Example<\/h2><\/div>\r\n\r\n<\/p>\n<p><strong>Example:<\/strong> a road cyclist rides a 50-tooth chainring with a 14-tooth rear cog, 700\u00d725c tyres (wheel circumference 2111 mm) and holds a cadence of 90 rpm.<\/p>\n<p>\\[ i = \\frac{50}{14} = 3.57 \\]<\/p>\n<p>\\[ dev = 3.57 \\times 2.111\\,\\text{m} = 7.54\\,\\text{m} \\]<\/p>\n<p>\\[ v = \\frac{7.54 \\times 90 \\times 60}{1000} = 40.7\\,\\text{km\/h} \\]<\/p>\n<p><strong>Result:<\/strong> the bike travels at about 40.7 km\/h (25.3 mph), covering 7.54 m (296.8 inches) per pedal revolution with a gear ratio of 3.57.<\/p>\n<p>\n\r\n<\/section>\n<h2>How to Use the Cycling Gear Speed Calculator<\/h2>\n<ol>\n<li>Enter the number of teeth on your front <strong>Chainring teeth<\/strong> field (for example 50 for a standard big ring, 34 for a compact inner ring).<\/li>\n<li>Enter the cog size in <strong>Rear sprocket teeth<\/strong> \u2014 pick the sprocket you actually ride in that situation, e.g. 14.<\/li>\n<li>Fill in <strong>Wheel circumference<\/strong> and choose the matching unit (mm, cm, m or inch). A 700\u00d725c road tyre is about 2111 mm; a 29\u2033 MTB tyre is about 2288 mm.<\/li>\n<li>Enter your <strong>Cadence<\/strong> in rpm \u2014 the number of pedal revolutions per minute you want to sustain.<\/li>\n<li>Read your results: speed in km\/h and mph, distance per pedal revolution in metres and inches, and the gear ratio.<\/li>\n<\/ol>\n<h2>What the Calculation Means<\/h2>\n<p>The calculator answers a simple question: if my legs turn the cranks at a given rate in a given gear, how fast does the bike move? The answer is fixed entirely by the drivetrain geometry \u2014 it does not depend on fitness, wind or terrain. That makes it a useful tool for comparing gears on paper before you ever ride them.<\/p>\n<p>The <strong>gear ratio<\/strong> \\(i = z_1 \/ z_2\\) tells you how many times the rear wheel rotates for one turn of the pedals. A ratio of 3.57 means one pedal revolution spins the wheel 3.57 times. Higher ratios (bigger chainring or smaller cog) give more speed per pedal stroke but require more force; lower ratios make pedalling easier but slower \u2014 that is why you shift down for hills.<\/p>\n<p>The <strong>distance per pedal revolution<\/strong> (sometimes called \u201cdevelopment\u201d, especially when measured in metres) shows how much ground one pedal stroke covers. European track and cyclo-cross racers often think in gear inches, the imperial equivalent shown in the results. At the same cadence, a bigger development simply means a higher speed.<\/p>\n<p>The final <strong>speed<\/strong> is the development multiplied by your cadence and converted to an hourly figure. To put the numbers in context: 40.7 km\/h on the flat is a hard group-ride pace, 25\u201330 km\/h is a comfortable cruising speed for a trained cyclist, and anything under 15 km\/h in a low gear typically means you are climbing. If you want to know how much power you need to actually hold that speed, try our <a href=\"https:\/\/wpcalc.com\/en\/beauty\/cycling-ftp-power-zones-calculator\/\">Cycling Power Zones calculator<\/a>.<\/p>\n<h2>Common Wheel Circumferences<\/h2>\n<table>\n<thead>\n<tr>\n<th>Tyre size<\/th>\n<th>Typical circumference (mm)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>700\u00d723c road<\/td>\n<td>2096<\/td>\n<\/tr>\n<tr>\n<td>700\u00d725c road<\/td>\n<td>2111<\/td>\n<\/tr>\n<tr>\n<td>700\u00d728c road<\/td>\n<td>2136<\/td>\n<\/tr>\n<tr>\n<td>26\u2033 MTB<\/td>\n<td>2075<\/td>\n<\/tr>\n<tr>\n<td>29\u2033 MTB<\/td>\n<td>2288<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>For best accuracy, measure your own wheel: roll the bike one full wheel revolution with the valve at the bottom, mark the start and end points, and measure the distance. Tyre pressure, width and tread all affect the true value.<\/p>\n<h2>Assumptions, Limitations and Tips<\/h2>\n<ul>\n<li><strong>Zero slip:<\/strong> the calculation assumes a perfectly efficient, non-slipping drivetrain. In reality a little chain friction exists, but it barely changes speed.<\/li>\n<li><strong>It ignores resistance:<\/strong> the result is the speed your gear forces at that cadence, not the speed you can sustain. Wind, gradient, rolling resistance and your available power decide what actually happens \u2014 a 40 km\/h gear is useless on a 10% climb if you cannot turn the cranks.<\/li>\n<li><strong>Cadence matters as much as gearing:<\/strong> doubling your cadence doubles the speed in the same gear. Most road riders sit at 80\u2013100 rpm; compare gears at a realistic cadence rather than a number you could only hold for seconds.<\/p>\n<li><strong>Internal gear hubs and belt drives:<\/strong> enter the equivalent chainring\/sprocket combination; for hub gears, calculate each hub ratio separately or use the effective development if the manufacturer publishes it.<\/li>\n<li><strong>Use it for gear planning:<\/strong> before buying a new cassette or chainring, check the extremes \u2014 your lowest gear should give a development you can spin up the steepest climb you ride, and your highest should be low enough that you can still pedal downhill without spinning out.<\/li>\n<\/ul>\n<p>Once you know what speed a gear produces, the next questions are about your body: can you hold that effort, and for how long?
