Bicycle Gear Ratio Chart: Compare Easier Climbing and Faster Gears
Use the bicycle gear ratio chart to compare chainrings, cogs, climbing gears, faster gears, and related gear inches/meters tools.
Bike Calculator
Bicycle Gear Meters: Understand Development and Rollout
Use bicycle gear meters of development to compare how far your bike travels per crank revolution across chainrings, cogs, and wheel sizes.
Bike Saddle Height Calculator: Set a Safe Starting Height
Use the bike saddle height calculator to set a starting height, then check knee bend, hip rocking, reach, cleat position, and ride comfort.
Crank Length Calculator: Find a Safer Starting Size
Use the crank length calculator as a starting point, then check fit, knee comfort, hip angle, ground clearance, and bike type before swapping cranks.
Mountain Bike Tyre Pressure Calculator: Start With Grip and Control
Use the mountain bike tyre pressure calculator as a starting point, then adjust for rider weight, tire volume, tubeless setup, terrain, rim protection, and conditions.
Bike Speed, Distance, and Time Calculator: Plan Rides More Clearly
Use the bike speed, distance, and time calculator to estimate ride duration, average speed, route distance, pacing, stops, and realistic arrival windows.
Bicycle Gear Inches Calculator: Compare Gears Across Wheel Sizes
Use gear inches to compare chainrings, cogs, and wheel sizes, then connect the result to cadence, rollout, climbing, and speed.
Bicycle Gear Speed Calculator: Cadence, Tire Size, and Speed
Use the bicycle gear speed calculator to estimate speed from cadence, tire size, chainring, cog, gear ratio, and wheel rollout.
Bike Frame Size Calculator: How to Use the Result
Use the bike frame size calculator to estimate your frame size, then check standover, reach, bike type, geometry, and test-ride fit.
Bike Gear Ratio Calculator: Compare Chainrings, Cogs, Gear Inches, and Speed
Use the bike gear ratio calculator to compare chainrings, cogs, cassette range, cadence, climbing gears, top speed, and drivetrain tradeoffs.
Skid Patch Calculator: Fixed Gear Tire Wear and Gear Choice
Use the skid patch calculator to understand fixed gear tire wear, chainring and cog combinations, rotation points, and safer setup choices.
