About this 3D model

My existing chain guide and derailleur only went up to about 42t, so I designed this adjustable chain guide for my 48t chain ring that should work with any chain ring size. You will want to adjust the piece that attaches to your bike as the current one has been customized for my bicycle frame and chain ring position. Zip ties work great for attaching to frames with a flat spot but if you have a round seat post tube you may want to use a pipe clamp. Tested for about 20km of hard trail riding with no dropped chains. More info about my electric bike: http://endless-sphere.com/forums/viewtopic.php?f=28&t=50946
