Product Information
Full details
The Truvativ Powerspline Bottom Bracket (BBTPS100) is designed for cyclists and bike mechanics working on road or trekking setups who require a durable and reliable interface for Truvativ 12-spline cranksets. This component delivers consistent performance through its heat-treated chromoly spindle and sealed cartridge bearings, though users should note it is exclusively compatible with specific Truvativ 12-spline systems rather than standard square-taper or external bearing cranks.

Extended Product Information
FAQs
Is this bottom bracket compatible with square-taper cranks?
No, the Powerspline uses a 12-spline interface and is not compatible with square-taper cranksets.
What tools do I need for installation?
You will need a standard 12-spline bottom bracket tool designed for cartridge bottom brackets.
Does this bottom bracket require regular lubrication?
The cartridge bearings are sealed and do not require external lubrication or servicing.
Can this be used on a mountain bike?
While intended for road and trekking, it can be used on MTB builds that utilize compatible Truvativ 12-spline cranksets.
What is the weight of the BBTPS100?
The unit weighs approximately 340g.
Is the chainline adjustable?
The bottom bracket features a fixed chainline control stop; chainline adjustments are typically managed by the crankset setup.
Troubleshooting
Creaking sound while pedaling
Verify that the crank bolts are torqued to manufacturer specifications and ensure the bottom bracket cups are fully seated.
Noticeable play or wobble in the crankset
Check if the splines are stripped or if the internal cartridge bearings have developed wear; if there is physical movement in the spindle, replace the unit.
Difficulty installing the bottom bracket into the frame
Ensure frame threads are clean and free of debris; use anti-seize or grease on the threads to ensure smooth entry.
Pros and Cons
Pros
- High durability due to heat-treated chromoly construction
- Low maintenance requirements thanks to sealed cartridge bearings
- Reliable and precise spline interface reduces crank movement
- Integrated chainline control feature simplifies installation
Cons
- Compatibility limited strictly to Truvativ 12-spline systems
- Heavier than high-end external bearing bottom brackets
- Requires specialized tools for correct installation
Setup, Compatibility & Care
Installation requires a specific 12-spline bottom bracket tool that matches the Truvativ Powerspline standard. Always ensure the bottom bracket shell on your frame is clean and lightly greased before threading in the unit. It is crucial to respect the recommended torque specifications to prevent damage to the frame threads or the splines themselves. For care, avoid using high-pressure water sprayers directly at the bottom bracket area during cleaning, as this can force contaminants past the rubber seals and into the bearings. If you notice any creaking or play in the cranks after heavy seasonal use, check for loose crank bolts first, as these are frequently the culprit before internal bearing failure.
