How to Replace the Crank Arm on a Peloton?

Peloton bikes are renowned for their sturdy construction and silky smooth ride, but even the most meticulously made machines will eventually show signs of wear and tear over time. The crank arm is one of the components that can need to be replaced. The crank arm is the component of the bicycle that links the pedals to the drivetrain and is responsible for transmitting the power from the rider’s legs to the wheels. If you are having problems with the crank arm on your Peloton, it is possible that you need to get a new one. In the following paragraphs, we will walk you through the steps necessary to change out the crank arm on your Peloton bike.

How to Replace the Crank Arm on a Peloton

1.      Determine the Nature of the Problem

It is essential to determine the problem first before beginning the process of replacing the crank arm. The following are some indications that your crank arm may have a problem:

  • Noises that sound like grinding or clicking coming from the crank arm
  • While riding, the bicycle has a shaky or unsteady sensation about it.
  • It is difficult to maneuver the pedals.
  • The performance of the bike is slow or inconsistent.
  • If you are experiencing any of these symptoms, it is quite probable that you will need to replace the crank arm on your bicycle.

2.      Collect All of the Required Equipment

The following items will be required for you to replace the crank arm on your Peloton bike:

  • Puller for crank arms
  • Allen wrench set
  • Torque wrench (tool)
  • Paper towel or rag for removing grease

3.      Remove the Original Crank Arm

The removal of the existing crank arm is the first stage in the process of installing a new one. Proceed in the following manner:

  • With the use of an Allen wrench, disengage the pedal from the crank arm.
  • To remove the crank arm from the bike, you will need to use a tool called a crank arm puller. Put the puller into the crank arm, then rotate it in the opposite direction of the clock until the arm can be removed.
  • Remove any dirt or debris from the crank spindle by wiping it down with a cloth or a piece of paper towel.

4.      Installing the Replacement Crank Arm

When the previous crank arm has been taken off, it is time to put the new one in place. Proceed in the following manner:

  • The crank spindle should have a very modest quantity of lubricant applied to it.
  • Put the replacement crank arm on the spindle by sliding it on, ensuring sure that it is oriented in the right way. Use a torque wrench to ensure that the bolt is tightened to the required torque standard given by the manufacturer.
  • With an Allen wrench, reattach the pedal to the new crank arm so that it turns.

5.      Put the Bike Through Its Paces

It is critical to put the bicycle through a series of tests immediately after the replacement crank arm has been attached to ensure that everything is operating as it should. Test the bike on a short ride while paying special attention to how it feels and how well it performs. It may be said that the replacement was successful if there are no problems.


Can I change the crank arm by myself?

While riding my Peloton, how frequently should I consider replacing the crank arm?

A. The intervals between crank arm replacements vary based on how the machine is used and how well it is maintained. On the other hand, if you are having problems with your bicycle, it is a good idea to check the crank arm to see if it shows any symptoms of corrosion or wear.
