You can adjust the resistance unit position
in 4 patterns to get the best tire contact to
the drive roller for maximum performance.
Wrong positioning may cause damage to
the bearing and the unit housings.
The best hole combination can be seen
on the below matrix and Fig. E.
To change the pivot position between A
and B, remove both the M8x70 Bolt and
the Base Bracket, change the hole then
tighten them again.
If you don't install the Base Bracket, it
may cause unexpected bad stablity of the
resistance unit.
