as far as i know is the 160/180 adapter you have only a mount four the breaks you have, if you have mtb brakes you don’t need any for 160 breaks. what you need is a standart +20mm adapter(160mm to 180mm) front and the adapter is on the top of it. I am mainly using mtb breaks so could be wrong.

I was bringin sandals with me and hike-off with them

I once hiked onto a mountain barefoot because of a bet with a friend, it took me 3 1/2 hours untl I have reached the summit.
