Specialized Rip Rock chain guide

Two versions of an improved chain guide for a Specialized Rip Rock. My son's bike often lost the chain when he was riding the bike, and I couldn't get the gap between the stock chain guide and chain small enough to prevent this. These two chain guide designs are intended to allow easier adjustment of this gap. It uses the stock clamp, screw, and post. I ended up using the REV2 version, seems to work well.

Both .3mf and .stl files are included.

I included the Solidworks 2017 .prt files for your remixing fun.
