BIKE SPEED, WEIGHT, AERODYNAMICS AND TIRE WIDTH CALCULATOR

This calculator uses a formula derived from data collected from real world riding experiences. This calculator allows you to estimate the impact that bike weight, aerobars, tire width, distance of the ride and wattage have on speed.

For best comparisons, change just one thing at a time to see how much difference it will make on your speed!

EXAMPLE: Fill in all fields with your current bike's setup and weight, and your usual riding distances and watts (NOT SURE? Just fill out 15 for distance and 115 for watts). Then change just the bike weight, and see how much your speed will change. Or, change just the tire width and so on...
