Cateye's V2 offers 2.4GHz fully wireless speed and cadence functions from a single chainstay-mounted sensor with an information-packed yet clearly readable display on the head unit.
The buttons are a little stiff, but have a good positive click and are usable with gloves despite their small size.
It’s a simple and quick process from mounting, set-up through to using.
Aside from logging data for later download, this has everything you could want from a computer for real everyday performance riding.
We tried all sorts to block the unit with interference, and only a JR 2.4GHz transmitter (for radio control helicopters) could cause the occasional stutter.
