CeramicSpeed T47/68 Outboard Shimano Bottom Bracket (Black)
107832
A threaded T47 bottom bracket that pairs oversized-interface stiffness with genuine ceramic bearings — built for Shimano 24mm spindle cranks on road and tri builds.
Overview
T47 was originally developed by custom frame builders looking for a way to combine the stiffness of oversized bottom bracket interfaces like PF30 and EVO386 with the long-term reliability of a threaded design. This CeramicSpeed version takes that T47/68 standard — a 47mm threaded inner diameter across a 68mm-wide shell — and fits it with genuine CeramicSpeed ball bearings for exceptionally low friction.
Because the cups thread directly into the frame rather than pressing into the shell, installation and future removal follow a conventional, creak-resistant threaded approach rather than the press-fit method that's given some oversized standards a reputation for creaking over time. It's built specifically for Shimano's 24mm spindle road cranks and 68mm-wide T47 outboard frames.
Why You'll Like It
Genuine CeramicSpeed bearings
Precision ball bearings and hardened-steel races deliver meaningfully lower friction than a stock bottom bracket.
Threaded, creak-free reliability
A threaded T47 interface avoids the creaking issues some press-fit oversized standards develop over time.
Oversized stiffness, threaded convenience
Combines the structural benefits of PF30/EVO386-style oversized interfaces with a genuinely serviceable threaded design.
Complete installation kit
Comes with everything needed to fit: both threaded cups, dust covers, spacer tube, grease, and decal.
Who Is It For?
This suits road and triathlon riders with a 68mm-wide T47 outboard frame and a Shimano 24mm spindle crank who want a genuine efficiency upgrade over a stock bottom bracket, or who are rebuilding a frame around this specific standard.
It's intended specifically for frames built to the matching T47 outboard standard — have your BOTS mechanic confirm your frame's bottom bracket shell before ordering, since this isn't a universal conversion solution.
Good to Know
Installation requires a BBT-69 bottom bracket tool. Have your BOTS mechanic confirm your frame's exact shell width and your crank's spindle diameter (24mm) before fitting.
