Peaty's SPEED Grease runs 2.5 times faster than our assembly grease, whilst still providing long-lasting performance under extreme Loads. Perfect for use in race hubs, bottom brackets and other fast moving parts. Meeting the ultimate biodegradability OECD test 301B, our SPEED Grease has a high resistance to water wash out, excellent anti-corrosion properties and adhesion to metallic parts while remaining compatible with most other conventional greases. APPLICATION INSTRUCTIONS 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. 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. 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 which 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). 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 synthesized 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. COMPATIBILITY Peaty's Bicycle Assembly Grease is compatible with all oils of a mineral or synthetic nature except for PAG (Polyalkylene Glycol) based products. WHAT IS 'ULTIMATE BIODEGRADABILITY - OECD 301 B'? This is the ability of a product to be transformed into a simple element by living organisms. The OECD 301B standard replaces the obsolete CEC standard (primary biodegradability) 100% POST CONSUMER RECYCLED TUBES Our tubes are made from 100% post consumer recycled plastic. The recycling process is performed according to EU REACH standards using waste LDPE plastic from used plastic shopping bags and food films.
