Rider tools

Dial in your ride

Physics- and sports-science-backed calculators to set up your bike and plan your ride. Sign in and they'll use your garage and weight automatically.

Tyre pressure

Front/rear pressures from your weight, bike/tyre setup, the conditions and the day's weather.

Speed at any cadence, gain ratios for every gear, and a climb-gear check for steep pitches.

Carbs, fluid and sodium per hour for a ride — scaled to its distance, climbing, effort and the heat.

A quick starting saddle height from your inseam and a crank-length suggestion by height and discipline.

These tools give starting points based on established formulas and guidance — adjust to your own body, terrain and feel.
