The device is equipped with an electronic gear shift that provides committed athletes
with a more realistic biking experience on the pre-programmed circuits. The 28 available
speeds enable a linear shifting over the whole performance domain of the bike in road, off-road and triathlon biking.
The distance travelled per pedal revolution in the highest gear is
. This corresponds to a gear ratio of
with a
.
The distance travelled per pedal revolution in the lowest gear is
. This corresponds to a gear ratio of
with a
.
