Sette Quantum-X Cyclo-computer Version 2.0
Completely redesigned and updated, the Quantum X cyclo-computer features a stylish compact body with two easy-to-use oversized buttons to allow for function adjustments on the fly. The oversize digital display allows legibility at a glance. Installs in minutes to any bike with few tools and will accept multiple wheel-size settings.
I enjoyed this for almost two summers. I got about 3-400 miles out of it before it stopped working. It's not a necessity but I really wanted to know how many miles I rode on average commuting and in the mountains. I now have a reference b/c of this, it's good for the price.
This unit is a very basic computer that is great for keeping track of my miles and speed on the trails.
