The disc brakes have gone on my mountain bike (why do some manufactures think they can make them out of plastic).
Well they have a new international standard since I bought mine and everything is now a six bolt rotor and mines 4 so I have to buy two new wheels as well so $500 with new brakes $600 but i can but a whole new groupset for $1100
(like getting the whole motor gearbox and brakes attached for less than double the price)
So now I'm going to be $1600 bucks out of pocket and no closer to even buying that rear skirt I want.
