Fouriers showed us their new narrow/wide chainring design, featuring unique CNCed micro channels intended to help evacuate mud and dirt.

The company also sells a wide-range add-on cog solution which includes this 16t replacement cog (used to bridge the gap when removing the 15 or 17t from the cassette to make room for the larger 40/42 cog). The 16t features 3 chain pick-up points meant to provide smoother shifting across the modified cassette.
