AeroCoach Affix 1x aero chain guide
The injection moulded Affix has a an angular range of adjustment for chainline and fits all standard braze on mounts. Suitable for large chainrings (58t+) as well as standard 50-54t rings. Comes with bolt and mounting instructions. 1x specific chainrings are recommended, 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 OSymetric rings, but will work with the shape of an ARC ring.
Replacing a front derailleur with an AeroCoach Affix will save 2-3.5w, and only incurs a 1w penalty over no hanger.
