"Crank arm holes pre-cut to width"

Includes everything needed to fit including:

3M tape x 2 - we recommend purchasing extra chainring guard tape if you have a power meter as you will need to remove the chainring guard to recharge. Shimano power meter cranks vary in battery life, however, the battery seems to last approximately 200-300 hours, check your battery life online for a more accurate time frame.
Carbon tape (Optional to go on crank arm opening if you choose)
