CS gearing calculator!

We’ve added a calculator to the “cycle speedway gearing” page (on the “articles” menu), click here to try it!

If you have a tyre that’s not listed in the buttons (use them to set the tyre size and name) please let us know the diameter when inflated, and we’ll add it.

Remember, the important numbers are gear inches (how far does your bike travel for one full turn of the pedals?) and ‘relative to standard’ (will this be harder or easier for gating and top speed?)
