Peaty’s Speed Grease runs 2.5 times longer than our assembly grease, whilst still providing long-lasting performance under extreme pressures. Perfect for use in race hubs, bottom brackets and other fast-moving parts.
This product is designed for professional use only. If you’re unsure what you’re doing then please consult your local bike shop, workshop or mobile mechanic.
For use in fully sealed parts only.
If using to replace grease in bearings then use only with brand new bearings and seals. Attempting to strip, re-grease and re-build old bearings will result in damaged bearing seals.
Do not allow grease to contact brake disks or pads.
Peaty’s Speed Grease is compatible with all oils of a mineral or synthetic nature except for pag (polyalkylene glycol) based products.
🛠️ ADHESION TO METALLIC PARTS?
The number one requirement for a grease is that it lubricates really well.
In order for it to lubricate really well, a good grease needs molecules that flow over each other easily (less drag) and coat the metal surface thoroughly and evenly, to prevent metal on metal contact (which results in parts wearing out).
In nerd talk, our base oils have been formulated using synthetic esters with a marked polarity.
Ok... Who’s ester and why is she in your oil?!
Ester isn’t a woman, it’s a variant of synthetic oil! Esters are more expensive than straight synthetic oils because the ingredients all have to be collected from natural sources and then synthesised in much smaller quantities than regular synthetic oil.
The number one reason to use ester oil is how well it bonds to surfaces. Ester oil has an electrochemical bond because the ester molecule is polar, sort of like a fridge magnet. It is attracted to metal and sticks like peaty’s hand to a fresh cool pint of Yorkshire ale.
Also, because of this electrochemical charge, the grease naturally distributes itself evenly over a surface since each molecule will repel away from each other - like trying to push two positive ends of a magnet together.

- ALSO, BECAUSE OF THIS ELECTROCHEMICAL CHARGE, THE GREASE NATURALLY DISTRIBUTES ITSELF EVENLY OVER A SURFACE SINCE EACH MOLECULE WILL REPEL AWAY FROM EACH OTHER - LIKE TRYING TO PUSH TWO POSITIVE ENDS OF A MAGNET TOGETHER.
🛠️ Workshop Spin Test
For all you doubters out there... Here's the spin test un-edited and in full so you can see there's been no camera or editing trickery!
For this test we took two identical DT Swiss '350' front hubs and removed all bearings. We then took four identical replacement 6903 bearings and replaced the grease in one pair of bearings with Speed Grease.
One equal spin of both wheels reveals the hub packed with Speed Grease span for over 2.5x longer!
