YT Jeffsy Bike Chain Guide

thingiverse

This is an upper chain guide that fit on a first generation YT jeffsy 27.5 (pre 2019 I think). I cannot confirm if this works on the 29" version of the second generation frames (2019+). This mounts by bolting up to the E-type front derailleur holes. I sized this to work with a 28t chain ring, but I think it will clear at least a 30, maybe a 32. You could adjust the model or scale it a bit to match a larger ring. The design is inspired of a similar model, but I started from scratch and reshaped the whole thing. Mine is printed with SLS nylon, but I think FFF could also make this work.
