Park SBS-3 Socket And Bit Set

Description

Don’t let a worn chain accelerate drivetrain wear.

The Park Tool CC 3.2 is an extremely easy ‘Go’, ‘No-Go’ gauge that will tell you when you need to replace your chain. Accurately indicates when a chain reaches .5% and .75% wear.

• 9 and 10-speed chains will need to be replaced when the .75% side fits.
• 11 and 12-speed chains should be replaced when the .5% side fits.

Please see photos for further instructions.

Please note: Failure to replace a worn chain will accelerate wear on other components, once this happens, you may need to replace your cassette as well.
