SRAM's Chain Spotter fits on your seat tube beneath your front derailleur to keep the chain from coming off, which keeps you riding and prevents chain and frame damage, too. It's made of lightweight aluminum and includes all mounting hardware. Just bolt it on and go. No front derailleur fine-tuning needed.
- Prevents chain derailment when shifting to inner ring - Adjustable hose-type clamp fits 1-1/8" to 1-3/8" seat tubes
