A perfect complement to the AeroCoach ARC or Aten 1x chainrings for riders who have non-removable front derailleur hangers, or who race on very broken road surfaces, the aluminium AeroCoach AffixR chain guide is an aerodynamic alternative to a front derailleur!
AffixR chain guides are made of aluminium and have a range of vertical and horizontal adjustment with just a single adjustment bolt. It fits all standard braze on mounts and is suitable for chainrings from 50t to upwards of 60t.
1x specific chainrings should be used with the AffixR, not standard shiftable chainrings (eg. Shimano/SRAM). Please note, due to the extreme chainring shape an AffixR is not suitable for Q Rings or OSymetric rings, but will work with the subtle shape of an ARC or Aten ring.
Replacing a front derailleur with an AeroCoach AffixR will save 2-3.5w at 45kph, and only incurs a ~1w penalty over no hanger.
