Programming – SRAM Technical Service FAQ

Is RED eTap software or firmware open source? Can I get into the code and tweak it to make it work with 10-speed or change the shift speed at different points in the rear derailleur’s sweep?

No. It is a closed system. The RED eTap is not programmable. See more

Can I set up the SRAM RED eTap 2x11 system to do sequential shifting?

No. The rider always controls the front derailleur. See more

Can I customize the shifter paddle or blip operation? E.g. have the left paddle shift up or connect two blips to one shifter and have each blip shift in a different direction?

No. It is a closed system. The RED eTap 2x11 system is not programmable. Note: SRAM AXS controllers that are paired to 11-speed SRAM Red eTap derailleurs will not be configurable in the AXS app See more

Will the blips only perform the same shifting operation as the shifter they are connected to for eTap 2x11?

Yes, just like a mechanical system. See more

Can I hold down the eTap 2x11 shift lever to do a rear multi-shift?

Yes. When you let go of the lever the derailleur stops. See more

Can I program the shift speed?

No. We’ve optimized RED eTap 2x11 for ideal shifting performance. See more

Can you program in automatic rear compensation shifts when making front chainring selections? i.e. shifting to the small ring and simultaneously shifting into a smaller rear cog?

No. The RED eTap 2x11 system is not programmable. See more

Will SRAM make periodic eTap 2x11 firmware updates?

There are no planned regular updates. See more

Does the eTap 2x11 front derailleur know where in the pedal stroke I am and time the shift accordingly for optimal shifting?

No. The derailleur is not intuitive, shifts happen mechanically when you activate the shifter. See more

Does SRAM make a head unit that is compatible with SRAM RED eTap?

No, SRAM does not make a compatible head unit at this time. See more

Can the SRAM RED eTap 2x11 components communicate with my iOS or Android device?

No, the system cannot communicate with smart devices at this time. See more

Can I record and display my gear selection on a head unit throughout different points in a ride?

The eTap system provides this information, but it is up to the head unit maker to capture and record it. SRAM does not make a compatible head unit at this time. See more

Can Quarq power meter data be combined with gear selection data using SRAM or Quarq software when using SRAM RED eTap 2x11?

No, not at this time. See more
