The machined cups are strong and well designed, although they need to be 3.5-4mm deeper in order to actually interface with the seal lips and create a dust seal for the bearings. The tapered bearing cages seem brittle but I have not run them yet, so TBD.
These can be run on a hobbit but require mods: use 2 "upper" style cups, cut 10mm off the top of the frame fork tube, then open up the inside of frame fork tube upper and lower with a dremel and a sanding drum (about 1-2mm) to fit the 30.8mm cups
