2.15 Check the chain tube lengths
Note: If tightening the plastic clips onto the pulley plate, be careful not to over-tighten the bolts; it is possible
to damage the plastic clips if you do. These clips are pre tightened at the factory and are designed to allow
some movement of the top front and rear tubes for correct chain alignment when in different gears.
Check for clearance
between the chain tubes
and the front chainset. If
the top or bottom chain
tube at the front is too
long, shorten them by
cutting the tube at the
front end to the required
length with a sharp knife.
