The BBInfinite PressFit bottom bracket (BB) module is a high-precision component designed to deliver smooth, long-lasting performance for cyclists using modern pressfit standards such as PF30A, BB90, or T47. The BBInfinite system is engineered for easy installation, durability, and ease of maintenance, making it a popular choice for both casual and professional riders. This guide provides a detailed walkthrough of the installation process, maintenance requirements, and troubleshooting advice based on information from the manufacturer’s documentation and user experiences. The following discussion will focus on the installation of the BBInfinite module, cable routing considerations, use of tools, and long-term care of the system.
Installation Process Overview
The BBInfinite installation process is designed to be user-friendly, provided the correct tools and techniques are used. According to the manufacturer, the press interface tools are included with the module purchase, and they are compatible with popular headset presses such as the Park Tools HHP-2 or HHP-1. These tools allow for accurate and safe installation without risking damage to the frame or the module itself.
One user noted that the installation instructions are graphic-heavy and easy to follow. Before beginning, it is recommended to clean the area of any dirt or grease to ensure a proper fit. Additionally, the non-drive side of the BB module is secured with a light-duty thread lock, while the drive side may already have some inside the frame. This step is important for maintaining the integrity of the installation and preventing future creaking or shifting issues.
For users without access to a headset press, it is strongly recommended to seek the services of a reputable bike shop. This is because improper installation methods, such as using a hammer and block of wood, can lead to misalignment or damage to the frame or the module. Doing it right the first time ensures a smooth, quiet bottom bracket for years to come.
Cable Routing and Liner Installation
A critical step in the installation of the BBInfinite module involves managing the derailleur cable routing. In some cases, the derailleur cable may interfere with the module, especially in frames with internal cable routing. A practical solution involves using a Teflon liner to prevent the cable from rubbing against the module.
To create a Teflon liner, users can strip the sheathing from a derailleur cable housing using a razor blade, then peel away the steel strands to reveal the Teflon material. This liner is then slid over the cable and positioned to prevent contact with the module. The liner is not strictly necessary for the system to function, but it helps prevent long-term wear and potential shifting issues caused by the cable rubbing against the module housing.
It is important to note that running a cable over a smooth, rigid object like the BBInfinite module is not the same as crossing cables inside the frame, which can lead to shifting problems. The BBInfinite module provides a stable surface, and with proper cable routing, there should be no interference or ghost shifting.
Installation Tips for Specific Issues
During the installation process, users may encounter specific issues that require troubleshooting. One such issue is the crank spindle not fitting into the bearings on the BBInfinite 30mm spindle module. This can occur if the spindle is slightly oversized, which is common with certain brands like FSA and Cannondale Si.
To resolve this, the manufacturer recommends using 800- to 1000-grit sandpaper to lightly polish any protruding areas on the spindle. Additionally, placing the spindle in the freezer for about an hour can cause it to contract slightly, making it easier to insert into the bearings. This method is both simple and effective, ensuring a secure fit without the need for more invasive modifications.
For users removing an existing pressfit bottom bracket, the process is relatively straightforward and does not require special tools. A standard headset press or a pressfit removal tool such as the Park Tools BBT-30.3 can be used. However, it is important to exercise caution when using such tools to avoid damaging the frame or the new BBInfinite module.
Maintenance and Long-Term Care
The BBInfinite module is designed for longevity, but like all bearing-based components, it requires regular maintenance to ensure optimal performance. The manufacturer recommends cleaning and re-greasing the bearings every 3,000 miles or more frequently if riding in extreme conditions such as cyclocross races or rainy multi-day mountain biking events.
The recommended lubricant is Kluber IsoFlex Topas NB52, which is specifically formulated for use with the bearings in the BBInfinite module. This grease helps protect against environmental contaminants and ensures smooth operation over time.
When bearings do show signs of wear, they can be replaced using common hand tools and an appropriate bearing press. The manufacturer provides a service video demonstrating the replacement process, which is described as fast and easy. Users are encouraged to watch the full video before attempting the replacement to ensure proper technique and avoid damaging the module.
In addition to user-level maintenance, the BBInfinite offers a Factory Refurbishment Program. This service allows users to send their modules or threaded cups back for professional servicing at no cost. The process involves sending the item to a designated address with a reference number marked on the package. Upon receipt, the item is restored to perfect working condition within 72 hours and returned via USPS First Class mail for U.S. customers. International customers will receive an invoice for shipping costs once the refurbishment is complete.
It is important to note that the refurbishment process does not address cosmetic issues such as nicks, scratches, or fading. The focus is solely on restoring the functional integrity of the module. If a necessary part is out of stock during the refurbishment, the customer will be notified via email.
Addressing Common Issues
One of the most frequently reported issues with pressfit bottom brackets is creaking, often caused by misalignment, improper installation, or wear. The BBInfinite module is designed to mitigate this problem by providing a precise fit and high-quality bearings that resist movement and vibration. However, users must ensure that the installation is done correctly and that all components are properly secured.
The manufacturer also notes that using the recommended retaining compound—such as VibraTite 530, Loctite 609, or Loctite 641—helps prevent loosening and creaking. These compounds are included with the BBInfinite module and are applied to both the non-drive and drive sides of the installation.
Another common issue is the interaction between the module and internal cable routing. As previously discussed, the use of a Teflon liner is strongly recommended to prevent long-term wear on the cable or the module housing. This is a proactive measure that helps avoid potential shifting issues down the road.
Compatibility and Tool Requirements
The BBInfinite module is compatible with a variety of pressfit standards, including PF30A, BB90, T47 internal and external, and BSA. This makes it a versatile option for a wide range of modern bicycles. The installation tools provided by the manufacturer are designed to work with these different standards, ensuring a secure and accurate fit.
For users unfamiliar with headset presses or pressfit tools, the manufacturer recommends seeking assistance from a qualified bike shop. This is especially important for those who lack the necessary equipment or experience. Proper installation is critical to the performance and longevity of the module.
In addition to the press interface tools, users may need to have basic tools such as a wrench or screwdriver on hand for final adjustments and cable routing. The installation instructions include step-by-step guidance on how to proceed with each of these steps, making it easier for users to complete the process without unnecessary complications.
