Sprocket is the precise bike gear calculator built for road, gravel, MTB, and touring cyclists. — KEY FEATURES — • Live calculations: enter front chainring teeth, rear cog teeth, cadence (40–200 rpm), and wheel size — gear ratio, gain ratio, gear inches, and speed in km/h or mph update instantly as you type. • Six wheel sizes: 700c, 650b/27.5", 29", 26", 24", and 20" — covers road, gravel, mountain, and kids' bikes. • 10 built-in cassette presets: 11-speed road, gravel, and endurance; 10-speed touring and racing; 12-speed MTB wide-range — full cog-by-cog listings for every preset. • Custom cassettes: add any cassette by entering a comma-separated cog sequence; the app auto-detects speed count and cog range. • Saved bike setups: store named setups with chainring, cassette, wheel size, and target cadence. Each setup shows top speed, hardest gear ratio, gear inches, and easiest gear at a glance — perfect for comparing builds before swapping parts. • 5 seeded setups to explore: Road Racer, Gravel Adventure, Trail MTB, Sprint Track, and Loaded Tourer — realistic starting points for every riding style. • mph / km/h toggle: flip speed units anywhere in the app without re-entering data. • Fully offline: no account, no ads, no network connection ever required. Your data lives on-device. Whether you're speccing a new build, planning a gear swap, or nerding out on drivetrain math, Sprocket gives you the numbers you need — instantly and accurately. — Sprocket Bike Gears PREMIUM — Sprocket Premium unlocks the full app experience: unlimited saved bike setups, all 10 cassette presets plus custom cassette entry, and every calculation metric (gear ratio, gain ratio, gear inches, and speed) — completely ad-free and 100% offline.
