CC-3.2 Chain Wear Indicator
A worn chain shifts poorly and wears sprockets at an
accelerated rate. The CC-3.2 is a "go/no-go" gauge de-
signed to accurately indicate when a chain reaches .5%
and .75% wear, the points at which most manufacturers
suggest replacement (contact the chain manufacturer
for specific replacement recommendations).
Instructions:
One side of the CC-3.2 is used to check for chain
wear at the .5% level; the other side is used to check
for chain wear at the .75% level. Select correct side
and lower CC-3.2 onto chain. If gauge tip fits com-
pletely into chain link (Figure 1), the chain is worn
and should be replaced. If gauge tip does not fit into
link (Figure 2), the chain is not worn and does not re-
quire replacement.
CL-1 Synthetic Blend Chain Lube with PTFE
Using a proprietary blend of oils and PTFE, CL-1 works
great in wet or dry conditions. It penetrates, reduces
friction, prolongs component life, displaces moisture,
and protects parts from rust and corrosion. Apply a
drop to the inside of each chain link; then wipe off ex-
cess with a rag. Also works great on brake and derail-
leur pivot points.
CM-5.2 Cyclone Chain Scrubber
The Cyclone Chain Scrubber cleans bicycle chains
quickly, easily, and effectively without the hassle and
mess of removing the chain from the bike. Regular use
improves shifting performance and extends the life of
the chain and other drive train parts.
