The only 4 bolt 180 mm I could get was a Hope mini. The depth of the rotor circumference (where the pad does its work) is significantly less than that of the original julie rotor. The hope maxes out at 14mm and the julie rotor is a constant 17mm deep.

Will the hope rotor work ok? or should i toss the 4 bolt hub and look for a 6 bolt replacement.
Any and all comments welcome
Cheers
