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

Full Shipping Policy

1. General Shipping Information

All online orders are processed and shipped from our Mackay store during normal operating hours (8:30am–5:30pm, Tuesday to Friday). Our goal is to dispatch your order within 24 hours of placement, excluding weekends and public holidays.

Parts, Clothing and Accessories are shipped via Australia Post or other parcel courier. Bicycles, Frame-sets and indoor smart-bike trainers are shipped via specialist bike courier services to ensure they arrive in suitable condition.

2. Warehouse-Supplied Items

Some items on our website are supplied directly from brand warehouses interstate. Where this applies, the product page shows a note such as "Available to Order from [Brand] Warehouse — ships to Mackay Cycles, then ready for Click & Collect or local delivery in approx. 5–10 working days depending on brand."

These items route through our Mackay store before dispatch, so we can check, pack and freight them properly. Please allow the stated working days for the item to arrive with us before it's dispatched to you.

A small number of items ship direct from the supplier to your address — where that applies, the product page will say so.

3. East Coast Australia Bike Freight

Our $200 flat-rate Bicycle freight, $150 Frame-set freight, and indoor smart-bike freight ($200 Zwift Ride / $400 Wahoo KICKR BIKE), are available to addresses in Queensland, New South Wales, Victoria, the Australian Capital Territory, Tasmania and South Australia. Freight to Western Australia and the Northern Territory is available by quote — please contact us with the item and your address and we will provide a custom quote.

Moranbah local delivery: We deliver to Moranbah (postcode 4744) for a flat $80 via local courier Movin' On With Muttley — just select Local delivery at checkout. Ordering more than one bike? Contact us and we'll sort the delivery.

4. Click & Collect at Mackay Cycles

Free in-store pickup is available from 7/8–14 Centurion Drive, Paget QLD 4740. Most online orders are ready within 4 business hours; we'll send a notification when your order is ready to collect. Items not on-floor (typically supplied from interstate warehouses) are not currently available for immediate Click & Collect — they'll be ready for collection once they arrive with us (see Section 2). Click & Collect is available as a separate option at checkout.
