Prevent Expensive Drivetrain Wear
The ParkTool CC-2 Chain Checker brings a critical preventative maintenance advantage to your workshop. For instance, riding with a worn, stretched chain rapidly accelerates wear on your expensive cassette cogs and chainrings. Consequently, delaying a simple chain replacement eventually forces you to buy a completely new drivetrain. By using this precise indicator regularly, you can pinpoint the exact moment your chain begins to degrade. Ultimately, this habit keeps your shifting crisp and saves you hundreds of dollars in replacement parts.
Precise Swing-Arm Measurement System
Checking your daily chain wear is exceptionally straightforward with this interactive dial gauge. To get a reading, you simply insert the tool’s two underside pins into two links of your chain. Next, you lightly press the swing-arm gauge until the pins push firmly against the rollers. The tool then displays the exact percentage of wear in the clear gauge window. Because this system measures physical chain pin movement, it eliminates the guesswork associated with basic drop-in indicators.
Broad Multi-Speed Chain Compatibility
This versatile diagnostic tool covers a massive range of modern bicycle drivetrains. Specifically, the gauge scales are calibrated for everything from classic single-speed chains up to modern 12-speed systems. For example, you should replace 5-to-10 speed chains when the gauge reaches 0.75% wear. Meanwhile, high-performance 11-to-12 speed chains require replacement at or just before 0.5% wear because of their tighter tolerances. However, please note that you should use the specialized ParkTool CC-4.2 for SRAM Flattop and T-Type 12-speed chains.
