Pioneers of chain waxing began decades ago to apply paraffin instead of oil to the chain – in essence, using candle wax. A drivetrain lubricated in this way attracts hardly any dirt, and where dirt doesn’t stick, there’s less wear and tear. Much less wear and tear. On the road, of course, but particularly when cyclo-crossing or gravel biking in damp woodland, for example. However, as waxing requires quite a bit of preparation – the parts must be completely free of grease before application so that the wax can adhere at all – it remained a niche activity for a long time. That has changed. Nowadays, pretty much every well-known lubricant manufacturer has wax in its range, joined by countless companies that have made waxing their speciality. The market has literally exploded. Essentially, there are two product lines: hot waxes and drip waxes. The former must be melted down, and chains must be dismantled before being immersed in the hot wax – which makes the procedure rather laborious. Drip waxes, on the other hand, are applied straight from the bottle – just like oil. According to manufacturers, however, hot waxes are said to be superior. As drip waxes are easier to use, however, the market seems to be moving more in this direction. Both methods can also be combined. For example, you can re-lubricate a chain that has been treated with hot wax using drip waxes before immersing it in the hot wax bath again for a general overhaul after a few cycles.
We can confirm from years of practical experience that waxed chains hardly attract any dirt. Even after a ride through the thickest mud, a waxed chain remains remarkably clean. And that, in turn, is the basis for a significantly longer service life for chains, sprockets and chainrings – with wax, they can last several times longer! As replacing worn chains, sprockets and chainrings on modern bikes can cost hundreds of euros – cassettes cost up to 500 euros – durability is an immensely important factor in running costs. However, cleanliness doesn’t just benefit the mechanics; waxed chains leave little trace; only a little wax trickles out during the running-in period. This makes handling the bike more pleasant. The benefits are literally tangible, particularly when transporting the bike (in a car) and when frequently changing bikes. Practical problems mainly arise during rides in the rain. Putting a wet bike into the garage has never been a good idea – and certainly not with a waxed drivetrain, as this offers less protection against corrosion than oil, which, unlike wax, can seep into the surface. Consequently, the first signs of rust can appear overnight on a waxed chain that has been parked whilst wet. That is why waxed drivetrains should be dried off after every ride in the rain and, ideally, re-lubricated. How long a waxed chain lasts varies. Some manufacturers promise mileage of up to 1,000 kilometres per application. Whilst this may be true under certain road conditions, in our experience 200 kilometres is a more realistic figure for everyday road cycling, and significantly less in winter conditions. Generally speaking, an oiled chain will run for more kilometres between oilings without any problems.
Our test range comprises 16 products from eleven manufacturers. Six hot waxes are compared with ten drip waxes. The price per gramme varies between 9 and 50 cents. Waxes are therefore relatively expensive. This is certainly due less to the price of the base material, paraffin, than to the additives mixed into the waxes. Solid lubricants such as tungsten disulphide or special ceramics, which are designed to adhere to the metal surface, are expensive ingredients. Wax is also economical. For a hot waxing session, only around four grams of wax is actually needed. A 400-gram packet therefore lasts a small eternity. With drip waxes, how long a bottle lasts depends on its viscosity and how it is used. Even a small container can go a long way, as is the case with Dry Fluid, which is very thin in consistency and fitted with a fine dispensing tip. To give an idea: To keep a fleet of eight bikes running, the author required 240 millilitres of liquid wax in one year. Estimated total mileage: just under 20,000 kilometres (wax cost: 0.23 cents per kilometre). Some manufacturers categorise waxes according to their intended use, distinguishing between smooth-running products and endurance waxes, which are designed to deliver higher mileage. Three manufacturers (Dynamic, Motorex and Toniq) also advertise biodegradable waxes. For the test, we applied the waxes to degreased Shimano XT chains and subjected them to an efficiency test on a specialised test rig, under high to very high loads ranging from 370 to 680 watts. We compared the waxes with the original lubrication on the Shimano chains as well as with a very good chain oil.
Our test shows that the manufacturers’ claims are indeed true: waxes lubricate very well, with the best ones being more efficient than a very good high-end chain oil – albeit only just. The gain in efficiency compared with Shimano’s original lubrication – which is really more of a corrosion inhibitor – is, however, significant. A good wax saves 5.5 watts here at a drive power of 370 watts. That’s 1.5 per cent, after all. Is that a lot or a little? That’s in the eye of the beholder. Replacing the original chain lubrication with something faster should be a must, at least for competitive cyclists. When the chain is worn or dirty, the differences between the products are presumably even greater than those determined in our test. At higher power outputs, the efficiency of the chain drive generally increases. The ranking for high power is therefore not entirely identical to that for lower power (see chart on the right). Our measurements show that most waxes perform very well even at very high power. A clear trend is emerging: hot waxes perform reliably well and top the rankings. However, some drip waxes are also right up there with the leaders. A wax-free dry lubricant, Dry Fluid, also performs very well.
Waxing makes a difference. Faster speed, longer life, and clean fingers. The most time-consuming part is degreasing the chains. Pre-waxed chains make getting started particularly easy. Once you’ve got the hang of waxing, it’s only slightly more time-consuming than oiling and saves you money, as the drivetrain lasts longer, which more than makes up for the cost of waxing. - Robert Kühnen, Test Engineer

The wax is melted down and the dismantled chain is placed in the wax bath. Advantage: complete filling of the chain with wax, Disadvantage: greater effort
It is applied just like oil from a bottle.
A practical approach is to combine both methods: preparation with hot wax, followed by re-waxing with drip wax. Pre-waxed replaceable chains are another option.
Wax-free lubricant. Very economical – only a small amount is needed. Also ideal for re-lubricating whilst out and about
All-weather wax without additives. Inexpensive, biodegradable, but not particularly easy to apply
Contains ingredients similar to Hot Wax, but is significantly more expensive and less effective. Comes with application sponges included
Water-based drip wax. Biodegradable. Durable, particularly at high power levels. Good value for money

Wax cannot be tested using conventional methods for isolated lubricants. That is why we tested it in the same way we use it – whilst driving. In doing so, we measured how efficiently the drive system operates. However, we drove on the spot, as such precise measurements are only possible in a laboratory. Test set-up: Our test rig measures the difference between the input and output power in the chain drive. This is technically challenging because the chain’s efficiency is generally very high. The measurement technology must be able to withstand substantial forces whilst still providing high resolution. This is achieved by a setup comprising a 1.5-kW drive and two industrial Burster torque sensors, which can handle up to 200 Newton-metres of torque – more than even the strongest cyclists can muster from their muscles. Unlike humans, the machine keeps going even at intensities where we’d be sick to our hearts with lactic acid.
Test procedure: To compare the lubricants, we prepare 20 Shimano XT chains from a single production batch by degreasing them with our test waxes, allow them to set, and then cycle for an hour at 370 watts – which for most people is the equivalent of a fairly strenuous climb. We record the change in efficiency throughout this process. The average value over the final 20 minutes is our measured value. We cycle at 92 revolutions per minute and a gear ratio of 32/17 – without any chain drift. The chain is guided through a derailleur, and the sprockets are made of steel. In the second part of the test, the run-in chains are subjected to a load of 680 watts for ten minutes. Here, too, we record the efficiency. This test provides insight into the extent to which the lubricants function even under extreme loads. Finally, as an example, we subject a waxed chain to a gruelling endurance test following a mud bath. We also monitor the change in efficiency throughout this test.
