The ROX 8.1 is equipped with a new function:
The PERFORMANCE MEASUREMENT.
The calculation of performance is based on
a formula lodged within the ROX 8.1.
Here the calculated performance is the power
that is needed to move the bike, not the power
acting on the pedals.
To evaluate performance, several values have
to be entered in the ROX 8.1: Weight of the
bike and the cyclist, bike type and position of
the cyclist on the bike, cyclist's height and
shoulder width.

6 USInG ThE SIGMA ROX 8.1

In this chapter we explain all the functionalities of the SIGMA ROX 8.1 so that you can ride efficient.

6.1 FAvORITES A AnD B

The favorites A and B are two sections where
you can program the functions that are most
important to you. Both favorites come with
certain preset functions, but these can be
changed at any time. A total of 10 functions
can be stored in each of the two favorites.
The performance values shown are
approximate figures and are calculated
assuming an average wind speed and
average road quality.
The performance is calculated precisely on
a slope, whereas average values are used
for calculation on a level route.
This means you have up to 15 functions
(speed, current altitude, current pulse,
current cadence and 10 functions from the
favorites) that you can easily access during
the ride.
