the garage
Where your bikes live between rides. Work out what pressure to start at, measure your sag against a real target band, then log it so the next change is a decision instead of a guess. It's free, and the calculator doesn't care what you paid for the bike.
Sag & Pressure Calculator
Your weight, your fork, your travel, your discipline. Not a weight-only formula: a 140mm Pike and a 180mm ZEB want very different air for the same rider, so the numbers are fit to the manufacturer charts per model and travel. You get a starting psi front and rear, the clicks to run, and the exact mm of sag to measure for.
Suspension Log
Log a setup and it stays logged. Pressures, clicks, sag, tokens, and what the bike actually felt like on the trail. Next time you change something you can diff it against the last run instead of trying to remember what you were on in April.
Your Bike, On Paper
Frame, fork, shock, travel, wheel size, geometry. Fill it in once and the calculator stops asking. It doubles as the spec sheet you send a shop when something needs warranty or a service.
Saved Builds
Builds you spec in the Builder land here. Compatibility stays checked, the running total stays current, and you can send one to a local shop or share it with whoever keeps telling you your chainline is wrong.
- 1Add your bike. Frame, fork, shock, travel. This is the part that makes every number after it specific to you rather than generic.
- 2Take the recommended pressures, set them, equalise the chambers, and go measure your sag. The target band is set by how you ride, not by what the fork is called.
- 3Log it. Then change one thing at a time and log that too. Two months in, the log is worth more than the calculator.
