Only Quality Will Do
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:
- More symmetrical (i.e. round) and built to stricter tolerances than steel bearings
- More efficient for power transfer than standard bearings
- And, won't deform, flat-spot, crack or get pitted
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.
Features:
- Guaranteed Performance Warranty, so you can feel confident and secure about your next two seasons of riding.
- Choose "cross" seals for optimal balance of durability and ceramic efficiency
- Choose "road" seals for even better efficiency
- Options for Shimano, SRAM DUB, GXP, or 30mm cranks.
- Pain-free installation for any crank, any frame, with no adapters required
- BB Boost® technology. Placing the bearings as close to the crank arms as possible for increased stiffness and durability
- Serviceable bearings and seal kits so you can easily access and service your bottom bracket
- Bottom bracket cups that cover the internal side of the bearings to protect them from damage during removal
- Top-tier grade 3 ceramic balls for the best ball quality you can get (Ball grade rates the roundness of the ball)
- ABEC 5 bearing tolerance for the best support in a cycling application
- Hardened steel races that won't deform over time
- Races polished to a mirror finish to guarantee the balls run on a smooth surface

Reviews
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.
