The Race Face Cinch BB104/107 Bottom Bracket is an essential upgrade for mountain and road cyclists looking to install 24mm spindle cranksets into 41mm press-fit frames. It is ideal for riders seeking a more durable, stable alternative to standard molded plastic press-fit systems, though it does require professional-grade press-fit installation tools to ensure proper alignment and longevity.

No, this specific model is designed exclusively for 24mm diameter spindles.
It is highly recommended to use a proper press-fit installation tool to prevent frame damage and ensure perfect alignment.
Yes, it is designed to be compatible with Race Face, Shimano, and select FSA 24mm spindle cranksets.
The total weight is 95g.
Yes, the unit features a serviceable design, allowing for bearing maintenance or replacement.
Remove the bottom bracket, clean the frame shell thoroughly, and reinstall using a high-quality anti-seize or press-fit specific retaining compound.
Ensure that the correct spacers are used according to your frame's shell width and that the crank bolt is tightened to the manufacturer's recommended torque specification.
This bottom bracket is compatible with 41mm press-fit frames, including BB86.5, BB89.5, and BB92 standards. Installation should always be performed using a dedicated press-fit tool to ensure the cups are seated perfectly square within the shell; hammering the cups into place can damage the bearing alignment or the frame itself. When cleaning your bike, avoid using high-pressure water near the bottom bracket seals to prevent contaminants from entering the bearings. Periodic checks for lateral play in the crankset are recommended to determine if bearing service or replacement is needed.
