Gearing
For integrated shifters on racing bicycles, the gear can be read by the computer: Shimano's Flight Deck and Campagnolo's ErgoBrain work with their respective systems to detect the gearing. This allows indirect measurement of cadence. These systems do not have sensors on the crankset or cassette to determine what gear the bicycle is in. They work exclusively with the shifters, which may result in misleading information. Instead of knowing what gear the bicycle is in, they rely on sensing when the cyclist changes gears using sensors in the shifters. If the gear change doesn't actually happen, or the computer's sensors are too sensitive (e.g.: when braking with STI-style shifters), the information displayed is not accurate.

Famous quotes containing the word gearing:
“There’s no telling what might have happened to our defense budget if Saddam Hussein hadn’t invaded Kuwait that August and set everyone gearing up for World War II½. Can we count on Saddam Hussein to come along every year and resolve our defense-policy debates? Given the history of the Middle East, it’s possible.”
