Free practical cycling tools

Know what each gear really gives you.

Compare an entire cassette by ratio, rollout and speed. Set your own wheel circumference for a result that matches your bike rather than a generic table.

Gearing

Gear & cassette comparison

Rollout is the distance travelled per crank revolution. Speed is based on your selected cadence.

Use a measured rollout from your bike computer for the most accurate result. This compares mechanical ratios only; wind, gradient and power determine real speed.

Tyre pressure guide

A safe starting point for front and rear pressure based on mass, tyre width and surface.

Ride fuelling plan

Turn duration, effort and temperature into a simple packing list.

Chain wear helper

Choose a conservative checker threshold before expensive parts wear out.

Compatibility reference

How to compare setups

Ratios tell the story; rollout makes it tangible.

A ratio of 1.00 means one wheel turn for every crank turn. The same ratio feels broadly similar on different bikes, while rollout turns it into metres travelled. Compare your lowest gear for steep climbs and your most-used middle gears before changing a cassette.

For a complete setup decision, also check derailleur capacity, freehub standard, chain length and the manufacturer’s compatibility chart.
