Ceramicspeed T47a Botton Bracket Shimano Coated Black 47×77

Handmade ceramic bearings in aluminium bearing shells
For cranks with 24mm Shimano Standard

The CeramicSpeed T47a Shimano is an asymmetrical bottom bracket and designed for bike frames with a 77mm shell width. CeramicSpeed bottom brackets offer extreme stiffness, low friction, high reliability and unmatched durability. All bearings from CeramicSpeed are equipped with high-quality CeramicSpeed balls and have been pressed into shells made of aluminum. The ceramic balls are rounder, smoother, harder, lighter and more durable than steel balls.

The CeramicSpeed T47a reduces drag by 75% compared to conventional bottom brackets. The precision dust caps have a snug and secure fit. These fully protect the face of the bearing while providing exceptional performance without compromising.
