One of the most notable design improvements of PRECISION 3 is the new ultra-slim design at 5.5mm thick, making it compatible for a larger range of bikes, especially late model bike that have wider chainstays. As always, we suggest that you check the clearance on your bike prior to ordering a powermeter. You can reference the below clearance check document:
Please note, that unlike the last generation powermeters, we cannot customize the install location of the PRECISION 3 powermeter on the crank arm. When check your bike for clearance, ensure that it 8mm allen wrench passes between your crank arm and frame through the entire zone indicated in the clearance check document. If you find that the 8mm allen does not fit through the entire zone, such as for bikes with BB mounted brakes, then a PRECISION Factory Install might be your best option.
