PF30 Bottom Bracket

This e*thirteen bottom bracket is compatible with Pressfit 30 bottom bracket shells, and cranksets with 30mm diameter spindles. It offers an advantage over standard Pressfit BB's because the cups thread together in the center, eliminating the unwanted movement that causes creaking sounds and reduced bearing life. The cups are made of durable yet lightweight aluminum and house angular contact bearings with custom low-friction seals. It works with e*thirteen 30mm spindle cranksets, as well as other 30mm spindle cranksets from other brands (see tech specs for compatibility).
