A perfect complement to the AeroCoach ARC chainring for riders who have non removable front derailleur hangers or who race on very broken road surfaces, the AeroCoach Affix chain guide is an aerodynamic alternative to a front derailleur!

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.
