Product description
The T47 threaded bottom bracket shell utilizes an oversized interface of PF30 and EVO386, but with the benefit and peace of mind of a threaded interface. T47/68 places the bearings outside the width of the frame and is compatible with 68mm wide T47 Outboard frame designs. T47 is a standard created by custom frame builders. It’s threaded, has an inner diameter of 47mm, and is 68mm wide. It has the design benefits of being oversized and wide, but also the practical benefits of threads.
The cups have CeramicSpeed bearings pressed in. There are two bearing options. The Standard Bearing has CeramicSpeed Balls and hardened-steel races. The Coated Bearing has the same balls running on a 3-micron thick coating placed on top of those hardened-steel races for greater durability and less friction still.
This BB is compatible with 68mm frames.
Bottom Bracket tool for installation: BBT-69.
