If the largest or smallest sprocket on your bike’s cassette is different from the largest or smallest sprocket on your Zwift Hub’s cassette, you may need to shorten or lengthen your chain for optimal performance.Strava, the largest sports community in the world, with over 99 million athletes, today announced a three-year partnership with the Tour de France and the Tour de France Femmes avec Zwift. Note that the number of teeth on your cassette is also important to pay attention to. If you require a different number of speeds, gear ranges, or use SRAM XD / XDR, you can order your Zwift Hub with no cassette, no sweat. Zwift Hub can be ordered with an 8, 9, 10, 11 or 12-speed cassette. For example, if you have 10 cogs on the rear of your bike, you’ll need the 10-speed cassette option. To know which cassette option you need, count the number of cogs on your rear wheel. Zwift Hub comes with a preinstalled cassette to match your bike to ensure they’ll work seamlessly together. Together the group of them at the center of your bike’s back wheel is called a cassette. You might call them cogs, sprockets or gears.
