How is the axle kept in place with the new type of vertical adjustment system (like on the new Arcade, the Marino, Ozonys, Zoot Pro and others)?
Mostly, there is just one screw. Ozonys have another one perpendicular to the chain direction to press the slider onto the frame to prevent
it from moving forwards under chain load, so do the others also rely on this principle, but just use the axle screw for this instead?
Or in other words: Does it work properly, i.e. better than the annoying snail cams?
