ThreadFit 30mm Bottom Bracket

A threaded bottom bracket is a crucial component that connects your bike's frame to the crankset (where the pedals attach). It is screwed into the frame, making it easier to replace and maintain. Many cyclists prefer it because it is known for being quiet and reliable, ensuring a smoother ride. If you value ease of maintenance and durability, a threaded bottom bracket is an excellent choice.

The 30mm crank arms refer to the diameter of the spindle that connects the crank arms to the bottom bracket. This specific size enhances the fit and performance of your bike, especially in mountain biking. The increased strength and stability provided by 30mm crank arms can lead to better power transfer and control during your rides, making them a great investment for serious cyclists.

A grease injection system allows you to easily add grease to the bearings of your bottom bracket without disassembling it or visiting a bike shop. This feature helps maintain smooth operation and prolongs the lifespan of your bottom bracket, ensuring that your bike performs at its best for longer periods. It’s a convenient way to keep your bike in top shape with minimal effort.

Steel bearings are essential components that reduce friction between moving parts, allowing them to spin smoothly. Made from durable steel, these bearings provide long-lasting performance, which is crucial for maintaining the efficiency of your bike. The fact that they are produced in-house ensures quality control, giving you confidence in their reliability and performance.

A fit kit is a collection of components or adapters that allow a bottom bracket to fit various shell widths or types. Depending on your bike frame, you may need a specific fit kit (fit kit 1, fit kit 2, or fit kit 3) to ensure compatibility. To determine which fit kit you need, check the specifications of your bike frame's bottom bracket shell width, and select the kit that matches your requirements for a perfect fit.

Yes, you can upgrade your current bottom bracket to one that features a grease injection system. This upgrade will enhance the maintenance of your bike, allowing for easier grease application and improved longevity of the bottom bracket. When selecting a new bottom bracket, ensure it is compatible with your bike's frame and crankset specifications for optimal performance.
