Bicycle Chain Keeper 2x or 3x

Optimized for 28.6mm seat tube, but flexible enough to use on larger seat posts. Requires a zip tie and super glue for assembly.

Designed to mimic old K-edge chain keepers; the print sits up next to your granny gear and prevents a chain drop when going for high to low chainring. 

Printed in PETG with 5 walls and 25% infill. Comes to a light 7g. No supports necessary. Unsure if PLA since it's less flexible than PETG.

Installation instructions:

-Place the mount on the seat tube near your small chainring (tighten zip tie enough to secure it, but allow for some adjustment

-Attach the triangle like chain keeper and slide it along the mount until it is about 2/3mm from the small chainring

-Shift your front derailleur into the low gear and adjust so that chain keeper doesn't interfere with the derailleur cage

-Mark where you want the chain keeper to rest, remove the triangle like portion, apply super glue, and attach to the mount at your desired distance.
