When I was a marathon runner, I relied heavily on my GPS watch. That watch could do it all, it gave me my pace, time, location, pedometer, even my heart rate. It was like having a little computer on my arm and anything I needed or wanted to know could be gleaned from that little watch.

When I switched over to biking instead of running, I still wore the watch but honestly it turned into a bulky timepiece that wasn’t much good for cycling. That’s when I started looking for an alternative. Cycling computers were most definitely the best thing I found. In specific, the Sigma Rox 8.0 bike computer can show you absolutely anything you want to know from altitude and temperature to heart rate and calorie burning calculator. It also is water tight, runs on batteries, and can be plugged into your computer. I could even stop wearing my watch because it told me the date, time, and had an alarm.

For someone who is transferring over from being an avid runner and having all of your mileage stats at your fingertips, a cycling computer is definitely one of the biggest must have cycling accessories. I’m surprised this thing doesn’t make me a carb-loaded breakfast as well.
