The result is a hybrid-ceramic bearing that lasts longer than any steel bearing with spin performance no steel bearing can rival. We’re so confident in the durability of our Ceramitech bearings that we back them with a Lifetime Bearing Exchange warranty. These bearings feature mid-contact seals for extreme performance and durability.

Our Ceramitech bearings feature Si3n4 (Silicon Nitride) balls running in heat treated chrome-steel races that go through a 3-step polishing process to ensure smooth running, durability, and mind-boggling spin performance. Our ABEC-7 all steel bearings feature hardened chrome-steel balls and races for high performance on a budget.\u003c\/p\u003e\n\u003cp\u003eOver-compression of the outer bearing race post-installation is the leading cause of diminished spin performance of pressfit BB’s.To prevent this, all BBInfinite 2-Piece bottom brackets feature our patented Reverse Half Grip bearing retention system, which channels external compression forces away from the center-line of the bearing, thereby letting the balls rotate freely. In fact, a mild over-compression condition will boost performance of our Reverse Half Grip design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWHAT KEEPS BBINFINITE BOTTOM BRACKETS FROM CREAKING?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePrecise machining and modern chemistry combine to ensure every ride will remain creak-free mile after mile, year after year. Our precision allows us to create a cup-set that will match your frame while compensating for frame irregularities while VibraTite530 locks the cups in securely, yet allowing for easy removal when that day comes.\u003c\/p\u003e\n\u003cimg style=\"width: auto; height: auto;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1040\/6576\/files\/New-tool-set.jpg?15860248506358411410\"
