Cateye's Velo is a reliable wireless computer. The sensor attaches with a rubber ring, has a shaped rubber foot for security and the head mount is zip-tied, making set up simplicity itself whatever your bar shape. The massive main digit of the two-line display is easy to see and scrolling through the seven essential speed, distance and time functions is very easy via the single big button/bar below the screen no matter how cold your fingers, thick your gloves or rough the bike path.
