Adjustable Bicycle Chain Guide
thingiverse
To enhance your bicycle's performance, print chain guide.stl, chain guide (mirrored).stl, and chain guide2.stl. For durability, reduce infill to 60% but increase perimeters and top/bottom layers to 4-5. Visit a hardware store for compatible M4x25 screws and nuts, as well as two wood screws about 35-40mm long. Assemble the pieces visually, then secure with zip ties or pipe clamps. Alternatively, use chain guide (thinner).stl for a slimmer design. This customizable chain guide has been tested for 20km of intense trail riding without dropped chains.
