17 paź 2024 · Our bike gear calculator can show the ratios for the range of chainrings and cogs teeth so that you can check your bike gear ratios and gear inches in different settings: Choose the minimal value of the teeth in the chainring. Let's say it's 42. Pick the maximum number, 48, for example.
The following instructions aim to assist you in effectively using our gear ratios calculator, ensuring a more seamless and informed experience. Count the number of teeth on the front cog of your bicycle, and select this value in the picker labeled chainrings teeth.
28 cze 2015 · Tight gear spacing – lots of gears with 10 to 15% of gear ratio difference, so that appropriate gear can be selected depending on riding conditions. Bicycles usually have from one to three front chainrings, with relatively large gap of teeth number between them.
It's calculated by dividing the number of teeth on the front cog by the number of teeth on the rear cog. Gear ratios can be calculated from the following formula, where CT stands for chainring teeth, ST for sprocket teeth, and GR for gear ratios.
The ratios are 0.40 for the Mountain Drive, 1.65 for the Speed Drive, and 2.50 for the High Speed Drive. Peter Heinle has an Excel spreadsheet online with the tooth counts of a large number of 10-through 13-speed cassettes
Gear ratio is the relationship between the number of teeth on the front chainring and the rear sprocket. It's calculated using this simple formula: Gear Ratio = (Front Chainring Teeth) ÷ (Rear Sprocket Teeth) For example: Gear Ratio = 50 ÷ 25 = 2.00.
