Kit

Why it won →Kit

Prices live from Amazon as of Aug 31, 2026. We earn a commission if you buy — here’s how that works. #ad
We have no lab, no test fleet and no testers. Not one product on this site has been in our hands. We could hide that behind the usual phrasing — “in our testing”, “our experts” — and you’d have no way of catching us. That’s exactly why we don’t.
So here’s what we do instead.
We read the manufacturer’s published specs and tell you they’re the seller’s claims, not facts. We compute running costs and show every input, rate and date so you can re-run the arithmetic. We cite third-party test data with its conflicts disclosed— the big chain-wear dataset everyone quotes as “independent” comes from an outfit that sells the lubricants it tests, and we say so every single time. And when nobody has published a number, we print that instead of inventing one.
Read how we research — it’s the most important page here.

ElectricThe motor is the easy part. What decides your purchase is the battery, the class, and what the thing actually costs to run — so that's what we compute.
Loose surfacesGravel is a tire-clearance number and a gearing decision wearing a marketing category's clothes. Get those two right and the rest follows.
TarmacBeing seen, knowing your numbers, and sitting comfortably for four hours. Everything else on a road bike is negotiable.
DrivetrainGroupset tiers are a pricing ladder with engineering attached. Here's what each rung actually buys you, and where the ladder stops being worth climbing.
What you wearA helmet is a certified safety device and a bib short is a chamois with straps. Both are bought badly, for the same reason: nobody explains what's inside them.
MaintenanceThe cheapest performance upgrade on any bike is a clean drivetrain. This is the hub where we show the working.
Four pages that show what this site is for: the arithmetic nobody else publishes, the conflict nobody else discloses, and the two facts the industry would rather you didn’t know.

Cost per charge, cost per mile, and 1,000 miles against a car — every input sourced, every step of the working shown.

Best chain lubeWax vs dry vs wet, the published wear data behind the claims, and live cost per milliliter across seven bottles.

The Shimano and SRAM tier ladders, priced in published grams. What you get climbing from 105 to Ultegra, and why Shimano prints no weight at all below 105.

Every range claim on Amazon, reverse-engineered into the watt-hours-per-mile it assumes — and what the suspicious uniformity tells you.

Chainring Clubis funded entirely by Amazon Associates commission. If you buy through a link here we earn a percentage, at no extra cost to you. Commission never decides a pick — every roundup on this site names at least one product to skip, and our rankings routinely put cheap things above expensive ones, which is the opposite of what a commission-maximizing site does. We accept no sponsored placements and no free products.
