Take the guesswork out of gearing.
Whether you’re planning a race, building a new bike, swapping chainrings, or just curious about your drivetrain’s limits, Bike Gear Ratio Analyzer gives you real-world insight — instantly.

Enter your chainrings, cassette, wheel size, power, and preferred cadence, and the app calculates:
• Gear ratios
• Speed at any cadence
• Climbing limits based on gradient & power
• Whether a specific hill is rideable at your minimum cadence

Perfect for road cyclists, gravel riders, mountain bikers, triathletes, and mechanics looking to select the right drivetrain before hitting the road or trail.
