6 converters & gearing-guides on Convert.bike.
How fast you go on a bike is not down to one thing — it is the product of three: how quickly you turn the pedals (cadence), how big a gear you are pushing (gearing), and how far your wheel rolls in one turn (wheel size). Get all three working together and a relaxed-looking spin can carry you along a

It is also one of the easiest things to work out yourself: you need nothing more than the ability to count teeth and do a little division. Once you c

Meanwhile "26-inch", "27.5", "650b" and a tangle of French and inch markings on tyre sidewalls leave plenty of r
Read more →If you have ever tried to compare two bikes, or work out whether a new cassette will give you an easier climbing gear, you will quickly bump into three overlapping ideas: gear ratio, gear inches, and development (sometimes called metres of development or roll-out). They all describe the same underly
Read more →Few things in cycling cause as much head-scratching as tyre sizing. Pick up three tyres from three different decades and you might find one labelled 700x28c, another 27 x 1 1/4, and a third simply 28-622 — and depending on which numbers you trust, you could end up with a tyre that physically will no
