The cheapest performance upgrade on any bike is a clean drivetrain. This is the hub where we show the working.
What you’re actually deciding
The cheapest performance upgrade available on any bicycle is a clean drivetrain. It costs about twenty minutes and a bottle of lube, it makes the bike quieter and faster, and it multiplies the life of parts that cost real money. Nothing you can buy comes close on return.
Which makes this the hub where the arithmetic is most worth doing, and where almost nobody does it. The lube category in particular is argued about endlessly on price and brand, and the bottles range from 4 oz to 32 oz — one is even a two-pack — so the shelf price tells you nearly nothing. We divide it out for you, live, in the chain lube roundup.
The number that saves the most money
Chain wear. A chain stretches as it wears, and a stretched chain reshapes the teeth of your cassette to match. Replace the chain at the published threshold and you keep the cassette; run it past and you buy both. The tool that measures it costs less than a takeaway and pays for itself the first time you use it.
This is the whole site’s thesis in one component: it’s a published threshold, a cheap gauge, and a decision anyone can make correctly with no opinion involved. See when to replace a bike chain.
Where our honesty policy actually helps
We don’t test products, and on roundup pages that’s a limitation we’re upfront about. But the how-to guides here are different — they’re not about products at all. They’re about procedures Stephen has genuinely done many times, on his own bikes, and they’re where the lab-backed competitors are thinnest. A dynamometer doesn’t help you explain why the wax won’t stick to a factory-greased chain.
Start with cleaning a chain and fixing a flat. Between them they cover most of what actually goes wrong.
Heads up: we earn a commission if you buy through the links on this page, at no extra cost to you. It never decides what makes the list — here’s how that works.

Why function count is a vanity metric, the four tools that actually get you home, and what each listing refuses to publish.
The number that matters
Cost per millilitre, not cost per bottle.Chain lube bottles here run from 4 oz to 32 oz and one listing is a two-pack, so the headline price is close to meaningless. Divide the live price by the volume printed on the listing and the ranking changes completely — the cheapest bottle on the shelf is rarely the cheapest lube.
We do that division live on the chain lube page, from the current Amazon price and the manufacturer’s published volume. Nobody else in this category publishes it. What we deliberately don’tpublish is cost per application — the number you actually want — because no manufacturer publishes applications per bottle, and we’re not inventing a denominator to fill a column.

How often should I clean and lube my chain?
The honest test is your ears and your fingers, not a schedule: if it’s audible, it’s dry; if a finger comes back with black paste, it needs cleaning before it needs lube. The procedure.
Which chain lube should I buy?
It depends on your weather and whether you’ll degrease properly — wax on a dirty chain is worse than nothing. We rank seven of them on published data and live cost per millilitre in the lube roundup.
Can I use WD-40 on my chain?
Not the original can — it’s a water displacer and will strip your chain. WD-40 also makes an actual bike chain lube, which is a different product entirely. The confusion is why we rank it last: the lube roundup.
When should I replace my bike chain?
At a measured wear threshold, not a mileage. A cheap gauge tells you, and replacing on time saves the cassette — the thresholds and the maths.
Is tubeless worth the hassle?
On gravel, usually yes. For a commuter who wants to never think about it, usually no — sealant dries out and needs topping up, and a tubeless failure at the roadside is worse than a tube. The honest trade-off.
