Tripeak T47 68/73mm 3-in-1 G5 Ceramic Bottom Bracket

One Bottom Bracket. Three Crank Standards.

The Tripeak T47 68/73mm 3-in-1 Ceramic Bottom Bracket has been developed for bikes using the versatile T47 threaded bottom bracket standard. Designed to fit both 68mm road and 73mm MTB/gravel T47 frames, it's built around Tripeak's innovative 3-in-1 Core System, allowing a single bottom bracket to support Shimano Hollowtech II, SRAM DUB and Rotor 3D+ cranksets.

Featuring precision G5 Ceramic Bearings housed in CNC-machined 6061 aluminium cups and a reinforced PA+GF composite centre sleeve, the system delivers exceptional rotational efficiency, long-term durability and the secure, creak-free performance that has made T47 one of the most trusted threaded standards in modern cycling.

• Compatible with Shimano HTII (24mm), SRAM DUB (28.99mm) and Rotor 3D+ (30mm)
• Premium G5 Ceramic Bearings
• Also available with P05 Precision Steel Bearings
• CNC-machined 6061 aluminium cups
• Reinforced PA+GF composite centre sleeve
• Includes all required adapters and spacers
• Standard 16-notch bottom bracket tool interface (44mm OD)
• Lightweight 84g (G5 Ceramic) or 91g (P05 Steel), excluding adapters

Why the 3-in-1 Core System?

Most bottom brackets are designed around a single crank spindle diameter. Change your crankset and you'll often need to replace the bottom bracket as well.

Tripeak's 3-in-1 Core System removes that limitation.

Using interchangeable internal sleeves and adapters, one bottom bracket accommodates:

• Shimano Hollowtech II (24mm)
• SRAM DUB (28.99mm)
• Rotor 3D+ (30mm)

That means you can upgrade or change cranksets without replacing the entire bottom bracket. Simply install the appropriate adapters and you're ready to ride.

It's a smarter system for riders and a more practical solution for workshops.

Why Choose Ceramic Bearings?

Ceramic bearings are designed to reduce rotational resistance while maintaining exceptional durability.

Tripeak's ceramic bottom brackets use G5-grade ceramic balls running on precision-machined hardened steel races. The result is exceptionally smooth rotation, low friction and consistent performance in all riding conditions.

For riders who prefer a steel bearing option, the same bottom bracket is also available with Tripeak's precision P05 Steel Bearings, manufactured to extremely tight tolerances for excellent durability and smooth running.

Whether you're racing, riding gravel or simply looking for the most refined drivetrain possible, both options are engineered to deliver long-lasting performance.

Precision Engineering

Performance isn't achieved through ceramic balls alone.

Every Tripeak bottom bracket is manufactured to exceptionally tight tolerances, ensuring accurate bearing alignment and smooth operation from the moment it's installed.

The CNC-machined 6061 aluminium cups provide outstanding strength and durability, while the reinforced PA+GF composite centre sleeve keeps weight low and helps protect the bearings from contamination. Together they create a rigid, reliable interface between the frame and crankset.

Why Choose T47?

T47 has become one of the most popular threaded bottom bracket standards for premium road, gravel and mountain bikes. Combining the stiffness benefits of a large-diameter shell with the reliability of a threaded interface, it helps eliminate movement and the creaking commonly associated with press-fit systems.

Easy to install, simple to service and built for long-term reliability, T47 has become the preferred choice for many modern performance frames.
