Convert your current crankset into a dual-sided 4iiii power meter!
The 4iiii PRECISION Dual-Sided Factory Install option allows you to convert your current crankset into a dual-sided 4iiii power meter. Offered in the PRECISION (CR2032) version, this factory install option is available for a variety of existing cranksets (full list below).

Please confirm your crank arm/bike has clearance for a crank arm power meter by checking your frame clearance. All sales are final. U.S. and Canada shipping addresses only.
Please note, due to the fact your crank gets sent to Canada and back, combined with currently slower install times at 4iiii, we are seeing turnaround times for factory install power meters of well over a month. Of course, there is nothing we can do to shorten this timing as we are never in possession of your crank, however we do like to make sure customers are aware of this before ordering.
