Step 4: Install power meter

  1. Before installation, remove the white band and plastic spacer from around the power meter.
    See our related Technical Service Bulletin: TSB 05122023 – Indoor Power Meter Battery Compartment.
  2. Line up the power meter (#10) onto the exposed splines of the bottom bracket, ensuring that the power meter is parallel to the user-right crank.
  3. Carefully begin to thread the power meter onto the bike. Using an 8 mm hex wrench, tighten to a minimum of 52-57 N⋅m until there is no visible gap between the crank arm and the bike.
