This User Manual describes the handling of typical, com-
mercially available gear-shi components for MTB, ATB,
cross and road bikes. Separate instructions are provided
for other components on the CD or on the web pages of the
relevant manufacturer in the Internet. If you have ques-
tions on installation, adjustment, maintenance and opera-
tion, please consult a specialist cycle shop.
If gear-shi components are loose, worn, damaged or
adjusted incorrectly, this poses a risk of injury to the
rider. Have the derailleur gears adjusted at a profes-
sional bike workshop.
• Always contact your specialist cycle shop if the
chain jumps o the chainrings or sprockets when
riding or
• you hear unusual noises or
• you cannot change gears easily or
• the rear derailleur, ont derailleur or other
gear-shi components are loose, damaged or
distorted or
• chain links are defective or worn.
