The wireless Velomann comes with an altitude function – there’s a tiny barometer in here that works it out from air pressure – so you can clock the amount of climbing you do.
As well as a running total, you get your current and max altitudes and also a gradient reading, although that can lag by a few seconds.
There are 20 functions in all, including temperature, and you get five labelled measurements on the display at any one time so you don’t need to toggle endlessly through the various screens.
Some of the figures are fairly small but we had no real problems with legibility. We had no interference to the analogue signal from other equipment, despite our best efforts.
You can set it up for two different bikes with the addition of a second speed sensor (£9.99). A similar model, the V1.20HR (£60.99), swaps the altitude measurements for heart rate.
