This is an e*thirteen LG1+ chainguide in black. A chainguide bolts to the frame around the chainring and keeps the chain from coming off in rough terrain.

What it's for

A full chainguide holds the chain on a single chainring from above and below, and usually adds a bash guard to protect the ring from rock strikes. It is meant for downhill and other hard riding where a clutch derailleur alone is not enough.

Compatibility

• Chainring size: e*thirteen made the first generation LG1+ in 32-36t and 36-40t ranges. The SKU on this item points to the 36 tooth range, but check the package for the exact range.
• Frame mount: your frame needs chainguide tabs or another mount that matches the guide. Check the package for the mount standard.
• How to check yours: Look for three threaded tabs around the bottom bracket shell on the drive side, and count the teeth on your chainring.

Care and service

• Parts and manual: e*thirteen support hosts the LG1+ user manual and a service parts diagram, and still sells replacement bash guards and sliders for first generation LG1+ guides.
