Sigma ROX 8.1 Multi-Function Bike Computer - White In addition to classic cycling functions, the Rox 8.1 can measure altitude, terrain gradient, pulse, temperature, distance traveled with one turn of the crank and calculate the power output. The Sigma Transmission System (STS) can transmit readings simultaneously from three sensors (speed, pulse and cadence sensors). Short data transfer times ensure faster updating of the displayed data. Short transfer time together with a new, more efficient sleep mode extend battery life. The bike computer is waterproof. It can be used for 2 wheels (2 adjustable wheel circuits) with automatic 2nd wheel detection. Bright, clear and backlit display with zoom function. If necessary, values can be programmed (directly from the cycling computer or via a PC) that will be displayed during the ride (up to 10 functions can be selected) without the need to click through to them. This way you can set 2 groups of favorites. The memory holds records from 7 trips.
