Guides

The pages that aren’t a calculator.

Most questions on this site end in a number, and the calculator that computes it already carries the full article. These are the rest: reference charts you’ll want beside the bike, and the handful of topics where the answer is a method or a decision rather than a result.

Reference charts

Sourced numbers in one place, printable.

Fit

Measuring, and what hurts when it’s wrong.

How to measure your inseam In the works The book method, done properly — the one number every fit calculator on this site starts from.
Hands, knees or backside hurting? In the works Symptom → the fit parameter usually behind it → the calculator that moves it.

Workshop

Setup decisions a calculator can’t make for you.

Tubeless vs tubes In the works What tubeless actually buys you at your pressures, and when a tube is still the right answer.
Bike maintenance schedule What to check before every ride, and what to service by miles and hours — a printable checklist, no email. Open →

Training

Getting the most from the trainer months.

Indoor trainer setup In the works Fan, tire, tension, calibration — and why the trainer reads differently from the road.
Century training plan In the works Twelve weeks to 100 miles, printed in your own watts from your FTP.

Why so few guides?

Because the calculators already are the guides. "How do I find my saddle height", "what pressure should I run", "how do I calculate TSS" — each of those is a full article on the page that does the arithmetic, with tables computed from the same engine as the tool, so the explanation and the number can never disagree. Writing a second page on the same question would split the answer in two. A guide earns its place here only when there's no single number to compute: a reference chart of published values, a measuring method, a symptom that could be several things, or a setup decision.

What every guide promises

The same things every calculator does. Every figure names its source — a manufacturer's manual, a published study, a standards body — and the honest note stays in when it's inconvenient. Where a chart is worth having beside the bike, it prints on one page with no email and no signup. And each guide hands you to the tool that runs your numbers, because the chart tells you the rule and the calculator tells you your answer.
