Choosing Crank Length

Left 4-position crank arm

Set your crank length to one of four positions.

Right 4-position crank arm

Crank length can be selected to correspond with an outdoor bike you own, or estimated based on height using the table below.

Length Height
165 mm Up to 5’6” / 168 cm
170 mm 5’6”-5’9” / 168-176 cm
172.5 mm 5’9”-6’ / 176-183 cm
175 mm 6’ and up / 183 cm and up

Once you have installed your pedals in your preferred position, open the Stages Cycling app to select the corresponding crank length under Crank length settings. Crank length can be updated at any point by removing the pedals and reinstalling them to a new position. The configuration must be updated in the app when the pedal position is changed.

Note: 172.5 mm is the default crank length in the Stages Cycling app.

Failure to set crank length properly will result in inaccurate power readings.
