Interlock: the ultimate solution for pressfit frames
Designed specifically for pressfit frames, our Interlock bottom bracket system offers the perfect combination of stability, stiffness and durability. But what makes our Interlock system so unique? In this article you will discover the advantages and features of this bottom bracket solution.
What is the CEMA Interlock System?
The CEMA Interlock bottom bracket system connects both sides of a pressfit bottom bracket inside the frame with a threaded connection. This ensures accurate bearing alignment, preventing unwanted movement and wear. The cups stay firmly in place, resulting in a stable, creak-free solution with efficient power transmission and longer component life.
Advantages of the CEMA Interlock System
1. Stable and crack-free solution
A common problem with pressfit systems is noise development due to friction between different components. The Interlock design prevents this problem because both sides of the pressfit bottom bracket are connected to each other, preventing them from moving independently of each other. Thanks to the Interlock system, you maintain a quiet and smooth riding experience even with pressfit bottom bracket systems.
2. Increased stiffness
Thanks to the internal threaded connection, the overall stiffness of the bottom bracket is increased, minimizing energy loss. This ensures that every pedal stroke is converted directly into forward power.
3. Perfect alignment of bearings
The threaded connection keeps the bearings perfectly aligned, reducing friction and increasing bearing life. This ensures a smooth and efficient pedaling motion.
4. Protection against water and dirt
Thanks to the closed design of the Interlock brackets, penetrating moisture from the inside of the frame is kept away from the bearings. This eliminates corrosion and damage caused by moisture from the inside. The double O-ring design on the pressfit fit prevents water from entering the frame while acting as a buffer between the frame and bottom bracket.
5. Interchangeable bearings for maximum flexibility
The bearings of our all our bottom brackets are easily replaceable, making upgrading or replacement possible without purchasing a completely new system.
In addition, all of our bottom brackets are available with a wide selection of bearing types:
- Stainless steel bearings: Ideal for riders seeking durability and reliability.
- SRC ceramic bearings: Offer lower friction and higher performance.
- SG3-coated ceramic bearings: The ultimate option for the most efficient and durable performance.
6. Easy mounting
Installing a CEMA Interlock bottom bracket is easy. Installation is quick and requires only basic tools.
