CHECK FOR CHAIN WEAR
Shift into neutral, pull up the upper stretch
of the chain with a force of 10 - 15 kg (see
figure). Measure the length of 18 links on
the lower stretch of the chain. If the length
is
*
272 mm, replace the chain. Chains
do not always wear evenly. For this reason
it is important that the measurement is taken
at different points along the chain.
When fitting a new chain, be sure to re-
place the chainring and sprocket as well.
New chains wear more quickly if fitted on
old and worn sprockets. After replacing
the chain, adjust its tension as described
on page 69.
