Review: Peaty’s bicycle assembly grease

A good all-purpose grease is a must in the shop, and Peaty’s Bicycle Assembly Grease is ideal for modern bicycle applications.

‘Peaty’ is, for the uninformed mountain biker, Steve Peat, former downhill world champion and Sheffield legend. Since his retirement he has been involved with the Royal Racing clothing brand and now Peaty’s – its line of cleaning products, tubeless tire accessories and lubricants.

For those who haven’t yet fooled around with loose bottom brackets and ball heads, and with the noble exception of Shimano’s stubborn grip on cup-and-cone wheel bearings, the main uses for The grease in modern bicycle maintenance is to prevent metal parts from getting stuck together. In practice, this mainly means when installing cartridge bearings and cranks, and on bolt threads. You may also wish it for steel or aluminum seatposts. A smear on the cable nipples prevents them from getting stuck inside the shift levers.

Peaty’s says its bicycle assembly grease is ideal for these applications. Scientific data is published on the website as to why it was formulated with “synthetic esters”. The advantage of these esters over regular synthetic oils, Peaty’s explains, is their ability to both adhere to metals and flow easily. These properties are both thanks to their polarized molecules, which both attract them to metals and repel them from each other. To reassure myself, I dived into an article published in ‘Lube: the European magazine for the lubricants industry’ (I never miss an issue); and it says: “The negatively charged oxygen of the ester chemical function will bind to the positively charged sites of the metal surfaces.” So, how are you.

Science out of the way, let’s be fat. I have used it on every bike I have serviced over this busy summer and there is no indication that it is not a great all purpose grease. It is medium in thickness, spreads thin and evenly, and is very smooth. It is easy to wash off any excess with a citrus degreaser.

It is not easy to test longevity and weather resistance over a six week summer test period. So far, however, it has remained in place in the brake and mechanism pivots, even in the exposed and vulnerable lower headset bearings. Peaty’s says the grease has high wash resistance and is certainly thick enough to do a decent job in wheel hub bearings; but if you like the ultimate protection where seals can be bypassed, you might want to study marine grade greases.

Most fats seem to be sold by volume rather than by weight, as Peaty’s has chosen to do, so price comparisons are not easy. However, as a marker, Premium Finish Line bicycle grease has a full retail price of £ 29.99 for 457g, so a quick math shows that’s 6 1/2 p per gram compared to Peaty’s 10 p per gram.

While chain lubricants fall on the road.cc review desk every week, we don’t see a lot of grease products. We have to go back to 2016 for Shaun’s favorable review of Green Oil’s Ecogrease, which currently costs £ 9.99 for 200ml; although I have no idea how much a milliliter of fat actually weighs.

Congratulations points go to the tube made from recycled material, but on the downside, I couldn’t get the thread to work on the neck with one of the grease applicators lying around in my workshop (you apparently need of an M15 thread), which was a bit of a nuisance when trying to squeeze grease into inaccessible pivots or wheel hubs.

A little surprise was the fresh mint aroma. Do not mix it with your toothpaste.

Verdict

Smooth, moderately thick grease that easily spreads over bearings and bushings, but not all grease guns fit the tube

Tell us a little more about the technical aspects of the product?

Peaty’s scientists explain:

“For it to lubricate really well, a good grease needs molecules that flow easily over each other (less drag) and coat the metal surface thoroughly and evenly, to avoid metal-to-metal contact ( which causes parts to wear out).

In intellectual parlance, our base oils have been formulated from synthetic esters with marked polarity.

Ok … Who is the ester and why is it in your oil ?!

Ester is not a woman, she is a variant of synthetic oil! Esters are more expensive than pure synthetic oils because the ingredients must all be collected from natural sources and then synthesized in much smaller amounts than regular synthetic oil.

The main reason for using ester oil is its quality of adhesion to surfaces. Ester oil has an electrochemical bond because the ester molecule is polar, much like a fridge magnet. He’s drawn to metal and sticks like a peat hand to a cool pint of Yorkshire ale.

Also, because of this electrochemical charge, fat naturally distributes itself evenly over a surface as each molecule will repel each other – as if trying to push together the two positive ends of a magnet. “

Peaty’s Bicycle Assembly Grease is compatible with all oils of a mineral or synthetic nature, except PAG (polyalkylene glycol) based products.

Looks like a quality grease, easy to spread thinly and evenly on the bearings. So far it has stayed where I put it.

Rate the product for its durability:

Peaty’s claims it has high resistance to water washout. While I didn’t have any winter conditions to ride during the test period, this is still where I put it in my lower helmet race (a notoriously demanding environment!) And the mechanical pivots.

Evaluate the product for its value:

5/10

Using synthetic esters as opposed to regular synthetic oils means that this product costs more than some all-purpose products, but even so, given the price comparisons outlined below, it’s not overly expensive.

Tell us how the product performed overall when used for its intended purpose

This is a beautiful, medium thickness blue grease that is ideal for coating sealed bearings, threads and axles. It is going well and economically and so far it has remained where it is.

Tell us what you particularly liked about the product

Mmm, fresh mint!

Tell us what you didn’t particularly like about the product

You need an M15 threaded grease gun to fit this tube. I tried it with all three (!) Guns in my workshop and it didn’t fit any of them.

How does the price compare to similar products on the market, including those recently tested on road.cc?

Price comparisons are not easy as a lot of fats are sold by volume rather than by weight. However, Park Tool High Performance Grease is priced at £ 13.99 for 113g, and Finish Line’s Premium Bicycle Grease has a full retail price of £ 29.99 for 457g. Respectively, these work at 12p and 6 1 / 2p per gram of fat, compared to Peaty’s 10p.

Unless you extend the test to winter conditions, it is difficult to criticize the performance of this grease. This gives the impression of a quality product with excellent thickness and consistency for smoothness on sealed bearings and in the headset, and weather resistant enough for wheel bearings without being stiff or claggy.
