Using the parking brake switch
The front hydraulic brake levers have a parking brake switch. To operate the switch, hold in the brake
lever as hard as you can and flip the switch. The switch holds the brake lever in place, which holds the
rotor in place and prevents Juggernaut from moving when parked. The parking brake is very useful when
parking on angle. REMEMBER to switch off the parking brake before riding.
NOTE: Riding with the parking brake engaged produces significant wear on the brake pads leading to a
decrease in brake pad life and stopping power. Warranty DOES NOT cover replacement brake pads.
Using the microSHIFT derailleur clutch
All 2020 models use the microSHIFT Advent derailleur system
with built-in clutch to maintain better chain tension on the
return track when off-roading (bumpy riding). It has the
significant advantage of maintaining better gear engagement
and
limiting “chain suck” due to changing weather conditions.
For these reasons, the team at Rungu strongly recommend
the clutch switched on when riding in all conditions.
To switch on the
clutch, move the
switch on the side of the derailleur UP so that it aligns with the
white dot. You can tell that the clutch is enabled by pushing the
lower derailleur pulley
forward, you should
encounter significant
force to move the
pulley. To disable the
clutch (for wheel
removal), move the
switch on the side of
the derailleur down so
that it aligns with the white circle. You can tell when the
clutch is disabled by pushing forward on the lower pulley.
You will encounter minimal resistance to pivot the lower
section of the derailleur.
