Discover the essential uses of grease in bike maintenance for smoother operation and extended longevity. Keep your bike in top condition with our tips.

We have already applied grease before sending out the bike. While it isn't necessary, you may want to apply some grease to the pedal threads and seat post during assembly. Rest assured, all essential components have been taken care of by FavoriteBikes

1. Bottom Bracket, Pedal, and Crank Threads

Applying grease to the threads of bottom brackets, pedals, and cranks is crucial. These parts have large diameters but fine threads, making them prone to wear and damage. Grease acts as a protective barrier, preventing metal-on-metal contact that can cause thread stripping. Additionally, it offers some waterproofing, helping to prevent rust and corrosion. Greasing these components also makes future removal and maintenance much easier.

2. Bottom Bracket Spindle

For bikes with traditional square taper or splined bottom brackets, applying grease to the spindle and the inner walls of the crank arm's opening is essential. This practice not only eases installation and removal but also reduces wear during pedaling, thereby extending the life of these components.

3. Brake and Shift Cables

If your bike's brake and shift cables lack a Teflon coating, applying a thin layer of grease can be beneficial. It ensures smoother operation, making gear shifts and braking more responsive. However, be cautious not to overapply, as too much grease can make the cables feel sticky. For cables with a Teflon coating, avoid using grease since it can negate the natural lubrication properties of the coating.

4. Ball Bearings

Maintaining ball bearings in the headset and hubs is critical for smooth bike operation. After thoroughly cleaning the bearings and the bearing cups, apply a generous amount of grease. This not only enhances the bearings' resistance to water and dirt but also ensures smoother rotation and prolongs their lifespan. For sealed bearing systems, applying grease to the outer surface can provide extra protection against moisture and minor impacts.

5. Seat Post and Seat Tube

When installing the seat post, it's advisable to apply grease to both the seat post and the inner walls of the seat tube. This prevents minor friction, protects against dust and water ingress, and reduces the likelihood of annoying creaking noises caused by debris trapped between the seat post and tube.

Final Note: Don't Use Grease on the Drivetrain ( Please refer to the article How to Clean an Ebike Chain – Favoritebikes)

While grease is beneficial for the applications mentioned above, it should never be used on the drivetrain, including the chain and cassette. These parts require specific liquid lubricants designed for optimal performance and protection. Grease can attract dirt and grime, leading to increased wear and decreased efficiency of the drivetrain components.
