THE TRICK TO PAIR A ROTOR POWER METER
I see a lot more ROTOR Power Meters lately. From my experience, the new INPOWER and 2INPOWER work flawlessly. But, I have heard from many cyclists that they can’t get them paired to their head unit. So, here’s the trick to pair a ROTOR power meter.
Currently, ROTOR makes 2 Power Meters. INPOWER, which is a single sided power meter, and 2INPOWER, which is a dual-sided power meter. These power meters are offered only with a 30mm crank spindle. 
The reason is that more room is available inside a 30mm spindle than a BB86 (24mm) spindle. Inside the spindle is where ROTOR inserts the electronics.
But, for those that have a BB86 bottom bracket (example GIANT TCR ADVANCED), don’t worry, Wheels Manufacturing/Enduro Bearings makes bottom bracket bearings that will insert into your BB86 bb shell and allow you to run a 
BB30-type crank (SKU BB86-30-BB). See pictures.
So, back to the original concern … Why is it so hard to get the ROTOR power meter paired to a head unit? It’s actually very simple – if you know the trick.
With most crank based power meters, e.g. Stages, Pioneer, 4iiii (which are the ones I like best), all you do is spin the cranks to ‘wake-up’ the power meter(s).
Once ‘awake’ the head unit quickly finds the power meter and pairs. The ROTOR works a little differently. You need to apply an actual FORCE on the crank arm to wake-up the power meter(s).
So, the BEST way to pair the ROTOR to your head unit is to start riding your bicycle. After 10 seconds of applying a pedaling force, click PAIR on your head unit.
Note: It’s easiest if you already have your head set up. That way, you aren’t taking your eyes off the road for an extended amount of time. Just click PAIR and within a couple of seconds – SUCCESS!!!
