Ready to upgrade your bottom bracket? Kogel T47 External Ceramic Bottom Brackets have you covered. These Ceramic BBs will fit any specified crankset on a T47 frame with 68mm wide shell with options for on or off-road bikes.
Even new bikes with new high-end drivetrains can, and usually do, ship with bottom brackets using steel bearings. Even if perfectly maintained, those steel bearings just won't roll as smoothly or efficiently as ceramic bearings.
Kogel Ceramic Bearings are:
Choose road bearings for road bikes, cross bearings for mountain bike, gravel and cyclocross or if you frequently ride your road bike on wet roads.
24mm external BBs can be installed with Park Tool BBT-9 or any 16 notch, 44mm diameter tool. SRAM DUB and 30mm external BBs can be installed with Park Tool BBT-79 or any 12-notch 44mm diameter bottom bracket tool.

If you are building up a road or gravel bike with a T47 BB you will be happy you chose a Kogel BB.
The quality is as high as a Chris king or Hambini, about equal cost also. This sure is better than the stock Sram Red DUB BB. What more can be said ?
The fit was perfect, But in order for that you have to have a quality frame also.
