Product Details

Overview & Technology

Wheels Manufacturing Pressfit 30 (PF30-BB) is a robust, no-nonsense press-fit bottom bracket engineered to drop into PF30 frames with 68/73mm shell widths. The assembly uses 46mm outer cups and high-quality sealed steel bearings sized for 30mm crank spindles, providing a reliable interface for modern road and performance cranksets. The cups are CNC-formed to precise tolerances to ensure even press-fit seating and long bearing life. Sealed steel bearings offer dependable durability and predictable friction characteristics—ideal for riders who want low-maintenance performance without the premium expense of ceramic bearings.

Key Features

Designed for durability: The PF30-BB uses sealed steel bearings that resist contamination and hold up under heavy training and daily riding. Expect consistent roll and long service intervals when installed correctly and maintained periodically. • PF30 shell compatibility: 46mm cup diameter for PF30 shells. • Shell widths: fits both 68mm and 73mm frames. • Crank spindle: optimized for 30mm diameter spindles. • Finish: black cups for a discreet factory look.

Fit & Compatibility

This bottom bracket is made specifically for PF30 (press-fit 30) frames with 68mm or 73mm shell widths. The 46mm cup diameter is the common press-fit size for PF30 shells; verify your frame's specification before purchase. The unit is intended for cranks with a 30mm spindle diameter—measure your crank spindle or check manufacturer specs to confirm fit. Note: Press-fit installations rely on proper frame tolerances. If your frame shows play or creaking after installation, have the shell faced and rechecked by a bike shop. Use the appropriate press-fit tool and a light application of threadlocker/retention compound on aluminium shells to reduce creak risk.

Who It's For

This Pressfit 30 bottom bracket is aimed at road and performance cyclists who ride PF30 frames and run 30mm spindle cranksets. It's an excellent choice for riders seeking a durable, low-maintenance replacement or upgrade without the added cost of ceramic bearings. It's also suited to mechanics and home mechanics who prefer a proven steel-bearing solution for training bikes, daily commuters, or mixed-weather riding where long-term durability matters more than shaving grams.

Frequently Asked Questions

Will this bottom bracket fit my frame?

This unit fits PF30 (PressFit 30) frames with a 46mm cup diameter and 68mm or 73mm shell width. Verify your frame specifies PF30—measure the shell or consult the manufacturer before buying.

Which crank spindles are compatible?

The Pressfit 30 is designed for cranks with a 30mm spindle diameter. It will work with most modern 30mm crank systems from major manufacturers; confirm your crank spindle spec to ensure compatibility.

How long will the bearings last and how do I maintain them?

Sealed steel bearings are durable and low-maintenance; lifespan depends on riding conditions. Routinely rinse after wet rides, inspect for play or roughness, and replace bearings if you detect grit or noise. Typical service intervals for road use are 1–3 years depending on mileage and exposure.

Do I need special tools for installation?

Yes—press-fit installation requires a BB press tool sized for 46mm cups and bearing drivers. For best results and to avoid creaks, have the shell faced if tolerances are suspect and use a light retention compound if your frame is aluminium.

Can I replace the steel bearings with ceramic bearings?

In most cases you can swap bearings for compatible ceramic or hybrid bearings of the same ID/OD dimensions. Ensure the replacement bearings match the PF30-BB dimensions and are intended for press-fit use to preserve proper preload and spacing.

What causes creaking in press-fit bottom brackets and how to prevent it?

Creaks often come from poor shell tolerances, contamination at the interface, or insufficient install technique. Prevent issues by facing the shell, using the correct press tool, applying light retention compound on aluminium shells, and ensuring cups are fully seated.

Buying Guide

When choosing a bottom bracket for a PF30 frame, prioritize shell compatibility (PF30), shell width (68/73mm), and crank spindle diameter (30mm). Decide between steel and ceramic bearings based on budget and performance priorities—steel bearings deliver excellent durability and value, while ceramics offer lower friction and weight at a premium. Also consider serviceability and installation: press-fit systems demand careful pressing and often shell facing to eliminate creaks. If you’re unsure about tolerances or lack the required tools, have a trusted shop perform the install to protect your frame and bearings.
