  • Great tool for the bicycle tool box.
I ride bikes a lot, but never considered how important the chain was. Now it is easy to check my chains on all my bicycles to see if the chain needs replacement. If you are having a stretched chain on your bicycle too long it will damage the chain rings and other components making you bike shift not so good. Easy to use and you can trust the great products from Park Tool. Well made and a great part of your bicycle maintenance program. ... show more

Works as designed!

  • Perfect checker
Not much to it but it does work very well. Drivetrain was running sluggish and knew I had to check it out myself. This immediately told me I was over 1inch in terms of a chain stretch without having to double guess. Put a new chain on and checked out the new one to ensure accuracy. Don't skimp out on an essential tool here. ... show more
