If the wired cycling computers of the ’90s left lasting negative impressions, then CatEye’s Stealth 10 GPS is here to change that. Instead of fragile wires, the Stealth uses GPS sensors to provide accurate speed and distance readings. That means no more wheel calibration, so you can swap from multiple bikes with ease, and it enables a clean installation on most handlebars. The CatEye Stealth 10 GPS uses a USB cord to charge its lithium-ion battery for up to 60 hours of use. It comes with a handlebar/stem mount and has a 12/24hr clock.
