started and then know whether you’ve shifted up or down?

I also find it useful as I do ride alpine trails and not park, I do encounter a lot of up and downs so when transitioning from downhill or flat to uphill I take a quick look at what gear I'm in and I do the right amount of down shift, with the AXS that can shifts without pedaling is just perfect, so by the time I attack the uphill section I'm ready. This also avoid me to change gear under heavy load uphill.

A second use case, as Astro66 mentioned, is when I stop especially on steep terrain I can make sure to be in 1st for restart without looking down to the cassette. Not gonna be able to start in 2nd... If I'm in not in 1st, I lift the back wheel and press the pod the right number of times.

A third use case I have a custom display that shows watts (mine and motor), cadence, gear and heart rate and I find it useful for optimize my effort vs battery.

If I could only pick two things to show on the display it would be battery % and gear.

It remembers the last one that was engaged (either by pedaling or by the smooth shift)

 

[sethimus]

ok that was the old, not used to smooth shift (yet) brain talking, from that perspective it makes sense

Yes. I descend calmly. I climb fast. I have had like zero serious injuries when mountain biking. I wish to keep it that way.

That said. Descending too slowly can also be dangerous, as you need momentum to climb over obstacles. Descending too slowly can cause the front wheel to not roll over an obstacle and pointing downhill, it can throw you OTHBs. So it's a balance.

But it's also why I really want to know what gear I'm in. If I need to clear an obstacle with a pedal stroke, I want to be in the right gear. Smoothshift and the indicator allows me to get this correct, before taking the pedal stroke.

So it happens this way. I'm descending. I see the obstacle ahead or a preferred line that has an obstacle. I glance down. I see I'm two gears too high. I press down twice. Then just before the obstacle I perform the power stroke, knowing I'm in the correct gear.

Ha - same with one exception: I was doing setup (reset) on a transmission derailleur and it would have been helpful because the AXS app kept disconnecting.

If you're referring to it simply not showing on the display anymore in some screen configurations you can tap on a data point to toggle between 2. Like tap the time and it'll change to gear, or battery percentage changes to distance. I do this inadvertently sometimes and confuse the hell out of myself.

My favorite screen (on my Levo but that's irrelevant here) shows heart rate; and the gear I'm using. To me it's simply the 21st Century version of looking back at the cassette to see what gear I'm in like I did back in the day. In practice I find it nice to confirm I'm in the gear I want to use on a known section of trail. I also have used it to monitor my progress. I used to climb the switchbacks on the main Hawes climb in 4th, now im doing it in 5th, or even 6th on a strong day. I wouldn't say I NEED this information but I do find it nice to have.

 

[Astro66]

There's some stairs locally that I climb in either 3rd, 4th or 5th gear, depending on the stairs gradient and length. It's nice to quickly confirm which gear I'm in before starting the stair climb. It's hard to be exactly sure whether I'm in 2nd, 3rd or 4th by feel alone sometimes. I'd probably get it right 95% of the time without the indicator. But with the indicator. It's 100% of the time.

And it's not just about torque. It's also some stairs need the cranks to be in the correct "Bottom Dead Centre", at the right time, when trying to avoid pedal strikes. And having the correct gear changes where "BDC" will be as you climb. Pedal striking climbing stairs can be quite nasty. Especially as I'm clipped in. It can pop a clip and you stall and fall over. Which on concrete stairs is very unpleasant.

Once again. Not a must. But a nice to confirm quickly and easily.
