Only Custom Builders do the logical thing Front disc caliper mount on the front of the right fork Blade.
then the braking forces, torque center is the brake pad, push the wheel axle into the dropout, not out.
though some make a compromise .. the fork tip opens Forward, not down.. German Tout Terrain does this on their Trekking Bike rigid forks ..
Cash ready for $2000+ bikes to get the through axle fork , then great..
