Park Tool CC2 Chain Checker: Check Chain Wear for £26.99
The Park Tool CC2 is a hand gauge for measuring chain wear. We have not used it ourselves. This page collects what Tredz lists and the current price.
Available now: Park Tool CC2 Chain Checker — £26.99 at Tredz, correct at time of writing, 8 October 2026.
What the retailer lists
- How it works: insert the checker’s pins into two chain links, press the swing-arm gauge and read the gauge window.
- Range: reads wear from 0.25% to 1%.
- Why it matters: Tredz notes that 1% wear is enough to affect chainrings and sprockets and let shifting performance deteriorate.
- Compatibility: Tredz lists it as 10-speed compatible. We have not checked it against 11- or 12-speed chains, so confirm with Park Tool before buying for a newer groupset.
Where it fits a triathlete’s winter
The points below are our reading of the listed specs, not test results.
- Wet-weather mileage. Winter riding in grit and rain wears chains faster, so a regular check is cheaper than replacing a worn cassette and chainrings.
- Turbo season. Hours on the indoor trainer count towards chain wear too.
