A very large display, easy operation, and over 34 functions: the VDO R series GPS bike computer reliably shows cyclists all the important data for their training or tour. In addition to displaying speed, distance, and training time, the intelligent bike computer also provides navigation information and can be paired with compatible e-bikes. A real highlight is the integrated barometric altitude measurement. The high-contrast display is very easy to read, especially while riding, thanks to its 2.4-inch diagonal and extra-large digits. A colorful blue square in the upper right corner of the display enables a new way of presenting training data. When combined with the compatible SIGMA RIDE smartphone app, up to six individual training views can be set with just a few clicks. The VDO R5 GPS is mounted on the handlebars using the included Overclamp Butler, which places the computer centrally above the stem, ensuring a tidy handlebar and even greater readability. The Butler fits handlebars with a diameter of 31.8 to 35 mm. Want to collect even more data from your training or trip, or improve its accuracy? Connect external sensors like speed, heart rate, or cadence sensors to your computer thanks to ANT+ and BLE connectivity. Get going! Now you're in control!
