The first ever cycle computer specifically designed for commuters and those who ride for transportation, errands, and utility. Critical trip details make the CatEye Commuter Computer the best option for making your rides stress free. Estimated Time of Arrival, clock, temperature, and back light help you stay on schedule. The new larger font size makes it even easier to read trip details with a quick glance. Carbon Offset information is included along with standard computer features so you will not only feel better from the ride, youll feel better about the ride. The Carbon Offsets are computed by using a fixed 150gkm or 240gmile figure and multiplying it by the distance ridden. It tracks it in real time and shows day to day, week to week, month to month and total carbon saved. The innovative FlexTight bracket mounts quickly, securely and without tools to virtually any handlebar or stem. The tool free speed sensor mounts effortlessly to any standard fork.
