Pro-Tech BB386 Bottom Bracket Cups

The BB386 shell type is a specific standard for bottom brackets used in bicycles. It ensures compatibility between the bike frame and crankset, allowing for smooth pedal operation. Choosing a BB386 bottom bracket can enhance your bike's performance and stability, making it a great choice for serious cyclists.

The drive side cup is located on the right side of the bike and supports the crankset while handling the load from the chain and gears. The non drive side cup is on the left side and serves a similar purpose but does not bear the same load. Both cups are essential for the smooth functioning of your bike's pedals.

The sleeve connects and supports the drive side and non drive side cups within the bottom bracket. It ensures proper alignment and stability, which is crucial for the overall performance of your bike. A well-aligned bottom bracket can lead to better power transfer and a smoother ride.

"Claimed weight" refers to the weight of a product as stated by the manufacturer, in this case, 1.8 ounces (50 grams). For cyclists, lighter components can improve bike performance and handling. Knowing the claimed weight helps you make informed decisions about upgrading your bike for better speed and efficiency.

No, the BB386 bottom bracket is designed to fit specific bike frames that are compatible with this standard. It's important to check your bike's specifications to ensure that the BB386 will work with your frame and crankset for optimal performance.

Signs that you may need to replace these cups include unusual noises while pedaling, difficulty in pedaling, or visible wear and tear. Regular maintenance checks can help you identify issues early, ensuring your bike remains in top condition for a smooth ride.
