Experience unmatched performance with the CeramicSpeed T47a Shimano 24mm Gravel CX Coated Bottom Bracket, engineered specifically for gravel enthusiasts seeking durability and efficiency. Designed for frames with an asymmetrical 77mm shell, this bottom bracket combines the oversized interface on the drive side with the reliability of a threaded design, ensuring a secure and precise fit that enhances your bike’s transmission system. Its innovative layout places the non-drive side bearing inside the frame while the drive side bearing sits externally, optimizing power transfer and longevity.
Crafted with CeramicSpeed’s signature coated bearings and UFO Long Life Grease, this bottom bracket excels in all environmental conditions, providing exceptional protection against wear and corrosion. Precision dust covers snugly fit to shield the bearing faces, maintaining smooth operation and preventing contamination. The hand-built bearings guarantee an efficient load transfer from crank to frame, reducing friction to a remarkable 0.3-0.4 watts per set — a significant improvement over standard components.
Installation is straightforward with the CeramicSpeed Dual Socket Tool T45/T47, designed for the 16-notch 52.2mm cup diameter. Each package includes two cups with coated bearings and dust covers, a two-part spacer tube, long life grease, and a sticker sheet, giving you everything needed for a seamless upgrade. The T47a standard merges the benefits of oversized shell compatibility with the security of threading, perfectly accommodating 24mm spindle cranks for a versatile and high-performance setup.
Is the CeramicSpeed T47a compatible with all Shimano gravel cranksets?
It is compatible with Shimano cranksets featuring a 24mm spindle designed for T47a asymmetrical 77mm shell frames.
What maintenance is required for this bottom bracket?
