Like this or lengthening the frame? A drop loop could also work. The 1.1/8th really opens a lot of doors though. Same for the canti bosses on the rear, avoids having the sprocket and a disc brake so close. Grease on your rotor and abrasives on your chain, awesome!
I suppose i could drop loop it, it has the ground clearance. Lenghten for sure. Going to cut it, may as well improve while i am doing it.
Keystone brackets give better ground clearance and use the engine as a stressed member of the frame and allow more diverse insertions.
Hydraulic cantilever would be amazing. Sure is a much better idea than using a disk hub.
