Use an easier gear (1 is the easiest) on hills or when you’re riding into the wind. Use a harder gear (7 is the hardest) on flats or if the wind is blowing from behind. When you shift, keep pedalling but ease up on the pedals, especially on hills. If you are pushing hard or if you stop pedalling completely, the chain can skip or fall off.

  • Page 68: Adjusting The Chain Tension

    Make sure the brake discs and brake pads are never in contact with any oil or other lubricants. Oil or lubricants affect the brake's functioning and can lead to dangerous situations. 5.2 ADJUSTING THE CHAIN TENSION TOOLS/MATERIALS REQUIRED Knaap toolkit Put your bike on a bike stand. The wheels should be up in the air; otherwise it is difficult to tighten the bike chain. KNAAP BIKES...
  • Page 69 Carefully loosen the axle nuts that are holding your rear wheel onto the bike. This loosens the rear wheel, allowing you to adjust the tension on the chain. Carefully pull back on the rear wheel. This increases the tension on the chain. Check whether the tension is correct: The maximum play allowed when moving the chain is 1 cm or half an inch in either direction.

    Make sure that the bike is clean and that the drive chain is degreased. See section 5.1 Cleaning the bike. LUBRICATION INSTRUCTION POINT Put a drop of lubricant on each link, while you backpedal slowly for a few rotations. Chain Wipe off the excess of lubricant. TIP: Not wiping off the excess of lubricant attracts more dirt to the chain. Never use motor oil. KNAAP BIKES...
  • Page 71 LUBRICATION INSTRUCTION POINT Rear shift cable: Shift the gears until the chain is on the largest sprocket, and then stop the wheel from rotating. Shift your shifter all the way in the opposite direction, as if you were going to shift to the smallest sprocket. The rear derailleur should now be stuck on the largest sprocket. This will give you enough slack to fully release the cable from the frame. Pull the upper section of the outer cable down leaving a section of inner cable exposed.
