Frequently Asked Questions
Everything you need to know about high-performance Kogel products and services.
What makes Kogel ceramic bearings different from standard steel bearings?
Kogel ceramic bearings are engineered to reduce friction and increase durability. We use high-grade silicon nitride balls and custom-designed races that resist corrosion and maintain their shape better than steel, resulting in a smoother, faster ride with less watt loss.
How do I choose the correct bottom bracket for my bike frame?
Selecting the right bottom bracket depends on your frame's shell type and your crankset's spindle diameter. We recommend using our 'Bottom Bracket Selector' tool on the website or contacting our technical support team with your bike's make and model for a guaranteed fit.
What is the 'Guaranteed Performance' warranty policy?
We offer a two-year warranty on all our products against manufacturing defects. To keep your warranty valid, we require an annual service of the bearings. We stand behind our quality and want to ensure your gear performs at its peak for years to come.
Do you offer international shipping?
Yes, Kogel Bearings ships globally. Shipping costs and delivery times vary by destination. Please note that international orders may be subject to local import duties and taxes which are the responsibility of the customer.
What is your return policy for unused items?
We accept returns on unused, uninstalled products in their original packaging within 30 days of purchase. Once a bearing has been pressed into a frame or installed on a bike, it is no longer eligible for return due to safety and quality standards.
How often should I service my Kogel ceramic bearings?
For optimal performance, we recommend servicing your bearings once a year or every 3,000 to 5,000 miles. If you frequently ride in wet or muddy conditions, more frequent maintenance may be necessary to ensure maximum longevity.
