What the Garage is
Every calculator on this site needs the same handful of numbers — your weight, your tire width, your gearing. The Garage is where they live. Enter them once and the tire pressure calculator opens already knowing your bike; change your cassette here and the gear chart updates itself. Own more than one bike? Save them all — the active one is what every tool starts from, and the comparison table above puts them side by side.
A 165 lb rider runs about 63 psi in a 28 mm road tire and 28 psi in a 45 mm gravel tire — same physics, same 15% tire drop, twice the casing. That gap is exactly why saved bikes beat re-typing your setup into a generic calculator every time.
Where the numbers come from
Nothing on this page is a guess of its own: every figure is computed by the same engine as the calculator it links to, so the Garage and the tools can never disagree. Pressures come from the 15% tire-drop model with your weight on each wheel; gearing range and speeds come from your actual sprockets, not a "smallest and largest" shortcut; the training card runs the Coggan zone tables, the critical-power model and the heart-rate zones from the anchors those calculators saved. Each card links to its calculator for the full picture — rim widths and hookless limits, gear-by-gear charts, the printable zones sheet, the works.

The Garage lives in your browser's local storage. There's no account, nothing is sent to us, and we couldn't read it if we wanted to. The honest trade-off: it won't follow you between devices or browsers, and clearing your browser data clears it. The button below erases everything this site has stored, immediately and completely.
