A worn bicycle chain can cause poor shifting and in time can even cause excessive wear to the derailleur and rear cogs, causing a much more expensive problem. That's why bike component manufacturers recommend chain replacement at regular wear intervals. The Park Tool CC-3.2 is a go/no-go gauge designed to accurately indicate when a chain reaches 0.5% and 0.75% wear (or "stretch"), the points at which most chain manufacturers suggest replacement. The CC-3.2 is long, accurate, and features permanent measurement markings. The CC-3.2 works on most derailleur chains* from 5 to 12-speed.

  • 5-to-10-speed chains: replace chain at or just before 0.75%
  • 11-to-12-speed chains*: replace at or just before 0.5%
  • Check with manufacturer for specific replacement instructions
  • *Use the CC-4 for SRAM Flattop and SRAM T-Type 12-speed chains
  • Updated to be longer, more accurate and features permanent measurement markings
  • Accurately indicates when a chain reaches 0.5% and 0.75%, the points at which most chain manufacturers suggest replacement

We had an outstanding experience at Cyclerie! We purchased two Aventon e-bikes, and the entire process was exceptional from start to finish. The staff took the time to help us choose the perfect bikes for our needs, recommended all the right accessories, and even installed our bike rack on the car before we left.

I had a terrific experience at Cyclerie! I love the bike I bought and working with Skip was great. He told me about customizing features that are available on the bike if you use the Aventon app.
