No, it is specifically engineered for Cannondale-AI configurations with an 83mm shell.
Yes, a standard press-fit bottom bracket installation tool is required.
No, this is designed exclusively for SRAM DUB cranksets.
The spacer is included to ensure correct lateral spacing and chainline for the Cannondale-AI configuration.
The cartridge bearings are sealed units and generally replaced as a whole rather than serviced individually.
Ensure the bottom bracket is correctly seated and re-torque the crankset to manufacturer specifications.
Verify that no extra spacers are causing excessive preload on the bearings; adjust based on the DUB manual.
Confirm the frame shell size is exactly 83mm and that the shell is perfectly round and clean of paint overspray or metal burs.
Installation of this bottom bracket requires a professional-grade press-fit tool to ensure the cups are seated squarely into the frame shell. Do not attempt to hammer or force the cups into place, as this can damage the frame or the bearing seals.
Regular maintenance involves wiping down the crankset area after washes and avoiding high-pressure water sprays directed at the seal junctions to prevent forcing contaminants inside.
