Tripeak T47A 77.5mm 24mm/DUB/30mm

TRIPEAK STEEL BEARING 3-IN-1 BOTTOM BRACKET SYSTEM - 24/29/30MM

The Tripeak Steel Bearing 3-in-1 is built for riders who want one bottom bracket that survives crank changes instead of buying a new BB every time the drivetrain changes. With P05 precision steel ball bearings, an interchangeable 3-in-1 core that accepts Shimano HTII 24mm, SRAM DUB 28.99mm and ROTOR 3D+ 30mm spindles, ZeroCreak alignment and Twist-Fit installation on the press-fit shells, this is the workhorse of the Tripeak range.

At Mackay Cycles, we see the Steel Bearing 3-in-1 as the sensible replacement choice for riders wanting a quiet, durable bottom bracket that will carry over to their next crankset, whether that is Shimano, SRAM or ROTOR, around Mackay and beyond.

Key Features

• 3-in-1 Core System — one bottom bracket body accepts Shimano HTII (24mm), SRAM DUB (28.99mm) and ROTOR 3D+ (30mm) crank spindles via interchangeable caps
• TRiPEAK S-Series P05 precision steel ball bearings — 0.005mm inner-race eccentricity (out-of-roundness)
• ZeroCreak construction — dual-sided locking aligns the bottom bracket to the crank spindle to stop creaking under load
• Twist-Fit installation on the press-fit shells (BB30, PF30, BB86/92, BBright, BB386) makes fitting and removal easier than a plain press-fit cup
• Patented Snug Fit plastic-steel bushing on press-fit shells protects the frame shell during installation and corrects shell tolerances
• Bearing core is serviceable and replaceable without replacing the cups
• Available across ten frame standards — BSA, ITA, T47, T47A, BB86/92, BB30, PF30, BBright and BB386
