As our thirst for information on the bike grows by the year Topeak have come through with the Dual wireless computer for both speed and cadence.  These technologies are not new together, but what was instantly obvious upon opening the package was the ease in what this unit was going to be operated.  The single button function takes all of the usual fuss out of scrolling through info on the fly and the wide screen fly I found was brilliant being able to display four functions at once.  Not only could you basically have the info you wanted displayed constantly but the characters are much larger on the display than other brands I have used which I really liked.
Topeak used great logic when designing the mounting hardware, the bracket is of a central mounting design and positions the computer right in front of the stem and gives you 100% of your bar surface area for riding! 
Functions are numerous and mostly relevant including:

� Current Speed
� Average Speed
� Max Speed
� Trip Distance
� Odometer
� Ride Time
� Total Time
� Current Temp
� Low Battery Indicator
� 12/24 hr Clock
� Trip Time
� Current Cadence (RPM)
� Average Cadence (RPM)
� Max Cadence (RPM)
� Speed Pacer Indicator
� Bike 1 and Bike 2

Priced at $199 Nzd the V16 is very competitive being the only unit we could find under $200 in this category.
