Tripeak T45 82.5mm 3-in-1 G5 Ceramic Bottom Bracket COLNAGO

One Bottom Bracket. Three Crank Standards.

The Tripeak T45 82.5mm 3-in-1 Ceramic Bottom Bracket has been developed for modern Colnago frames using the T45 threaded standard. 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 CNC-machined 6061 aluminium cups, the system delivers exceptional rotational efficiency, long-term durability and the secure, creak-free performance that threaded bottom brackets are known for.

Why the 3-in-1 Core System?

Most bottom brackets are designed around a single crank spindle diameter. Change your crankset and there's a good chance you'll also need to replace the bottom bracket.

Tripeak's 3-in-1 Core System eliminates that problem.

Using interchangeable internal sleeves and adapters, a single bottom bracket can accommodate:

• Shimano Hollowtech II (24mm)

• SRAM DUB (28.99mm)

• Rotor 3D+ (30mm)

That means upgrading your crankset no longer means replacing an otherwise perfectly good bottom bracket. Simply install the correct adapters and you're ready to ride.

It's a smarter system for riders and a simpler 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 incredibly smooth rotation, low friction and consistent performance in all riding conditions.

Whether you're racing, training or simply looking for the most refined drivetrain possible, ceramic bearings help maximise the efficiency of every pedal stroke.

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 T45 threaded interface provides a secure connection between frame and bottom bracket, helping reduce movement, improve stiffness and eliminate the creaks often associated with lower-tolerance systems.

Combined with CNC-machined 6061 aluminium cups and a reinforced PA+GF composite centre sleeve, the result is a bottom bracket engineered for years of reliable performance.

Why We Stock It

The Tripeak T45 3-in-1 Bottom Bracket solves a genuine problem. Instead of locking you into a single crank standard, it gives you the flexibility to move between Shimano, SRAM and Rotor cranksets without replacing the entire bottom bracket. Combine that with premium ceramic bearings, precision manufacturing and the proven reliability of the T45 threaded interface, and you have one of the most versatile bottom brackets available for modern Colnago road bikes.
