WARNING: The above checklist intentionally excludes suggestions about when to repair or
replace bike components. The proper time to repair or replace something is determined by how
often and how hard you use it and is therefore unpredictable. You'll be more likely to notice when
your bike needs service by following the above checklist and by noticing how your bike performs
on a daily basis. When service is required, if you have any doubts about your ability to perform
the proper procedures, visit your nearest authorized Cannondale dealer or service professional.
Incorrect repair of your bike or any of its components and systems may seriously reduce
performance and could lead to injury or death.
