Qalvin Legacy


Indispensable for bike shops, race mechanics or anyone seeking enhanced information from their power meter. Qalvin Legacy is for previous generation power meters that have ANT+ (only).



Qalvin Legacy, available for Windows and Mac, delivers firmware updates, diagnostics, power meter zeroing and calibration for previous generation power meters that have ANT+ (and not Bluetooth low energy technology).

Features & Benefits

  • For previous generation power meters that have ANT+.  For DZero and DZero DUB, use SRAM AXS App.
  • The fastest way to confirm operation at installation time — instantly on and easy to pair.
  • Update power meter firmware (models with CR2032 batteries only)
  • Check battery voltage.
  • Set zero offsets on multiple bikes quickly and easily.
  • Run advanced diagnostics to check power meter health.
  • Change the power meter’s slope using the built-in calibration routines.

Essential Details

  • Qalvin Legacy requires an ANTUSB2 or ANTUSB-m stick. Most ANT+™ USB sticks that come with Garmin fitness watches are compatible.
  • Qalvin and the Garmin ANT Agent™ cannot use an ANT+ USB stick at the same time. Close one program to use the other.
  • Previous generation power meters include Quarq CinQo, CinQo Saturn, Saturn2 and Quattro, SRAM S975, SRAM S2275, Quarq ELSA (all models), Quarq RIKEN (all models) and SRAM RED (not DZero).
