We next come up to a source of squeakiness that I’ve decided to squash! My jockey wheels often result in my friends pointing and laughing at me as I squeak up a hill.
They are nearly 5 years old so it’s time for a replacement. If your jockey wheels are looking worn out by rust or their teeth have worn away then a replacement is easy. Most jockey wheels can be simply taken off, cleaned, greased and then put back on the bike.
- If the old jockey wheels are looking worn out then get yourself a pair of new jockey wheels. Note that the upper and lower jockey wheels are normally slightly different in size. You can use your existing pair of jockey wheels to work out which new ones you need. As my drivetrain is a Shimano and it’s a hybrid bike, I needed Shimano mountain bike jockey wheels.
- Grab some grease and an Allen Key.
- Get the chain off the bike using a quick release link or a chain tool if your chain doesn’t have a quick link.
- Choose which one of the two jockey wheels you will service first. It’s best to do them one at a time so as not to be confused as to which one goes where.
- Undo the bolt using an Allen key and clean the jockey wheel.
- Apply grease to the bolt, bushing sleeve and inside the pulley wheel.
- Put the jockey wheel back together and re-attach it to your bike. Making sure to firmly tighten it.
- Repeat with the other jockey wheel
- Re-attach the chain making sure to thread it over the top jockey wheel (it will currently be at the bottom height wise), under the top jockey wheel and finally up and over the lower jockey wheel.
- Re-attach the quick release link or push the chain pin back in using a chain tool.
