Guides
Bike maintenance, with sources instead of guesswork.
What Shimano, SRAM, KMC and Park Tool actually publish — and where they deliberately give no number.
Bicycle chain lube: which one, how to apply it — and how often
Wet or dry, why WD-40 is not a chain lube, what destroys a chain — and the only interval figures manufacturers actually publish.
Bike tyre pressure: the figures that are actually sourced
Guide figures by width and weight in bar and psi, the front/rear rule, what tubeless really changes — and the hard limit on hookless rims.
How to change a bike tyre — and how to tell when it is due
Getting the bead off without wrecking the rim, finding what caused the puncture, refitting without pinching the tube — plus the sourced wear limits.
Bike chain wax: how it works, and what the lab data actually shows
15,000–20,000 km of chain life against 3,500–6,000 km with oil — the laboratory numbers, the honest truth about watts, and how to switch.
How to change bike brake pads — and how to tell when they are due
The steps, and why Shimano, Magura and SRAM name different limits — plus the one thing a disc brake will never tell you.
