I had/have this with 180 mm brakes on my Spitfire v3. You will want to talk to Banshee or the shop you bought it from about it.
Not really. Tried two different brakes, two different rotors, four different types of pads (including MTX.) Bolting a 100 g weight to the dropout was the only thing that worked, but that isn't really a great solution.Were you able to correct the issue?
I also get it with the 180mm disc, but its not bad enough that its unusable.
