Grease

Browse bike grease for sale from riders across the UK. Grease is oil held in a thickener so it stays where it is packed — hub and headset bearings, bottom bracket shells, seatpost, pedal and thru-axle threads — and it is bought in everything from small syringes for a single job to 450g workshop tubs that last several seasons. It suits anyone doing their own bearing work rather than dropping the bike off.

Buying Guide

What sort of grease does a bike need?

A general lithium-complex bearing grease handles most of it, and something marine-grade or explicitly waterproof is better in the places that see standing water — bottom bracket shells, rear hubs and headsets on winter bikes. PTFE-loaded greases such as Park Tool Polylube 1000 and Finish Line's are common on threads and cable ferrules. Anti-seize is a separate compound for titanium bolts and steel-into-alloy fasteners, and carbon assembly paste is separate again: gritty, deliberately high-friction, and used so a carbon post or bar grips at its rated torque.

Grease or chain lube — which goes where?

Grease never goes on a chain. It is too thick to reach the inside of a roller, so it sits on the plates gathering grit and does nothing useful — that job belongs to chain lube. Grease belongs anywhere two surfaces are clamped or rotating in a sealed space, and anywhere a thread needs to come apart again in two years' time.

Can I use car or general-purpose grease on a bike?

For a plain bearing or a thread it usually works, but there are places where it does not. Hydraulic brake and suspension seals are chemically specific — a mineral-oil brake wants a compatible grease at the lever piston, and fork wiper seals want a slick, low-drag product such as SRAM Butter or Slickoleum rather than a heavy bearing grease that adds stiction. Anything that finds its way onto a rotor or pad means new pads, so wipe threads clean after packing.

How do I tell if grease has gone off?

Look for a layer of clear oil sitting on top and a stiff, dry crust below — that is the oil bleeding out of the thickener, and the grease under the crust is generally still usable. What ruins a tub is contamination: grit or brake fluid introduced on a finger or a dirty tool cannot be got back out. Use a spatula or a syringe, keep the lid on, and store it away from a heater.

Is a big tub better value?

Usually, because a single service uses very little and a 450g tub outlasts several overhauls, but only if it stays clean and sealed for that long. Small syringes make sense for a specific job — packing one hub, or greasing a set of pedal threads — and for suspension-specific products you will not use often. Sealed tubs and unopened syringes are the ones worth buying from other riders; see the rest of the range under lubricants and the damper fluids under suspension oil.
