Tripeak BB86/BB92 3-in-1 G5 Ceramic Press Fit Bottom Bracket

One Bottom Bracket. Three Crank Standards.

The Tripeak BB86/BB92 3-in-1 Ceramic Bottom Bracket has been developed for bikes using the popular BB86 and BB92 press-fit bottom bracket standards. Built around Tripeak's innovative 3-in-1 Core System, it allows a single bottom bracket to support Shimano Hollowtech II, SRAM DUB and Rotor 3D+ cranksets, making future drivetrain upgrades simpler than ever.

Featuring precision G5 Ceramic Bearings housed in lightweight PA+GF composite cups and sleeve, the system delivers exceptionally smooth rotation, low weight and long-term durability. Whether you're building a lightweight road bike or a high-performance mountain bike, the 3-in-1 Core System gives you the flexibility to change crank standards without replacing the entire bottom bracket.

Key Features

• Designed for BB86 Road and BB92 MTB press-fit frames

• Innovative 3-in-1 Core System

• Compatible with Shimano HTII (24mm), SRAM DUB (28.99mm) and Rotor 3D+ (30mm)

• Premium G5 Ceramic Bearings

• Also available with P05 Precision Steel Bearings

• Lightweight PA+GF composite cups and centre sleeve

• Includes all required adapters and spacers

• Lightweight 47g (G5 Ceramic) or 50g (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, training or tackling demanding off-road trails, both options are engineered to deliver long-lasting performance.

Lightweight Composite Construction

The cups and centre sleeve are manufactured from reinforced PA+GF composite material, providing excellent strength while keeping overall weight exceptionally low.

The composite construction also helps isolate the bearings from contamination while providing a durable interface with the frame.

Why Choose BB86 / BB92?

BB86 and BB92 remain two of the most widely used press-fit standards in modern cycling. Their large shell diameter allows frame manufacturers greater freedom when designing stiff, lightweight carbon frames while maintaining excellent bearing support.

When manufactured to tight tolerances and paired with quality components, a precision press-fit bottom bracket delivers excellent performance, low weight and reliable durability.
