At what percentage stretch should I replace my SRAM chain?

SRAM recommends replacing chains at 0.8% stretch. This is the threshold the TL-CNTL-WEAR-A1 is calibrated to. Replacing at this point prevents accelerated cassette wear.

Does this work with SRAM 12-speed Flattop chains?

Yes - the SRAM Chain Wear Checker is compatible with all SRAM chain models including Hard Chrome 12-speed Flattop variants like the PC-Red E1.

How often should I check my chain wear in India?

Every 500 km in dusty or wet conditions. Indian road grit is a significant abrasive - more frequent checking is recommended than the typical 1000 km interval advised for European riding conditions.
