Checking and readjusting
Check the headset for play by placing your fingers around the upper head tube race. Bring your weight to bear on the saddle, pull the front brakes with your other hand and push the URBAN JUNGLE bike firmly back and forth with the wheel
remaining on the ground (a). If the bearing has play, you will feel the upper head tube race moving in jerks relative to the lower head tube race visible as a small gap in between the head tube races.
To check the bearing for ease of running, lift the frame until the front wheel is suspended in the air (b). The handlebars should turn from far left to far right without feeling roughness or tightness at any point. With a gentle tap on the handlebars the fork should turn easily from the middle position.
If you face any problems during the test, contact your URBAN JUNGLE dealer.
SAFETY INSTRUCTIONS
Adjusting the headset requires a certain amount of experience and should therefore be left to your URBAN JUNGLE dealer.
CONVENTIONAL HEADSETS
The adjustment tolerance between there being play in the bearings and them being set too tight is very small. The bearing can easily be damaged. If you want to try it nevertheless, you need two large and flat open-end wrenches (c). Ask your URBAN JUNGLE dealer for advice.
Release the top lock nut and turn the head cup below clockwise without tightening it. Fix the lower head cup and retighten the lock nut.
WARNING
A too tight adjustment can destroy the bearings and affect the riding characteristics.
