Every Button on Your AXS Levers, Finally

If you ride SRAM AXS, BikeControl has been able to react to your shifter clicks for a while — but only in a limited way: every button looked the same to the app, so all of them had to share one action. After a lot of tinkering, BikeControl 6.3 changes that. Your AXS levers are now fully supported, with every individual button recognized on its own.

Left paddle, right paddle, the Bonus buttons on the hoods, wired Blips, even Vuka extension shifters — each one shows up in BikeControl by name, and each one can do its own thing.

Your setup is backed up — and restored on request

Out on the road, your derailleur is in charge: press a paddle, and it shifts. On the trainer you usually don't want that — the shifting should happen virtually, inside BikeControl or your trainer app, not on your physical drivetrain.

So when you set up SRAM control, BikeControl does two things:

1. It backs up your current AXS button configuration — the way your buttons are set up today, including any customization you made in SRAM's own app.
2. It then asks the derailleur to stop shifting on its own and simply report button presses to BikeControl instead.

Nothing is lost, and nothing is permanent: tap Restore original shifting at any time and BikeControl writes your backup right back to the derailleur — everything works exactly the way it did before, ready for your next outdoor ride.

Setting it up

You'll need BikeControl 6.3 and a charged AXS drivetrain. Roughly, it goes like this:

1. Wake up your drivetrain by tapping a shifter, then connect BikeControl to your SRAM derailleur — it appears in the device list like any other controller.
2. Tap Set up SRAM control.
3. Your derailleur will ask you to prove it's really you: press and hold the AXS button on the derailleur until its light flashes.
4. That's it — BikeControl pairs, backs up your configuration, and takes over. Every button on your levers now appears in the app, ready to map.

Not just shifting

Out of the box, the right paddle shifts up and the left paddle shifts down. But every button is freely assignable, so your levers can do a lot more than change gears:

• Shifting, of course — including switching the chainring of the virtual front derailleur introduced in 6.2
• Music & volume control — skip a song or turn it up without letting go of the bars
• Steering in supported trainer apps
• Screenshots and screen recording to capture that sprint finish
• Control a Wahoo KICKR Headwind fan, launch a shortcut or command, and much more

And here's the part that doubles the fun: double press is its own action. Each button can have one action for a single press and a different one for a double press — for example, single-press the right paddle to shift up, double-press it to skip to the next song.

Shimano Di2 — and welcome, WHEELTOP

Shimano Di2 riders already know all of this: Di2 has been well supported in BikeControl for a long time, with individual buttons, long press, and double press actions.

With 6.3 a new controller joins the family: WHEELTOP EDS shifters (OX and TX) are now supported in beta. The top and bottom buttons shift up and down by default, and — you guessed it — they're fully remappable. If you ride WHEELTOP, give it a try and let us know how it works for you via the in-app support chat.

On the app side: welcome, Strappo

Controllers aren't the only newcomers. Strappo is now an officially supported trainer app. Strappo lets you ride any real road on Earth — pick a route or import it from Strava, and it streams live 3D satellite imagery while your trainer matches the actual terrain.

Strappo speaks the open OpenBikeControl protocol natively, so BikeControl connects to it directly over your network or via Bluetooth — no keyboard emulation, no custom keymap. Pair your controller, pick Strappo as your trainer app, and your buttons just work.

Try it

Update to BikeControl 6.3, connect your levers, and enjoy having every button at your service — knowing your original setup is safely backed up and one tap away from being restored.

Happy riding! 🚴
