AeroCoach Affix 1x aero chain guide

Description

The injection molded Affix aero chain guide has a an angular range of adjustment for chain-line and fits all standard braze on mounts. Suitable for large chainrings (58t+) as well as standard 50-54t rings. Comes with bolts and mounting instructions. We recommend the use of 1x specific chainrings , not the use of standard shiftable chainrings (eg. Shimano/SRAM). Please note, due to the extreme chainring shape an Affix is not suitable for Q Rings or Ossymetric rings, but will work with the shape of an ARC ring.

Replacing a front derailleur with an AeroCoach Affix chain guide will save 2-3.5w, and only incurs a 1w penalty over no hanger.
