• Kit configuration:
• 2 front hub / 2 rear hub / 0 cassette body
• We do not include the cassette body bearing due to Mavic's design. They don't recommend changing this bearing.
• We have a large database of wheel bearing specs, but manufacturers make changes from time to time. Try as we might, we can't always know if your particular wheels use the stock bearings or if a change was made. If you want to make sure we are sending the correct bearing sizes and quantities for your hubs, please email us to find out what sizes this kit uses. Be sure to include the model and year of your wheels.
