Sb20 stages bike

I still haven’t been able to use the SB20 with the SYSTM app. It will only show half my wattage or read zero. I tried pairing also the left and/or right crank and it just doesn’t work. Anyone having the same issue? Or even better anyone who has a solution?

Cheers martijn

Pairing to the left crank for power and cadence and to the bike for ERG control has worked for me.

Same here, left crank for power and cadence, bike for erg works great
